Preferred Solution: reasonable battery capacity?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

I have an X230 with 6 cell battery. The OS is Windows 8. I've noted that the design capacity and full charge capacity are both lower with 9 cycle counts. The design capacity is 57720mWh and the full charge capacity is 57420mWh while these two figures should be 62160mWh for the new battery. I know that the full charge capacity will be reduced after use while I have two questions: 1. Considering there are only 9 charging cycle, now the figure are too low for the full cycle charge. It means 7.6% loss after 9 cycle charge. It is so ridiculous. 2. Why the design capacity is reduced? Is it should not be changed, right? I noticed a knowledge base lead abt the design capacity. http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/Design-Capacity-appears-to-be-changing-on-m... While my OS is Windows 8, there is no Power Manager, so I can not understand the explanation exactly and do not know how to recovery the battery. Pls kindly check my questions and help me to figure it out, thanks!

Answer:Battery design capacity and full charge capacity are lower

I could think of one reason why it might be like that. Lenovo might have artificially limited the max full capacity of the battery in the batterypack firmware (it was suprising to me that battery also has its own firmware!) so that there is never a overcharge on one of the cells inside the battery pack. I've seen this in a Toshiba Portege R835 laptop too. It's nearly impossible to have exact same capacity for each cells (called cell balancing), so when you try to charge a batterypack with 95% charge all the way up to 100%, one cell might already have reached its 100% (this is the inferior cell) while one cell is only at 90% (this is the superior cell). The batterypack will try to keep charging all the cells resulting in overcharge for the inferior cell and degrade it even more quickly. By limiting the maximum capacity to less than 100%, it helps prolong the battery life, and similar effect can also be achieved using using the PowerManager tool in Windows 7 by restricting the charge threshold (configure the setting so it stops charging at 90% for example). I don't know why they don't create a Windows 8 version though. So in Windows 8 what I do is add a registry key which limits the max charge capacity. This needs to be done only once, but if you ever see it behaving differently, then you could re-add the registry key and it should work again.  Below is a .reg file that I use to set the battery charge only starts at 70% and stop at 90%. Windows Registry...

I am going to buy  new battery for my Dell xps  L502x early 2011 15 inch laptop  which came with 6 cell battery.
I want to know if dell supports 9 cell battery in my laptop
And should I buy batteries manufactured in 2014
Does dell stoped  manufacturing the battery for this model.  I would prefer 2016  manufactured battery

Answer:Dell xps L502x battery manufactured with date 2014 will have same capacity in 2017 or does it loose some power holding capacity

Hi JAYESH GHARAT,
The 502x supports both 6cell and 9cell batteries. Kindly find the specifications here - http://dell.to/2iVELAQ- see page# 98.
The 502x is considered obsolete and I am not sure if the batteries are available with Dell any longer. 
You could contact our team to get a quote for a battery if available - http://dell.to/1vnT6CQ
You could alternatively order the parts here - http://bit.ly/2jgRfQ6 or through other 3rd party online stores or local stores.
Also, please click my DELL-username and write me a private conversation with the service tag and your contact details(Name and Email) for case records.

Hello, I recieved a message the ohter ay telling me that my battery capicity is now at only 75% of what it used to be (laptop is two years old now so thats to be expected). However now whenever running on battery there is always a Exlimation icon with a message about replacing the battery. Is there anyway of dismissing this message as it is quite annoying. Lee

Answer:Battery Capacity Warning - suggesting replacing battery. Can not dismiss the message.

in the power manager under alarms you can turn it off power man. version 2.43 but you have to set up a power plan and use that plan to keep it  off

I've bought L430 with pre-installed windows 8 in December 2012. After 8 months of using, I don't have any problem until 2 weeks ago, the battery designed capacity has changed from 57Wh to 50Wh. I notice that I left the laptop pluged-in almost time in 2 weeks. I searched and read many topics, they said that the Battery Health Setting may be the cause of changing battery capacity.
 
