Dr. Battery MPL03230P-19 6-cell 4400mAh 10.8V laptop battery

Replacement battery for Asus A54C K53 series

The Dr. Battery MPL03230P-19 is a new 6-cell lithium-ion pack built to match OEM specifications for a wide range of Asus notebooks including the A43 A53 A54 K43 K53 X43 X53 and P43 families. It serves owners who need a direct drop-in replacement for original part numbers such as A31-K53 A32-K53 A41-K53 A42-K53 90-N3V3B1000Y and 07G016JE1875. Buyers with laptops outside the listed compatibility table should look elsewhere.

4400 mAh 10.8 V capacity and runtime headroom

Rated at 4400 mAh and 48 Wh the pack delivers the same voltage and capacity as the factory battery it replaces. It comfortably powers typical office web browsing and media playback sessions for several hours. Runtime will fall short for users who run sustained heavy workloads such as video rendering or gaming on battery alone.

Smart-chip protection thermals and power draw

A built-in smart control chip manages charging current to reduce heat buildup and extend cycle life. The circuitry provides short-circuit overheat and overload safeguards that keep the pack within safe thermal limits during normal charging and discharge. Power draw follows standard laptop regulation with no unusual acoustic or thermal signature.
