Direct replacement for listed Asus models

This 6-cell lithium-ion pack is built to match the original 10.8V 4400mAh specification for a long list of Asus laptops including the F75VD, K55 series, X75 series and R400, R500, R700 lines. It is a new component intended for owners whose factory battery no longer holds a useful charge.

Six cells in a black housing with smart protection

The brick-shaped unit uses six lithium-ion cells and an integrated control chip that manages charging current, discharge rate and thermal limits. Built-in safeguards cut power on short circuit, overheat or overload events, helping protect both the battery and the notebook during daily use.

Limited to 10.8V systems with matching part numbers

Capacity is fixed at 4400mAh or 48Wh, so runtime will mirror the original pack rather than extend it. The battery only fits models that accept the A32-K55, A33-K55 or A41-K55 form factor and voltage; machines requiring a different voltage, cell count or physical layout cannot use it.