There're 2 mode:
- Optimize for run time: for stay unpluged
- Optimize for battery health: for AC-pluged-in
 
Battery Capacity is 50Wh instead of 57Wh

And under Lenovo Power Setting I cannot find any setting for Battery Health Mode. It just show up what mode is using so I think that it's automatic
 
But in the following topic, they said that we can manual change the mode: https://forums.lenovo.com/t5/tkb/articleprintpage/tkb-id/[email protected]/article-id/396
 
I dont know what's my problem rightnow, I have updated to the lastest Lenovo Drivers and Software, why it didnt show up the Battery Health Mode option

I got my E220s a month and a half ago. The battery started to lose its full charge capacity from first day. Every time I use the laptop on battery (normal use, never going below 10% of battery, and usually just up to 40-50%) the full charge capacity drops down more or less when recharged. If it is used daily the capacity drops some half a percent each time it is used on battery, and if used after a week of being plugged in A/C the capacity drops several %. It's crazy, it looks as if the battery is programmed to lose some half percent capacity per day however you use it! And now, the battery full charge capacity is 20% less than the full designed capacity which it had when I got it 45 days ago, basically knocking off 1 hour of already weak 4-5 hours of battery life. And going down little by little every day. I tried to reset the battery from Power Manager few weeks ago, but the full charge capacity increased just a little bit, and then continued to go down again. Crazy question - does anyone know what I need to do - do I have to wait for couple of more months until the battery wear eats entire battery and then ask for a replacement, or can I ask Lenovo for a battery replacement now? I tried using the battery firmware update on E220s driver download page but my battery FRU (42T4935) is not in the list of batteries that "need this firmware", which aparently fixes EXACTLY this issue (well, not sure if this battery firmware just stops further battery wear or it...

I recently looked into downloading battery meter gadgets for my sidebar, but every one I download is telling me "by battery has reached 65% of its original capacity" and that I should "talk to my retailer about acquiring a new battery." I have an HP computer, so could this have something to do with the fact that the gadgets also have trouble finding out how much time is remaining on the battery, or is this a legit problem? I've had this computer less than a year, so I shouldn't have any capacity problems at this point.

P.S. If it means anything, the Ubuntu battery meter told me the same thing when I had that OS on my machine.

Hi, I have a T61p whose 9-cell battery is about 15 months old. Power Manager tells me:"The battery 1 can only store 69% of its original full charge capacity" I use this laptop plugged in about half the time, and the other half at school where the battery gets used until it's pretty low, sometimes as low as 5% or so. So in a little over a year, I have lost over 30% of the battery capacity.  Does this sound fairly typical? I'm just wondering if there is any way to slow the loss of capacity or regain any of it.  At $150 a new battery isn't fun to think about.Message Edited by Hellbore on 01-27-2009 03:39 PM

Answer:Battery loosing capacity

Mortal,
 
You may need to update your BIOS - Please see this tech tip and associated updates which I believe will resolve your situation.
 
"This battery firmware update utility fixes an issue where some batteries indicate an incorrect full charge capacity value. Because of this error, the amount of energy available for use is artificially low, decreasing the amount of time the system can be used on battery. The fix is entirely contained in the battery firmware update; there is no need to replace any hardware for this problem."
 
The battery firmware update is applicable to the FRU part numbers shown below. The battery firmware update will change the FRU number electronically stored in the battery (which is reported by Power Manager). This is done as one way to confirm that the battery firmware update has been completed. Obviously, the printed label will still show the "old" FRU number.

When our T60 has a new High Capacity Battery in it and is also plugged into the power outlet, when the charge gets to 100%, the laptop shuts straight down.  If it is just on the battery, it stays working until the battery is empty, and if the battery is removed and the laptop is just on the power from the wall, the laptop stays on indefinately.  This battery is a replacement for the same problem.  This problem happens in any of my several t60 laptops.  Is there some setting issue?

Answer:T60 and new High Capacity battery

sounds more like a hardware issue, if you got warranty you should get it fixed. If you don't have warranty, just go into the Thinkvantage Power Manager, and set your battery to stop charging at around 95% level, which may prevent it from a self shutdown problem that you described.

Recently my T510 9 cell battery suddenly stopped working.

Before the failing it lasts 3-4 hours and charges normally.  I read several posts online and see some people have similar problems. It is suggested that maybe one of the cells fail so the circuit stopped the battery from working/or the safety circuits just malfunctions? Or indeed I need to replace the battery. I understand that messing with battery is risky and I believe it is detected as not working for a good reason. However,  I am wondering if there is a way to assure that my battery is completely dead, but not a problem with other hardware or the OS, before I purchase a new battery.

Does anyone know of good software that checks the actual capacity of your notebook battery without recalibrating it?

