Replacement Battery for Asus K55 and X75 Series

This 6-cell lithium-ion pack is a direct replacement for a wide range of Asus laptops including the K55, K75, X75, A45, A55, A75, R400, R500, R700 and U57 models. It matches the original A32-K55, A33-K55 and A41-K55 part numbers and supplies 10.8V at 4400mAh for 48Wh of capacity.

Simple Swap with Built-in Protection

The battery fits the existing bay without tools and uses the stock latch mechanism. A smart control chip manages charging current, provides short-circuit, overheat and overload safeguards, and helps extend discharge time. Verify your original battery part number and output voltage before fitting to avoid mismatches.

48Wh for Everyday Mobility

The 4400mAh rating delivers several hours of typical office work or web browsing on a full charge. Runtime falls off under heavy loads such as gaming or video rendering, and capacity will gradually reduce after repeated cycles. It is not suited for users who need all-day operation away from a power outlet.
