Replacement Battery for Acer Swift 3 SF315-52 Series

This lithium-ion replacement battery is built for the Acer Swift 3 SF315-52 series, matching part numbers KT.0040G.012 and AC17B8K. It serves owners of compatible models such as the SF315-52-83WQ and SF315-52G-87Y2 who need a direct substitute for the original pack. The unit is new and carries CE, RoHS, ISO9001, UN38.3 and MSDS certifications.

Sustained Operation with Built-In Safeguards

The cell delivers 15.2V and a rated capacity of 3150mAh (47.88Wh) for extended runtime during continuous use. Integrated protection circuits guard against overcharge, over-discharge, over-voltage and short-circuit conditions, helping maintain stable output over long sessions. Physical dimensions of 201.1 x 176.6 x 5.6mm and a weight of 473.6g ensure a precise fit inside the chassis.

Direct Swap for Worn Original Packs

This battery replaces the factory-installed unit when it no longer holds sufficient charge or shows swelling. The upgrade is worth it when the laptop shuts down unexpectedly, reports reduced capacity or fails to run unplugged for a usable period. Buyers who need a different voltage, capacity or form factor for another laptop series should look elsewhere.

Questions about this item

How much heat does the 15.2V 3150mAh battery generate during all-day use?

The lithium cell produces minimal heat under normal loads; its built-in over-voltage and short-circuit protection keeps temperatures stable during extended sessions.

What must I already own to install this 201.1 x 176.6 x 5.6mm replacement?

You need a compatible Acer Swift 3 SF315-52 series laptop and a small Phillips screwdriver to open the bottom case and swap the pack.

Will this 47.88Wh pack work alongside the original AC17B8K charger I kept?

Yes, the voltage and connector match the original KT.0040G.012 specification, so your existing charger will charge the new battery normally.