Best Buy just sent a new battery for my notebook, but the battery was scuffed up and looked used. I knew the "Cmart Battery auto-learning" (Rev 1.2) function built into the bios measures the actual capacity, but after running it on this battery the results I got were:

Capacity before learning: 4807 mAH
Capacity after learning: 4737 mAH

Kinda feels like the battery was actually at 4800 before recalibrating/learning but now I just shot myself in the foot out of 70 mAH. Not a big deal, but I would like to check the actual capacity of another battery without risking making it worse.
Also, anyone know if it is possible to revive batteries? I have a battery for this notebook (Gateway MX6453) that only gets a 15 min charge. After running the "Auto-learning" feature it said the capacity was only 600 mAH.
These batteries are original 6 cell gateway batteries for the MX6453 (4800 mAH spec capacity)

Has anyone found an 8 or 12 cell battery for this line of notebooks? I have looked but have found nothing other than the stock 6 cell 4800 mHA battery.

Thanks...

Try draining the old battery completely to reset the "memory"

I have a Thinkpad X61 with Win Vista Business that I've been using for pretty much two years. A month ago I could still get more than four hours of battery time according to the Power Manager; since a few days my battery capacity is suddenly at only 47% of original capacity and won't give me more than one and a half hours. I know this kind of battery is supposed to get worse/degrade as time passes by, but how come I lost basically 50% of capacity in less than a month?! Since batteries are so extremely expensive (I have no idea why; it doesn't make sense) I checked for alternatives online. When investigating, I noticed that my battery clearly states 14.4 Volts on the label, while the Power Manager claims the battery is 16.6 Volts. This doesn't seem right. Could this be a reason the battery isn't working right - a software glitch? Is there anything I can do to "rescue" my battery, or is the my option to purchase a new one? Any thoughts on where I can get the best deal? Thanks,  Per Bylund 

Answer:Battery capacity halved in less than a month?

bylund, This sounds unfortunate, and perhaps like one or more of the cells in the battery is failing, and when the others discharge to a certain level, the overall voltage in the pack is dropping below the plateau that the intelligent chip in the battery pack recognizes as what would be the 50% charge point. It may be that you just need to replace the battery pack if this is the case. We just came out with a tip and a battery program for some specific models and batteries today - I don't know what your battery FRU number is, and it doesn't sound like all your symptoms match, but it might be worth checking out the tip and running the tool to see if your battery qualifies.  Here is the link. Best regards, MarkMessage Edited by Mark_Lenovo on 08-05-2009 08:25 AM

Hi there, I recently bought a ThinkPad x220 with a 9-cell battery, thinking that it would help me get through the day without a charger. However, it seems like the battery is quickly deteriorating. It's been around a month since I purchased it, and the battery stat shows it's had 18 cycles of charge and discharge. I've made sure to never drain the battery down to 25%.  The capacity is reported to be at 97.4% of design capacity! Another laptop I had from Dell only dropped down to similar figures after a year. Should I be worried? Is there anything I can do to mitigate? Or is this battery flawed in its production? Answers would be greatly appreciated.

Answer:X220 9-cell battery capacity?

Hi nzguy, and welcome to the Lenovo User Community!
 
What you're seeing is normal for a lithium-ion battery. In normal use it's going to last 2-3 years.
 
Hope this helps explain!

Battery on my new X770-107 had wear level of 36% out of the box, lasting for 45 minutes or less.
I had had it replaced for another one in authorized service centre. The very next day, that brand new battery had wear level of 17%. Clearly, something is wrong with batteries in this notebook or every application I've tried to test it with is buggy (BatMon, Battery Eater...).

I'd like to make a comparison.
Could somebody post his/her max. charged battery capacity and wear level using BatMon (or some other application)?

Answer:Qosmio X770 battery capacity

I called in today about throttling issue and the instant battery wear of 21% out the box.

This may be bogus readings from API chip set from reading other post.

However, both these issues have been promised escalation and an answer before my return rights are up.

Hopefully they will address this forum directly?

