Replacement battery for Swift and Cloudbook

The Beisite AP16A4K is a new lithium-ion battery built for Acer Swift 1 SF113-31 and Aspire One Cloudbook 11 AO1-132 series laptops. It restores mobile power for owners whose original pack no longer holds a useful charge. The 42Wh cell matches the factory voltage of 11.25V and replaces part numbers AP16A4K, KT.00304.003, KT.00304.007 and 3ICP4/68/111.

Black hard-shell pack with direct-fit connector

The black enclosure uses the same mounting points and connector layout as the original battery, so installation follows the laptop's standard service procedure without adapters or cable modifications. A 12-month warranty covers defects in materials and workmanship for the replacement unit.

Low heat output under normal loads

Lithium-ion chemistry keeps thermal output modest during typical office workloads, and the pack draws no power when the system is off or asleep. The 42Wh capacity supports several hours of light use per full cycle, though runtime varies with screen brightness, wireless activity and background tasks.

Questions about this item

What voltage does the 11.25V lithium-ion battery deliver to the Swift 1 SF113-31?

The battery supplies a nominal 11.25V to the laptop's power rail, matching the original specification for the Swift 1 and Cloudbook 11 series.

Which screw-hole pattern and connector does the 3ICP4/68/111 pack use to fit the AO1-132 chassis?

The pack is built to the original 3ICP4/68/111 form factor, so its mounting holes and multi-pin connector align with the Swift 1 SF113-31 and Cloudbook 11 AO1-132 battery bays.

What is the first step when installing the AP16A4K battery, and what do people often skip?

Power off the laptop, unplug the AC adapter, then disconnect the old battery cable before removing any screws; skipping the cable disconnect risks a short circuit.
