The battery status is ''Charging'' for some seconds ,when the battery light from the front of the laptop is orange(charging) and for a second it becomes green(fully charged) and the battery status is ''Critical''.The battery is also telling me ''Plugged in,not charging''.

To correct my message: Found that the battery life varied from 280 minutes to 350 minutes on the same one system in a few times tests with Battery Eater Classic Mode. Do I need to do any further Eater settings to get consistent battery life result? Thank you!

25.2.2015 - Daphne

Hello. We're using Eater to test notebook's battery life. Found that the battery life varied from 280 minutes to 350 minutes on the same one system in a few times tests with Eater Reader mode. Do I need to do any further Eater settings to get consistent battery life result?

16.7.2014 - Meia28

Error B flashed on the screen while running the Classic test. What does this mean?

You dont have a forum or support email contact to get answers about your program.And there is not a Instruction Readme for your program.And We dont even get notified of answers here.SO how can we get answers for our questions and problems?

Our software is free and very old. There is a way to get good support for it - buy it. We already think about payed version of software. Will you buy batteryeater if it will update to new version?

30.5.2014 - Logos

Im using Windows 7 Starter (32bit) and when I run Battery Eater v2.70 I get the error message "Failed to set data for "Battery Eater '05' ". How do I fix this error?what does it mean?will the app still run regardless of this message?

Windows Vista and up is not tested with batteryeater. This software is very old and we guarantee work only for win 2000-XP.

I have a notebook with 6 cell battery 10.8v 4400mAh. When testing with the Battery Eater Pro v2.7 it reports only 3 cells. I have repeated the operation on other notebooks and always the same error occurs in the report.

It's normal. 3 cells in that case means that battery have double cells. Every cell is double pack.

7.5.2014 - Alex

I'd like to see Battery Eater for MacOSX & if there's no plans in near future to publish version for macs I'd like to participate in your project to port your useful application I've been using for years on my windows laptops. If you ready to discuss this question skype me please "alexandrmatvienko"

We can potentially release batteryeater even for mobile platforms. But it will not be free as all previous versions.

28.4.2014 - Niko

Where can I download it? Thanks in advance.

From this website. In downloads section.

28.4.2014 - Niko

Hello, I would like if possible new Battery Eater 3 software, I do not care if it's beta or alpha.

It will be not alpha not beta, but it will not be free if we decide to develop it.

26.6.2013 - Fellippe - LTA-RH

The BE works perfectly on any operating system, be it 64 bit windows 7 or 8 should work as follows: For the BE should work perfectly set in the control panel / power options / Change plan settings / change configurations energy further / battery - All items that appear as hibernate, should be with the action of POWER OFF, so you will not have the white screen error B. Solution found by me - Fellippe Mendes - LTA-RH (Dell Computers)!!

do you have second battery?

13.2.2013 - Pouncytaur

BE Pro will run on Windows 8, but it has to be ran in Administrator mode, and you have to be very fast about clicking the "Begin test When disconnecting AC" checkbox before the program becomes unresponsive. It will regain response after unplugging. This may be a one time thing, but on this one computer, BE is all scrambled, the buttons are behind graphs, window graphics are different sizes than the windows... it's really odd. Win 8 compatibility is negligible at best.

7.12.2011 - iaintellingyoumyname

how long is the text the the battery reader test use? Since it stops reading after about 2 hours,and since most laptops i test can hold for 6-8hours+ it seems its inaccurate then.

Yeah, It's the book "Hamlet", and when BE was written most notebooks cant hold even 1.5 Hours at all.

5.12.2011 - End of the Universe

Hi there, in the past was written that some day in the future we will receive BE3... How far away is some day? Or are you planning to release the source code so that other developers can upgrade BE2.7 to Windows 7 and 64 bit.

It it true htat BE3 was in development. But one problem is still exists in our way to new release. Money. This project is totally free, so we don't get any money from it. Ads give us some money only to pay hosting. So I cant promise anything.

So just do it!

