Dr. Battery MPL03243P-03 6 Cell 10.8V 4400mAh
This new replacement battery fits a wide range of Asus laptops including U33, U42, U43, U52 and U53 series models. It uses six lithium-ion cells rated at 10.8V and 4400mAh to restore original runtime. The pack includes a built-in smart control chip for charging management and safety protections against short circuit, overheat and overload. It is intended for owners of compatible Asus notebooks whose original battery no longer holds a useful charge.
Replaces Asus A31-U53 A32-U53 A41-U53 A42-U53
The unit replaces Asus original batteries with part numbers A31-U53, A32-U53, A41-U53 and A42-U53 across the listed U-series models. A jump is worth it when the existing pack drains quickly, shuts down under load or shows physical swelling. The 48Wh capacity matches the OEM specification so runtime returns to factory levels rather than exceeding them. Buyers who need longer life than the original design provided will not gain extra capacity from this model.
Check model number voltage
Confirm your laptop model appears in the compatibility list covering U33, U42, U43, U52 and U53 variants. Verify the original battery part number matches one of the Asus codes above and that the output voltage reads 10.8V. Ensure the connector layout on your current pack lines up with the replacement photos. Systems outside the listed series or with a different voltage will not work with this battery.

Questions about this item
What battery bay and latch style does the 6-cell 10.8V pack use on Asus U42 and U52 series?
The battery slides into the bottom bay and locks with the spring-loaded latch; align the contacts, push until the latch clicks, then confirm the charge LED lights.
What is the correct first-charge procedure for the 4400mAh Li-ion unit?
Power off the laptop, insert the battery until the latch clicks, attach the AC adapter and charge fully before first use; the built-in smart chip manages the cycle.
When should the 48Wh pack be replaced and how is it removed?
Replace when runtime drops below half of new capacity; power off, slide the release latch, lift the pack out, and insert the new unit until it clicks.