Hi, I bought this X61 in November 2008. The battery came along with it was made by Sony, everything was fine till 2 months ago. The battery  was  losing its capacity to 43% in 1 week and I soon found that I could boot with battery. I checked the  battery status  it said this battery could not be charged. I did make sure that I had treated my battery carefully and followed every step on the manual and the tips on lenovo site.  I have another thinkpad  X41. the battery is still perfect after 4 years.  I checked with my friends and online forums. A lot of people said they had the same issue. the battery died just after around 1 year, so I would assume that this is not just my problem. It is common in X61 users. My problem is , Do Lenovo know this issue ?  Are you gonna do something about this?  I  am not sure if I should buy another battery for  replacement because I do not know if this problem will happen again. Thanks for your attention. My thinkpad is X61 , type 7675-CTO Message Edited by chakir on 02-06-2009 11:28 AM

Answer:X61 battery capacity decreased right after out of warranty

Chakir, Thanks for sharing, and sending the additional information via PM.   Based on this information, while your battery is still relatively young in terms of age (14 months +/-) the charge cycle count is very high, and I think it reflects a reasonable service "mileage" out of the battery. You might compare your charge cycle count with that of the X41.    My tablet is two years old, and my charge cycle count is 240, on a Sony battery and I still have 55.43 Wh capacity remaining vs the 66.24 Wh design capacity.   It may be that your battery is just wearing out based on the number of cycles. Best regards Mark

Hi, I have a W520 with a 9-cell SANYO battery, FRU 42T4799, Bar code: 1ZJRC21WLPS, Serial Number: 22564. My problem is the following: I've been only using the laptop for 2 montth, but the battery already has 9% wear. Before I've been using an Acer notebook with a Panasonic battery, what didn't even have 5% wear after 2 years! Is this wear normal? Should I contact my warranty center for a battery replacement? My other question is that I see no options about changing between Maximum Runtime, Maximum Lifetime and Battery Health. Actually the only place I've seen this is in forums and in the Power Manager's help. It's definitely not present in the Battery / Battery Maintenance... / Screen. The only thing I find there is the 3 choice with the second having "notify me when charge mode changes". When I installed Power Manager (latest), it set it to some mode that the battery became smaller. Now I've set it back to "always fully chrage" and now my battery's design capacity is back.  Can you explain me these different battery lifespan extending modes and actually what they do? Where can I set them and where can I view them?

Answer:Battery capacity question in W520

The battery capacity becomes smaller in maximum lifespan mode because in that mode, the battery never is at 0% or 100% power states (the worst states for Lithium-Ion batteries). This can help the battery to last longer by causing less wear-and-tear on the cell and a lower cycle count. In maximum runtime mode, the battery shows its entire capacity and will charge to full and discharge to empty. This provides extra battery life, but can possibly also increase battery wear and number of charge cycles if the battery is often kept at either 0% or 100% for long periods of time.As to where you can find the settings, you found them. You can either set the battery to always fully charge and discharge, allow Power Manager to automatically adjust the battery's charges and discharges in order to extend battery lifetime, or manually set the maximum charge percentage you would like in order to extend battery lifetime.

Original battery on my X60s died and I decided to purchase high capacity battery for it. I bought 8 cell battery (40Y7003) that Lenovo website suggested according to my model number, but it doesn't fit! It fits binding, but it is thicker and tighter than 4 cell I had, and when 8 cell is installed, because it is thicker, my laptop could not be balanced. It is like a table with one leg shorter than others.  The question is what batteries suites my X60s. Only 4 cell (40Y6999), or I can combine it with extended life battery (40Y7005), or there are other high capacity batteries that can suite by laptop?

Hello people , as is it mentioned in the title the battery capacity of my ideapad which i bought it s been now 6-7months dropped from 60Wh when it was brand new to 52.6Wh for the moment also the autonomy from 4h20m to 3h40m/3h30mand my question is :is this normal ? I mean yeah it s a normal loss , but i didn t used the battery that much , most of the time it s on conservation mode for the games or video/audio editing,maybe it s the temperature ;sometimes it reaches 41°C but i don t know if it s harmful for the lifespan (if yes , what is the maximum temperature for a Li-ion battery?);and the number of cycles is 68. Thank you in advance

Answer:Battery capacity droped from 60Wh to 52.6Wh

Run it down and take out of conservation mode and when its back to 100% see what the capacity is. Run times are not great even with minimal use of email and some browsing as I was using mine yesterday on battery after charging fully from Conservation mode. I had work done in the house and had to move to a different area so I just ran on battery. OEM runtimes are quite optimist with saving modes all on and performance mode off etc I am sure. A few watts lower is no big deal but if its way down before your warranty gets around 10 months I would contact Lenovo for a replacement battery.

Hello, I have Lenovo G580 (2689) for last 6 months. Its battery lasts for more than 3 hours. Battery capacity is 43200 mWh. I want to know what capacity is expected in a new battery? I didnt see it when i bought. only recently i have come across all this. So what capacity should i have when i purchased my laptop. Is current capacity ok or needs some repair?   

