Dr. Battery MPL03238P-20 replacement

This 6-cell lithium-ion pack replaces the original Asus A32-K55 series battery for models such as the R700, U57, X45, X75, A45, A55, A75, F45, K45 and K55 families. It delivers 10.8V and 4400mAh capacity for users who need a direct-fit spare.

Voltage and capacity limits

The 10.8V output and 4400mAh rating define the energy envelope; the pack cannot exceed the original design voltage or runtime. Builders must match both figures exactly or the laptop will not recognise the pack.

Six-cell lithium-ion configuration

The six-cell layout determines physical thickness and connector placement, so the battery only fits chassis designed for the A32-K55 form factor. Buyers with slimmer ultraportables or models using 3-cell packs cannot use this unit.
