Dr. Battery MPL01231P-08 replacement

This 2200 mAh lithium polymer battery replaces the original pack in compatible Acer Aspire, Chromebook, ES1 and V3 models. It delivers 15.2 V and 33 Wh through an integrated smart control chip that manages charging and discharge cycles. The unit is supplied new and carries a one-year warranty from the manufacturer. It suits owners who need a direct swap without modifying the chassis.

Upgrade from a depleted original

The battery restores runtime lost to cell ageing in machines such as the Acer Chromebook 11 C730, 13 C810 or 15 C910 and the Aspire E5-771 series. A jump is worth it when the original pack no longer holds a useful charge or shows swelling. It will not suit buyers who need a higher-capacity pack than the factory specification.

Sustained load behaviour

The smart control chip regulates output during extended sessions, providing short-circuit, overheat and overload protections that keep voltage stable under continuous draw. Cells are built to OEM specification so discharge curves remain consistent over repeated cycles. The design targets reliable performance for daily mobile workloads rather than short bursts.

Questions about this item

Will the 15.2 V lithium-polymer pack fit the battery bay of my Acer Aspire E5-771G?

The pack is built to the original dimensions for every model listed, including the E5-771G, so it seats in the existing bay without modification.

Which screw or latch do I release first when swapping the battery on an Acer Chromebook 13 C810?

Remove the bottom case screws, lift the cover, disconnect the old pack’s cable, then connect the new pack before refitting the cover — skipping the cable step is the common error.

How often should I run a full charge cycle to keep the 33 Wh cells healthy?

A full discharge and recharge once every 30 days calibrates the smart chip and preserves capacity over the one-year warranty period.
