37 Wh replacement battery

This lithium-polymer pack delivers 14.8 V and 37 Wh of capacity for Acer Aspire One 725 and 756 notebooks. It replaces part numbers AL12B32, AL12X32, AL12A31 and AL12B31. The black unit ships brand new and fits the V5-131 and V5-171 series as well.

Capacity and daily runtime

At 2500 mAh the cell provides enough energy for typical office tasks and web browsing on these ultraportable models. Runtime will fall off quickly under sustained CPU load or when driving an external display. It is not suited for users who need all-day operation away from mains power.

Upgrade path and fit

The battery directly substitutes the original equipment in the listed Aspire One and V5 chassis. Owners of other Acer models or those requiring higher watt-hour ratings should look elsewhere, as this pack does not extend beyond the 37 Wh specification.

Questions about this item

Will the 14.8V 37Wh AL12B32 battery power my Aspire One 725 alongside the original AC adapter?

Yes, the 14.8V 37Wh pack replaces AL12B32, AL12X32, AL12A31 and AL12B31 and fits the Aspire One 725, so it works with the existing charger.

How can I verify the 2500mAh Li-polymer cell is charging correctly after installation?

The battery LED on the Aspire One 725 or 756 will show the normal charge indicator once the 14.8V 37Wh unit is seated and the AC adapter is connected.

Does the AL12B32 package include screws or tools for the V5-131 and V5-171 models?

Only the 37Wh 14.8V battery itself is supplied; mounting screws and any opening tools must be sourced separately.
