Replacement battery for Asus U-series laptops

The Dr. Battery MPL03243P-16 is a new 6-cell lithium-ion pack rated at 10.8V and 4400 mAh. It replaces Asus part numbers A31-U53, A32-U53, A41-U53 and A42-U53 across the U33, U42, U43, U52 and U53 model families. Buyers who need a higher-capacity pack or a different voltage should look elsewhere.

Straightforward swap with built-in protection

The battery fits the original bay and connects to the existing socket without tools. A smart control chip manages charging, provides short-circuit, overheat and overload protection, and aims to extend discharge time. The most common issue is ordering the wrong part number, so verify the label on your old battery before fitting the new one.

Check model, part number and voltage first

Confirm your laptop appears in the compatibility list and that the original battery shows 10.8V and the Asus part numbers above. The pack carries a one-year warranty from 2020 manufacture. If your machine uses a different voltage or connector, this unit will not work.

Questions about this item

How can I confirm the 6-cell 10.8V 4400mAh battery is working correctly after installation?

The operating system should report the full 4400 mAh design capacity and 10.8 V output, and the laptop must run on battery power alone without shutting down.

What is included in the box and do I need to buy anything else for installation?

The package contains the replacement battery only; no tools, screws or adapters are supplied, so have a suitable screwdriver ready if your laptop requires one.

Which Dr. Battery model matches my Asus U53J — the MPL03243P-16 or another part number?

The MPL03243P-16 replaces Asus part numbers A31-U53, A32-U53, A41-U53 and A42-U53, so match the code printed on your original battery to one of those.
