Dr. Battery MPL03230P-30 6 Cell 10.8V 4400mAh laptop battery

Replacement battery for Asus K and X series

This 6-cell lithium-ion unit replaces original Asus packs such as A31-K53, A32-K53, A41-K53 and A42-K53. It fits a wide range of models including K43, K53, K54, X43, X44 and X53 families. The pack delivers 10.8 V and 4400 mAh for 48 Wh of capacity. Buyers who need a higher-capacity cell or a different voltage should look elsewhere.

Sustained discharge with smart-chip management

A built-in control chip regulates charge current to reduce power consumption and extend discharge time under continuous load. The circuitry maintains stable output during long sessions rather than only in short bursts. Protection against short circuit, overheat and overload activates automatically when limits are reached. Users who require hot-swap capability or external charging docks will not find those features here.

Thermal limits and power draw in normal use

The lithium-ion chemistry and protection circuits keep temperatures within safe margins during typical office or media workloads. No active cooling is required and the pack adds no audible noise to the system. Power draw follows the laptop's own management profile without extra overhead. Buyers expecting a fan-assisted design or a ruggedised enclosure for extreme environments will not be served by this unit.