23.8.2011 - yeter

Battery eater doesn't detect the right amount of ram in my laptop. I've got 8gb loaded but it only detects it as 4gb. Checking on my system properties it detects 8gb. Is it a bug in the software?

Battery eater 1.xx and 2.xx is 32-bit native applications. Thus means it can't adress more then 4Gb of RAM. We look into future and will release 64-bit app too.

22.8.2011 - Jen

I was trying to figure out how to work this and opened the Gauge.exe file. A black box appeared on my taskbar by the system side. I clicked it, and it went behind the taskbar. I wouldn't have noticed, except I'm running Windows 7, so the taskbar is translucent. The black box is annoying and occasionally the numbers in it change, drawing my attention to it. I deleted all the BE data and emptied my recycle bin, but lo and behold, the black box isn't gone. There's a process in the Task Manager called Gauge.exe, but I was hesitant to end it because I don't know if it's the right one.

It is this one. Unfortunately this utility does not work properly with AeroGlass theme. Hoping it will be fixed in BE3. Thank you for your feedback.

21.8.2011 - coffeeboi

thank you!!

And thank you too!

21.8.2011 - Techie

To remove the folder you need to end the BEPro.exe process... Go to task manager/processes, then END PROCESS for BEPro.exe, once that's shut down then you can remove the folder.

21.8.2011 - coffeeboi

Can not remove your folder. Took ownership. Still not able to remove. This a virus???

Probably Battery eater is still running.

my laptop lenovo x61, after using battery eater in 76% my laptop is died, if i turned on, my laptop refuse charging, why is this happened?

Your notebooks seems to be not newer one, so battery may die away already. Stress test may catalyze this process. Battery controller often show wrong values of charging level on old batteries (more than 1 year). This show up that you must replace or repair you battery pack sooner or later.

I've ran BE v2.70 many times in the past and it always worked fine. But the latest time, after the Classic test completed (i.e. laptop turned off), I turned it on and I was dismayed to see the battery data was empty. It said run time was 0 minutes, and the graph was empty. I know it ran for many hours... I was using FAT32 system, maybe that's why?

We reccomend to use NTFS instead. NTFS provide no data loss.

Why in the battery information the designed capacity (51840 mWh) is much higher than the actual current capacity (35748 mWh)? I mean why is there a such big difference? Is there any way to maximize the current capacity? By the way excellent program :)

Perhaps your battery is not actually new. All batteries lost some capacity every day. Not much, but it can be twice less for a year. Want more - buy new battery.

I just used this for my new travel laptop (a MSI Wind) and it's a great application. Any thoughts of porting this to a Mac? Apple recommends reconditioning the battery every month, and this is perfect for it.

I get questions for porting BE to WinMobile, Linux, Mac not for first time. There is still big problem for porting. Battery Eater was developed in Borland Delphi.

22.7.2008 -

My main problem seems to be getting the BEupdated program to work ( I managed once without a crash) and to get the videa of the revolving battery to work ( i managed it once without a crash) . Most of the time i just get a gray screen with no video. IBM THinkpad T42 running XP Pro.

22.7.2008 - kwikphix

Nice idea. I bouht 2 IBM T42's and decided to see how good the batteries were before and after reconditioning. Both machines are identical but i've only managed to use the program once on one machine, all other times it just froze up & crashed. Not had a program crash on me since Win98 years ago , keep up the good work though I do realise its only freeware...

17.6.2008 - Ricardo

BE crashed on startup and couldn't produce the report. Is there another way to use the .beg and .log files to generate the report?. What is the log file? Is it the evolution of discharge?

Yes. There are other way : drag and drop .beg file over BePro.exe file, and Battery Eater will create report from it.

14.6.2008 - victore

what program will view .beg files?

Only Battery Eater

5.4.2008 - JW

Trend Micro CS detects PAK_Generic.001 & 005 viruses when using BEupdated. Not good.

Some antiviruses are very stupid. Battery Eater have no viruses or trojans (see softpedia check). There are data packers in BE that identified by some stupid antiviruses as viruses.

Hi, sorry for the stupid question regarding charge and discharge log unter normal operation conditions .. I found how to do it ...
