Compatible Acer Models

This replacement battery fits the Acer Predator Triton 300 SE PT314-51s series, the Swift Edge SFX16-61G series and the Swift X 14 SFX14-71G series. It is a direct replacement for part number AP21B7Q. Owners of other Acer lines or different part numbers should verify compatibility before purchasing.

The 76WH lithium-ion cell delivers 4930mAh at 15.48V, providing consistent energy for extended work or gaming sessions. Internal protection circuits manage charge cycles to maintain stable output over the battery’s lifespan. Users needing longer runtime than the original pack supplied may find this capacity insufficient.

The black Li-ion pack uses cells manufactured in China under a high-quality guarantee and ships in new condition. Its proprietary connector aligns with the factory battery bay for a secure fit without adapters. Builders upgrading chassis designs that require a different form factor cannot use this unit.

Questions about this item

Does the 15.48V 76WH Li-ion battery run hotter than the original after hours of gaming on the Predator Triton 300 SE?

It matches the factory 15.48V 76WH specification, so thermal behaviour stays the same as the original pack under sustained load.

What must I already own to install the AP21B7Q in my Swift X 14 SFX14-71G?

Only a small Phillips screwdriver to remove the bottom cover and disconnect the old pack; no extra cables or adapters are required.

Will the 4930mAh replacement charge correctly through the existing USB-C PD port on my Swift Edge SFX16-61G?

Yes — the cell voltage and connector are identical to the OEM unit, so the laptop’s built-in charger manages it normally.