Answer:Lenovo G580 battery capacity

hi firozmkhatri,
 
The Lenovo G580 (2689) uses a Lithium Ion 6-cell, 48Wh battery as per this pdf data sheet. Since 6months have passed, your current 43200mWh battery capacity is still ok since battery do degrade overtime due to usage, aging, and heat.
 
If the battery last an hour or less on full charge then you may need to contact lenovo for a replacement battery.
 
 
Hope this helps.

My T60P is about 9 months old, and always had very good battery capacity. I used the laptop on battery power regularly to keep the battery in shape. But  two weeks ago the capacity at the battery information dropped from around 98% I believe to 8%. This was from one day to another and for no apparent reason. I thought there was something wrong with the software but the actual time the battery would last also dropped an hour and 10 minutes. I could only work on DC power for 10 minutes.I have tried to do battery maintenance but that caused that I only have 1% battery capacity at this moment.Is this something on a software level or did my battery break down?

Just got a 2nd hand Dell D400 which im very happy with, but... as expected the battery life is poor (an hour).

I have been looking online ebay) and seen batteries with capacities of 1900mAH, 3600mAH and 3800mAH.

I believe the battery i have on the Dell is the 1900mAH and im also guessing its the standard battery.

My question is... if i purchase the 3800mAH what kind of battery life should i be expecting on average If im getting about an hour on the standard 1900mAH and the stated battery life (taken from kelkoo ) is 4 hours.

Another question... does the 3800mAH weigh more? and is it physically bigger?

Hi,

I have a dell XPS 13 L322X that I bought in 2013. Recently I bought a new cooling fan because the original one was very noisy. However, after replacing the cooling fan, I noticed that the battery capacity dropped to less than 10%. Therefore, I decided to buy a new battery. The problem is that the capacity/health of the new battery dropped to 75% in just a few days. I contacted the seller explaining him the situation and he sent me a new battery; however, the new one has already lost almost 50% of its capacity/health in just three days. One thing that I noticed was that the (second) new battery has an Energy (design) of 50,2 Wh whereas the original one and the first battery that the seller sent me both have 47 Wh. Another thing is that while I was calibrating the battery, in the first cycles, the battery was charged only up to 90% and that the capacity loss happens after a reboot: in the end of a cycle there is a decrease in the battery capacity after a reboot. After a reboot, the system shows the battery is fully charged, but with a decreased capacity. Every single cycle the capacity drops. The XPS 13 is running Ubuntu 16.04. Would you have any idea why that’s happening?

Many thanks.  

Answer:XPS 13 L322X: battery capacity drop

Sounds like you may be getting batteries as old as the original one - there's a date code on the battery you may want to check out (it's part of the Dell part number -- you can find out how to decode it online).

The updated battery manager helps fix this as well as you letting you battery go all the way down to 10% and then recharging. If all else fails run the battery manager update and the reset the battery and your problem should be solved. It is not a big problem but I am **bleep** about not having gauges display correctly. Happy computing, Leighton

A few months ago I bought a new 9 cell 44++ unit, for a couple of months my battery life was phenomenal, but after some time it suddenly dropped ( I don't realy remember when it happend) I decided to investigate a bit more into the issue, and found out something very weird: Checking the design capacity report in Windows Battery report - it seems that between the dates :2016-12-05 and 2017-01-30 the design capacity was around 90 Wh, however from the middle of february , the design capacity dropped to 40,400 mWh. Also inside the Lenovo settings app - it says that the 45N1027 model - has a design capacity of 40.4Wh only (which is wrong) I think I updated the battery firmware some time ago, and maybe that caused the problem. I tried running the current battery firmware update utility again today, and it says I don't need to update my firmware.

Answer:44++ battery design capacity dropped?

I have never seen this behavior, but I don't have an x230 to test with.  Did you buy it from Lenovo?  It should have a 1-year warranty.  You might try a battery gauge reset at the bottom of the battery section on Lenovo settings.

If so, looks like they sold you a 1 year old battery which would have already lost some capacity just due to age.  For it to fail so soon after you have started using it is not normal.

I have always followed the instructions in the manual about running it on battery, then charging, not leaving it on mains etc. Can anyone advise me what to do - is the battery covered by any warranty etc, and who do I contact about it.

