Replacement battery for Acer Chromebook 512 C852

This KingSener AP20CBL lithium-ion battery delivers 11.55V and 4590mAh (53WH) capacity. It replaces part numbers AP20CBL, KT.0030B.002 and 31CP5/82/70. The pack is designed for Acer TravelMate Spin B3 TMB311RNA, Swift 3 SF314-43 and SF314-511, Aspire 5 A515-46 and Chromebook 315 CB315-4H models.

Straightforward swap with basic tools

Installation requires removing the bottom case screws and disconnecting the old pack connector before fitting the new unit. Common issues include forgetting to detach the battery cable before unscrewing the board, which can damage the header, and not reseating the connector fully, leading to a no-power condition.

Verify exact model and voltage before ordering

Confirm your laptop's service tag matches one of the listed series such as C852, TMB311RNA, SF314-43, SF314-511, A515-46 or CB315-4H. Ensure the original battery shows 11.55V and the same physical layout; units with different voltage or connector pin-out will not work.
