Replacement battery for Asus X75, K55.

This new 6-cell lithium-ion pack from Dr. Battery replaces original part numbers A32-K55, A32-K55X, A33-K55 and A41-K55. It fits Asus X75, X75A, X75V, X75VC, X75VD, A45, A55, A75, F45, F45A, F75A, F75VD, K45, K55, K55A, K55N, K55VD, K75, P45VJ, R400, R500, R700, U57, X45 and related models. Buyers who need a battery for a different laptop family should look elsewhere.

10.8 V output matches the original specification

The pack delivers exactly 10.8 V, the same voltage Asus specifies for the listed models. A built-in smart control chip manages charging to keep the voltage stable and protects against short circuit, overheat and overload conditions. Using a battery with a different voltage can damage the laptop or prevent it from starting.

4400 mAh capacity rated for full-day use

At 4400 mAh (48 Wh) the cell set is designed to sustain typical workloads through a working day rather than only short bursts. The smart chip lowers power consumption during extended discharge and supports quicker recharge cycles. Heavy continuous loads such as gaming or video rendering will reduce runtime compared with light office tasks.
