Replacement battery for Acer Aspire

This 6-cell lithium-ion unit replaces the original pack in a wide range of Acer Aspire and Gateway notebooks. It delivers 11.1 V and 4400 mAh for 49 Wh of capacity. The pack is new and built to match OEM specifications. It suits owners of the listed models who need a direct swap.

Sustained discharge with smart-chip protection

An integrated control chip manages charge and discharge cycles to reduce power consumption and extend run time per session. Built-in safeguards guard against short circuit, overheating and overload during continuous use. The cell chemistry maintains stable voltage across the discharge curve. Users can rely on consistent output for everyday workloads.

11.1 V 4400 mAh capacity decides fit

The 11.1 V 4400 mAh rating must match the original battery label exactly for the laptop to recognise and charge the pack correctly. A different voltage or capacity will cause charging errors or reduced run time. Verify the part numbers AS07B31, AS07B41, AS07B51 or AS07B61 before ordering. Buyers whose original battery shows different values cannot use this unit.
