Replacement battery for Acer Swift 1

This lithium-polymer battery replaces the original AP16A4K unit in Acer Swift 1 SF113-31 and Aspire One Cloudbook 11 AO1-132 series notebooks. It delivers 11.25V and 42Wh capacity using Grade-A cells. The pack carries CE, FCC and RoHS certifications for safety and environmental compliance.

Suits owners matching the part number.

Installers who confirm their original battery carries part number AP16A4K, KT.00304.003, KT.00304.007 or 3ICP4/68/111 will find a direct fit. Buyers whose laptop uses a different part number or connector layout should look elsewhere because this pack will not mate with their system.

11.25V 42Wh 3770mAh capacity decides fit

The voltage and watt-hour rating must match the original battery exactly or the notebook will not charge or report capacity correctly. Verify the 11.25V and 42Wh figures on the old battery label before ordering.

Questions about this item

Which original battery part number must I verify on my Acer Swift 1 SF113-31 before ordering this AP16A4K replacement?

Confirm your existing battery shows AP16A4K, KT.00304.003, KT.00304.007 or 3ICP4/68/111 on its label; only those part numbers guarantee a correct fit.

Will the 11.25V 42Wh rating match the power profile of my Aspire One Cloudbook 11 AO1-132 without BIOS changes?

Yes, the replacement delivers the same 11.25V voltage and 42Wh capacity as the factory battery, so the notebook’s power management recognises it immediately.

After installing the battery, how do I confirm the 3770mAh cells are charging to full capacity?

Discharge to 5%, then charge to 100% and repeat three to four cycles; the operating system should then report the full 42Wh design capacity.
