Replacement battery for Acer Aspire and Nitro models

The FOCUSTEC AC14B8K is a 48WH lithium-ion pack rated at 15.2V across three cells. It replaces part numbers AC14B8K, KT.0040G.004, KT0030G.004, 4ICP5/57/80 and 3ICP5/57/80 in a wide range of Acer Chromebook, Aspire, Nitro 5 and Swift 3 laptops. The unit ships new from the manufacturer with two screwdrivers included for installation.

Steady discharge with built-in protection circuits

Overcharge, overdischarge, over-temperature and short-circuit protection circuits regulate the pack during extended use. The cells are rated for up to 1000 recharge cycles over the life of the battery, supporting consistent capacity through daily charge and discharge routines. The 48WH rating delivers the same energy budget as the original pack for comparable run time.

Black polymer housing with screw-access mounting

The black casing matches the original form factor and secures with the existing screw points on supported chassis. Two free screwdrivers are supplied so the swap can be completed without sourcing extra tools. The connector aligns with the motherboard header on all listed models for a direct fit.

Questions about this item

Does the 15.2V 48WH lithium-polymer battery run hot or draw extra power during all-day use?

The 3-cell 15.2V 48WH pack includes over-temperature protection and overcharge/overdischarge circuits that limit heat build-up and unnecessary power draw during extended operation.

What must my Acer laptop already have for this AC14B8K battery to fit and work?

Your device must be one of the listed Acer Chromebook CB5-571, CB3-531, Aspire R3-131T, R5-471T, R5-571T, R7-371T, Aspire 5 A515-51, Nitro 5 AN515-51/52/53 or Swift 3 SF314-51/52 models using the original AC14B8K, KT.0040G.004, KT0030G.004, 4ICP5/57/80 or 3ICP5/57/80 part.

Will the two included screwdrivers let me swap this 3-cell pack into an older Acer chassis that used a different battery?

The screwdrivers are supplied for the models listed above; if your older chassis is not in that compatibility list the physical fit and connector alignment cannot be guaranteed.