Answer:Problem with battery capacity on Equium A210

Hi

Generally the battery life time depends on the notebook usage. If you run high-performance applications like games, DVD movies, graphic applications then the battery power discharges quicker.

It sounds very strange that the notebook needs more battery power after the BIOS update.
However, if you think there is something wrong with your battery then contact the ASP in your country for a check?

I have done a gauge recently but since then it shows battery capacity as 629Wh! That's even more than 10 times of original 48 Wh. There has been steep  decline in battery backup since then and get about 3 hrs without wifi, which earlier used to be more than 4 hrs. Several times I retried gauge reset but it has been of no use...

Hello everyone! I'm a happy owner of a ThinkPad 470P purchased more or less one month ago.I've completely wiped Windows 10 in favour of Debian, kernel 4.9, and everything runs smoothly: my GPU stays idle when necessary thanks to bumblebee, my CPU (i7 7700HQ) runs smoothly and the kernel manages it correctly, cores stay in idle state when necessary without issues. Until a couple of days ago, my battery was letting me work for 7-8 hours without needing me to plug my AC in, with occasional peeks to 10h (I have got the 72Wh version). Suddenly, the maximum capacity of the battery dropped below 50% (42% at the moment), without any apparent reason.I've already run a couple of tests, such as tlp recalibrate, to attempt a recalibration and/or detect common issues, but nothing suspicious was spotted. I'm quite an attentuous user, I avoid plugging my laptop in when not necessary, I always wait for low battery levels (5-10%) prior to recharging and I happened to detach it from the AC before it being fully recharged just in a couple of occasions. So, I wonder whether there is any specific issue with battery drivers on Linux (but it is said to be fully compatible with Ubuntu, which is a surrogate of Debian, which I am running o.O), or if a possible issue might be battery deterioration. Which I believe is handly possible: the battery has just one month (or so) of life. Since I am seeing many issues related to battery on Linux on ThinkPads, I believe there is so... Read more

Hi,

I am looking for alternatives to the U200 standard battery (PA3356U-3BRS). Some online retailers offer a third-party high capacity battery which they say is compatible (try Froogle for example). The specs are:

Type: Li-ion
Voltage: 11.1V
Capacity: 8800mAh
Weight: 628 g

From the pictures it seems that the battery will stick out at the back of the notebook, similar as the Samsung X35 standard battery. I wonder if anyone can confirm that this kind of battery in fact works with the U200/U205. What runtime gain do you experience and how long does it take to recharge? Can you recommend it?

Jan

Answer:Satellite U200 - high capacity battery

Hi

You should be very careful with 3rd party batteries. The wrong battery can damage the notebook!!!
So I would not recommend using any batteries which are not especially designed fro your notebook!!!

Do you know the Toshiba Options & Accessories website? You can find it on the Toshiba Europe page.
http://eu.computers.toshiba-europe.com -> Products

There you can find a list of compatible parts for your notebook.
So check it and purchase only the recommended parts :)

Satellite Pro L50, I had a warning box appear from the Toshiba PC Health Monitor which said

"Your battery charge capacity is relatively poor.
After a period of time, the battery will lose its ability to perform at max capacity & may need to be replaced. This is normal for all batteries. For more info about the 'poor' charge status click the help button."

Clicking the help button indicated the battery condition at about a third charge capability.

Is this an indication that I need a new battery?
The laptop is only 4 months old & I have some concerns. Comments appreciated

Regards, Mooky.

Answer:Satellite Pro L50 - poor battery charge capacity

If notebook is 4 month old I recommend you to contact your local dealer or nearest Toshiba sevice provider directly and explain the situation.

You must clarify this with them and maybe you will get new battery for free.

Addresses and phone numbers you can find on http://www.toshiba.eu/innovation/generic/ASP_SUPPORT/
Don't wait. Call Toshiba service as soon as possible.

Hello,i am using a P40 Yoga and i am not really pleased with its battery runtime. So i checked the battery health in the Lenovo Settings Tool and discovered, that the capacity of the battery is down to 70%. From initially 52,55 Wh there are only 36,91 Wh left, after just 137 loading cycles in about 17 months of rare use... Has anybody else made these observations? Is there a chance to get a replacement battery even if the warranty is expired? Thank you for your feedback Matthias

Hello :(
my question is, if I can use a better battery for this notebook, because it's really weak, I have to charge it after 1 - 2,5 h. I saw I could use another battery but that's impossible, because the battery i saw here, was like 10 cm bigger than standard one. It won't fit, right?
Thanks for help & sorry for my bad English. ;)

Answer:Need high capacity battery for my Satellite L650

As far as I know for Satellite L650 don't exist high capacity batteries but only original with 4400mAh capacity.

