Done.

Nothing special, battery will degrade, most user found it is useful for 1-3years, depending on how frequently they use the battery, generally, it have around 200-300 useful cycle. Charge and discharge one time count as one cycle, most precisely, if your battery is 4400mAH, every 4400mAH discharged count as 1 cycle.

Some battery when it capacity low, it will trigger some protection because cells have inequal impedance and therefore render the battery useless or lose it functionality.

Am only doing battery repacking, please read the first page of this tread for more information, 1520 can be done no problem.

Do you mean a PM, will reply soon, sorry on a vacation, will back to work next week. Have replied all email, what is you nick in email anyway?

Sorry on a vacation 9 cell battery RM280 for 85WHr, if want lower capacity and cheaper please PM me.


Ya, correct after 3 months RM50 will be charged for repair, but don't worry, not even one people have pay this before, if this happen to you, you will be the first one being charge for RM50.

That is normal, Since Window Vista or maybe earlier, microsoft begin to count the remaining time not fully depending on battery ACPI, the time remain is calculating base on the speed of the percent drop, for example, if it have been drop 1% in 1 minite, there are still 99%, window will report approximate time remaining as 99minutes, this calculation give a better precision the longer the time the user use the notebook.

I usually download file with IE, I do not use tool like flashget or bit commet, I have notice that the download time is usually show longer than what it actually need, when it closed to 100% download, the time remain become more and more acurate. The same things happen on battery, microsoft usually show less remaining time that the battery actually last, but the more close you use it to 0%, the more accurate it will show you. When you have 100% charged battery, you are worrying about how long it last seem meaningless, because it can be vary from 2-4hours. Only when perhaps only you have 10% remaing or 10 minutes remain, it is important so that you can save and close your aplication or look for a power plug.

It have to be notice that, when you use a battery, sometime you draw more power because maybe you are watching video on youtube, then the percent drop faster, later you close the youtube window, the % drop slower, that is the factor that affect the time remaining. Even original battery user will experience this. The system power management just try to make your battery last more hours. The usage of a 6 cells battery normally vary from 2-4hours, depending on the user activity.

The 5570 one will run slight longer than your original unit, around 15minutes to half an hours extra cause your original unit is 4000mAH. The IBM one, I don't have high capacity stock now, depending if you want 4400 or 4800mAH. will last around 15minutes to 45minutes less than your original unit.

Thank you, thank you...


RM180. 4400mAH, gurantee do better than your original 4000mAH or else you can have your money back.


Can be done no problem, RM180, 6 months limited waranty, 1 year customer care service.

Check your battery for details, if original unit is 4000mAH, can replace with 4400mAH RM180 or 4800mAH RM200. If original unit is 4800mAH, I suggest you replace it with 4800mAH. Within 3 days can be done. Can also post it to me, PM or email me at mail.altbattery@gmail.com. Thanks.

With regarding the capacity question you ask this morning, simple math, check original battery for capacity, if your original unit is 4000mAH, using 4400 will give you 4400/4000~=1.1 mean 110% runtime of original unit, if your original unit last 2 hours, it will last around 2hours20minutes.

I can, however tell you, same battery can last vary from 2-4hours with different usage, if you want long battery runtime, go to battery option, choose power save mode.

The time calculation should be activated after 2 percent drop. Thanks for feedback.


Yes RM140, postage add RM5 for Penisular Malaysia, RM10 for Sabah Sarawak.
