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.
