Dr. Battery MPL03243P-08 6 Cell 10.8V 4400mAh laptop battery

Replacement battery for Asus U-series

The Dr. Battery MPL03243P-08 is a new six-cell lithium-ion unit built to replace the original pack in a wide range of Asus U33, U42, U43, U52 and U53 notebooks. It delivers 10.8 V and 4400 mAh (48 Wh) through an integrated smart control chip that manages charging and discharge cycles. The design targets owners of those specific models who need a direct swap without modification.

4400 mAh capacity and runtime limits

At 4400 mAh the pack restores the factory-rated energy budget, so typical office workloads, web browsing and video playback run for the same duration as when the laptop was new. Heavier loads such as sustained compilation, gaming or external GPU use will drain the cells faster, and the single pack cannot be extended without a second battery or mains power.

Fits Asus U33, U42, U43, U52, U53 chassis

The battery matches the original form factor and voltage, so it seats in the existing bay and connects to the stock connector without adapters. No BIOS update or driver install is required; the smart chip communicates with the laptop’s power manager immediately. Buyers who need higher capacity, a different voltage or compatibility outside the listed Asus models must look elsewhere.