Don't use other batteries who are not compatible for your notebook model and this bigger batteries will not fit your notebook.

What you should try is to reduce power consumption. Use ?Power saver ? power plan. Reduce display brightness, close all useless running applications and disable all devices you don't need.

I've bought an E325 about a month ago, mostly used it from AC source. This weekend it was turned on and used constantly 2-3 days from AC adapter, but the battery was left in. The power level was on 97% when I restarted the system, after login the Power Manager gave me a pop up about it has corrected the maximum power capacity of my nearly brand new battery. I'm really upset now... at first Power Manager said that the design capacity is about 62Wh, then after that restart (battery only did 5 cycles, it was on 97%) it was lowered to 57.72Wh and the maximum capacity is modified to 56.03Wh. At that point my remaining capacity was somewhere about 61Wh according to power manager. Next day I used my laptop, drained it to about 10% and then fully recharged it, now it charged my battery only to 56.03Wh... How the Power Manager come to  modify the DESIGN CAPACITY of my battery?! It's not set in the factory? Why it changed my nearly new batterys maximum capacity? I'm really upset right now... If iI use my laptop from AC voltage with battery in it for some days and it drains some percents, this **bleep** piece of code always lower my capacity and I will have to throw away a nearly unused battery? I don't think that the program can predict the aging of my battery, especially that it even not tried to recharge my battery to original design capacity, it instead lowered it without asking me! What can I do now?

Answer:E325 lowered battery capacity after 5 cycles

Do you have green line around your battery gauge? This would mean your battery runs in "maximum lifespan mode", which automaticaly lowers maximum capacity to +-90% (62->57Wh in my case). It can be changed to "always fully charge" or custom setting.

I got a ThinkPad x230 i5-3360M about 6 months ago. I run Linux Mint Mate Maya (13), and this is hands-down the best laptop I have ever had the pleasure to use. Lately, however, the battery life has been deteriorating noticably. The 6-cell battery now lasts only about 3 hours on a charge, and indeed upower -d reports that battery capacity is down to 45.5301% Is this a hardware defect, a Linux issue, something about the way I'm using it, or what? I thought I would ask here before calling Lenovo -- I have 3.5 years of full protection left on the warranty, but something isn't right, and maybe there is a simple fix. Thanks. 

Answer:Battery capacity deteriorating fast on x230

I logged into Windows and checked the "Power Manager" app. It reports the battery condition as "poor" with 45% capacity (exactly what the Linux tool reports) but only projects 2 hours of life on a fresh charge. Power Manager also reports that the battery was manufactured just one month before I started using it last summer, and that there have been 66 charge cycles to date. Unless anyone has any suggestions, I guess I will be callng for warranty service.

Hi,  I have a look at my battery report today and found something really awkward. I bought the computer seven months ago, and the battery start with Design capacity 44,000wWh, while the full charge capacity is quite closer to the design capacity. However in the battery report it shows that two weeks ago the design capacity suddenly drop from 44000 to 40734mWh in one week, and then afterwards it drop to 39000mWh. And the actual full charge capacity seems to linger around 37000mWh. Is there something wrong or is my battery just wear out naturally? Best,Eddy

I currently own yoga 710-14 with i5-6200U cpu. I managed to install windows 8 on this device. I installed battery bar application that shows battery usage. After few first charges it started showing that my battery quality is becoming worse. Now after 3 weeks it shows that I lost 25% of my battery max capacity. It's 39900mWh from factory 53000mWh. I charged it less than 20 times so it shouldn't die so fast. At this rate I will reach 0% capacity after 9 weeks.I charge it for about 4-6 hours, then disconnect, and use until battery reaches ~10%. Then I turn it off and charge until full. I never use it during charging, always on battery.However I am wondering if it is battery fault or it's just windows 8 incompatible with my battery meter?I installed some kind of lenovo battery tool to check if my battery was faulty (from faulty battery exchange campaign in the past) but it said there is no battery.I tried to generate windows report by powercfg /batteryreport but it didn't show any info.I mean it displayed:DESIGN CAPACITYmWhFULL CHARGE CAPACITYmWhCYCLE COUNT-without any values. However powercfg -energy gave me same info as battery bar and HWINFO programs.

