Fits directly into the existing battery bay

A built-in smart control chip manages charging cycles and provides short-circuit, overheat and overload protection, freeing the user from external power bricks during mobile use.

Sustained output with integrated safeguards

The 48Wh capacity delivers consistent discharge over long sessions while the protection circuitry prevents voltage spikes under continuous load. Cells are tested to maintain specification-level performance throughout extended operation. Buyers needing higher capacity or a different voltage should verify their original battery label before ordering.

Questions about this item

How long will the 4400 mAh capacity last under continuous load?

The 6-cell lithium-ion pack stores 48 Wh at 10.8 V, so run-time depends on the laptop's power draw; higher loads deplete the 4400 mAh faster.

Does the battery get hot or draw extra power during all-day use?

The built-in smart control chip manages charging current and provides overheat protection, helping keep temperature and power consumption within safe limits.

Which original Asus part numbers must match for this replacement to work?

It replaces Asus part numbers A32-K55, A32-K55X, A33-K55 and A41-K55; verify your original battery carries one of these codes.
