54Wh Li-polymer battery for Acer Aspire M3 and M5

This 11.1V lithium-polymer battery delivers 54Wh of energy with a 4850mAh cell rating. It is built as a direct replacement for the AP12A3I part number used across several Aspire models. The unit arrives in new condition and is ready for immediate installation.

Black polymer housing with integrated connector

The black casing matches the original chassis colour and uses the factory connector layout for a secure fit. No soldering or adapter cables are required during the swap. The polymer chemistry keeps the pack slim while maintaining stable voltage output under load.

Replaces worn AP12A3I packs in M3-581TG M5-481

When the original battery no longer holds a full charge this unit restores the runtime the laptop was designed for. The upgrade is worthwhile once the old pack drops below usable capacity or shows swelling. Buyers needing a higher-capacity alternative or a different voltage should look elsewhere.