Hi,It means that HP diagnostics has detected that the battery is capable of less than 25% of original charge and should probably be replaced. However you can try updating Bios and performing other HP diagnostic tests on the battery first to see if the error remains. https://support.hp.com/us-en/document/c01443470 Hope it helps,David

Hi, my x230 shuts down instantly when the battery is at 25-30% (around 10Wh).I tried performing battery gauge reset with no improvements, but I have the suspect that it doesn't run the full charge-discharge-charge cycle since it shuts down (I didn't attend the full cycle so I'm not sure).I had a wrong "full charge capacity" reading in power manager which I solved switching charge mode in Battery Maintenance from "always full charge" to "optimize for battery health".The battery firmware update tool is not suggesting an update, so I'm apparently out of options.  Thanks in advance for any help

I received my T440s mid-December, and both batteries had a capacity just above 23.2 Wh (design). After maybe a month or two, the capacity dropped to ~90% on both batteries. Today one of them dropped to 82.8% and the other is at 89.1%, but I have a feeling it will drop to the low 80s in a few days.  15%-20% capacity drop is not normal for 3 months of use, correct?

Answer:T440s - battery capacity dropping fast

Having the exact same problem, capacity dropped to 90% after 2 months. I decided to remove the removable battery and not use it to preserve it's capacity. If this is normal, it's pretty appaling... At this rate the capacity will be diminished completely after about 2 years... Not a nice prospect.

I have a Dell XPS M1530 that turned one year last week. During that week I made screenshots of the CPUID-information delivered to me. I use this wonderful piece of software to monitor the temperature of the notoriously hot computer, and after mye last harddrive-crash I found the new version contains information about the battery, too. I wonder: How can the current full charge capacity swing so much on a day to day basis? And is it normal that the battery has lost 16% of its capacity during the first year? Even though lithium batteries are not supposed to have a memory-effect, I still cling to the "empty first, load thereafter"-strategy, and have had good success with that on cell phones. But the Dell disappoints me (as it does in any other respect anyway - 2 new harddiscs, new motherboard, and a new battery already in week one are the results of the first year's use and maintenance need. Never needed maintenance on any PC or notebook ever before, PC-use since 1994).

Best regards

Answer:Battery capacity development over a week, and a year

16% loss after one year is reasonable. ok, so not all battery manufacturers have "accurate" battery wear level but i will post mine: i got 2 laptops with accurate battery so far (acer TM4000 and 5930G)

the latter, was bought in early dec 2008. so today, after about 1.5 years it has 31% wear level. now = 48988mwh. was = 71040mwh.

in my case, the level get worse if i use the laptop everyday on battery. once I kept the battery and use the laptop as a desktop replacement the level barely increase. one tip to keep it is that to "calibrate" your laptop battery as often as possible. In some cases I successfully decrease the wear level by doing that. It's clear that short discharge of battery actually worsen the age of the battery itself.

I saw few sony vaio & toshiba laptops, with battery wear level at 0% but battery dies within 5-10 minutes of usage.

Hello, I've had my IdeaPad for not even one week yet I observed in the battery section of the Lenovo settings app that the full charge capacity has dropped from 36,... Wh to 35,02 Wh which is already below the design capacity of 35,3 Wh. I've even been using conservation mode all the time and always left it plugged in so it's basically been at a stable 55-60% all the time, except for one 100% charge and back to 60 again. Is the battery really losing its capacity this extremely fast or is it the Lenovo software just artificially lowering the full charge capacity? It seems extremely suspicious to me that the battery loses capacity at 1 Wh per week....Thanks

Hi,
 
I have owned a yoga 13 since January, which I'm quite happy with apart from some well-known problems (fan noise and weak wi-fi).
 
I have however observed an abnormally high rate of maximum battery capacity loss. This is the battery capacity history report since I first got the machine:
 
Link to picture 
 
You will notice that today (November 2013) the full charge capacity of the 54 mWh battery is only 41 mWh, which is a 24% loss over 10 months.
 
This seems a bit excessive to me, and it also renders my Yoga less useful: it now lasts about 4 hours at best, instead of the 5:30 is used to last when it was new.
 
Is this normal or something that would call for a warranty repair?
 
If it's normal, does anybody know where I can get a replacement battery in Europe? Local lenovo rep wasn't much help...
