Dr. Battery MPL03238P-16 replacement

This Dr. Battery MPL03238P-16 is a new 6-cell lithium-ion laptop battery rated at 10.8V and 4400mAh. It serves as a direct replacement for a wide range of Asus models including the X75, A55, K55, F55 and R500 series. The pack restores mobility to notebooks whose original cells no longer hold a useful charge.

Upgrading from a depleted original pack

The battery replaces OEM part numbers such as A32-K55, A32-K55X, A33-K55 and A41-K55. The jump is worth it when the existing pack drops to a fraction of its rated runtime or triggers shutdowns under load. A built-in smart control chip manages charging and provides short-circuit, overheat and overload protection. Buyers who need a higher-capacity pack or a different form factor should look elsewhere.

Sustained discharge with protection active

Under continuous use the 48Wh pack delivers steady voltage while the protection circuits monitor temperature and current. The smart chip balances cell charge to extend overall service life and reduce power draw during idle periods. The design targets reliable performance across the full discharge cycle rather than a brief peak. Users who require hot-swap capability or external charging docks will not find those features here.

Questions about this item

Will the MPL03238P-16 fit my Asus X75A without modification?

Yes, this 6-cell 10.8V pack is built to match the original A32-K55 form factor and locks into the same bay on X75A, X75V, X75VC and X75VD models.

What is the correct way to seat the battery so the latch engages?

Slide the pack in until both side rails click, then press the release latch once to confirm it is locked; the common mistake is stopping at the first click and leaving the rear edge raised.

When should I replace the 4400mAh pack if runtime keeps shrinking?

Replace it when a full charge lasts less than half the original runtime or the laptop shuts down suddenly above 20% indicated charge.
