Dr. Battery 6-Cell Lithium-Ion Replacement

This 10.8V 4400mAh battery replaces original Asus packs such as A32-K55, A33-K55 and A41-K55. It suits owners of listed Asus A, F, K, P, R, U and X series laptops who need a fresh power source. The unit is new and built with professional grade cells.

Verify model number voltage and connector

Before ordering, confirm your laptop model appears in the compatibility list and that your original battery part number matches one of the referenced codes. Check that the original output voltage reads 10.8V to avoid a mismatch. The supplier advises comparing the physical battery before purchase.

Smart chip manages sustained discharge

A built-in control chip regulates charging current and protects against short circuit, overheat and overload during extended use. The 48Wh capacity delivers steady run time for daily workloads rather than brief bursts. Cells maintain OEM specification levels across repeated cycles.

Questions about this item

Does the battery ship with any cables or tools, or is it just the battery itself?

Only the 6-cell lithium-ion battery is included; no cables, tools or adapters come in the box.

Yes, the MPL03238P-17 lists A32-K55X among its compatible original part numbers.

What does the 4400 mAh rating mean for daily runtime on my Asus X75?
