Welcome:

Welcome to Alternative Battery Enterprise weblog, Alternative Battery Enterprise is a small business based in Malaysia, that realt/refill/recell or even repair your laptop and notebook battery.


Alternative Battery Enterprise always emphasize on the quality of the refilled battery, you are welcome to search for our services record or user experience on other web space.

Since first operates from year 2006, Alternative Battery Enterprise maintain good customer sales and services record.

Fast turn around time, your battery will be fixed in less than one week time. Usually customers get their batteries back in next day although they are normally told 3 working day to proceed. This could be the most efficient battery refill service that really work you could possibly found in Malaysia.

Battery is backed with 100% money back satisfaction guarantee in the first month of recell. Alternative Battery Enterprise accept any reasonable reject of any refilled battery and refund will be issued immediately in 3 working day after battery is post back to us.

A total of 1 year warranty will be given!

There are 6 months warranty on battery cell, in this period you will still get a refund of 80% if your battery fail beyond repair.

After 6 months, Alternative Battery Enterprise will still fix your battery if it fail within any period of 1 year without any additional charge excluded postage fees.

Even after the warranty period, if you confirm that your battery cell is still in good condition, but battery just no working, it can be repaired at RM30! Which is the best way to ensure you get a working battery that value for your money!

Most customers reported that a refilled battery work 2-3years! Some really poorly designed (too few cell with big load) battery may last merely just 1 year, some may last up to 4 years.

New Cell Arrived

Many customers ask for higher capacity, Samsung 2600mAH battery cells have arrived. Will perform at 2600mAH, 5200mAH, 7800mAH rated capacity.

Samsung 2600mAH:
Real capacity: ~2530mAH, ~9.3WHr
Internal resistance: less than 60miliOhm including PTC inside(after make a rough measurement by my mili-Ohmmeter)

Samsung 2400mAH:
Real capacity: ~2330mAH, ~8.4WHr
Internal resistance: less than 60miliOhm including PTC inside (Around 53 to 58)


Nickel stripe (for thermal-resistance spot welding):
Resistance: 0.215miliOhm/ mm (only half compare 3mm (>0.4miliOhm/ mm) width nickel plated)
Width: 4mm

Copper stripe:
Resistance: less than 0.001miliOhm/ mm (beyond the resolution of my mili-Ohm meter)
Width: 4mm

Lower resistance electrode plate use to connect cells simply mean less energy lose in conducting due to loading effect. The cell depleted at closer ENDV (end of discharged voltage) defined by manufacturer. Then, give a better capacity measurement by the power management ic, because Voltage measured is closer to real value (less error during high current loading).


An example of my four point spot welded 2200mAH battery cells:


Strong and reliable connection, AC phase-controller welder will supply just enough heat within a decades milliseconds (only do a spot (just a dot) heat up, not full contacted area heat up) and thus minimize the thermal damage to cell (Li-ion is very sensitive to heat, if one solder it with soldering iron, the cell have risk to fail within 3-6months).

Professional grade at affordable price! Or you can return it and have your money back!
