Replacement Battery for Acer Chromebook C720

This 45Wh lithium-polymer unit replaces part numbers AP13J3K and AP13J4K across a wide range of Acer Chromebook C720, C720P and C740 models. It restores mobile power to devices where the original cell has degraded or failed.

11.25V Li-polymer chemistry limits

The pack delivers 11.25 volts and 3990mAh capacity using Li-polymer cells, matching the factory voltage specification. Runtime scales with the original design envelope and cannot exceed the platform's power-management ceiling.

Upgrade from worn original cells

Swapping a depleted stock battery for this new 45Wh unit recovers full unplugged runtime without changing the chassis or charger. The jump is worth it when the old pack holds less than half its rated charge or triggers sudden shutdowns.
