Dr. Battery MPL01204P-28 6-cell 11.1V 4400mAh laptop battery

Direct replacement for Acer Aspire series

This 6-cell lithium-ion battery operates at 11.1V with a 4400mAh capacity delivering 49Wh of energy. It is built to match OEM specifications for a wide range of Acer Aspire models including the 2430, 2930, 4220, 4230, 4235, 4240, 4310, 4315, 4320, 4330, 4332, 4336, 4520, 4530, 4535, 4535G, 4540, 4540G, 4710, 4715, 4720, and 4730 series. The black housing integrates a smart control chip that manages charging and discharge cycles.

Upgrades worn or failed original packs

It replaces original Acer batteries carrying part numbers such as BT.00607.012, BT.00607.013, BT.00607.014, BT.00607.015, BT.00607.019, BT.00607.020, and BTP-AS4520G. The jump is worth it when the original pack no longer holds a useful charge, swells, or triggers a replacement warning in the BIOS. A fresh 49Wh cell restores the runtime the laptop was designed for without changing the voltage or form factor.

Simple user installation with built-in safeguards

The pack fits into the standard battery bay on the underside of the compatible Aspire chassis; no tools are required beyond the release latch. Built-in protection guards against short circuit, overheat, and overload during operation. The most common issue is ordering the wrong voltage or connector, so verify the model number and 11.1V rating on the original battery before purchase.
