Replacement Battery for Acer Nitro V 15

This 15.4V lithium-ion battery delivers 57.48Wh of capacity and fits Acer Nitro V 15 ANV15-51 series laptops. It replaces part number AP21D8M and matches models including AN515-58-74JS, AN515-58-75UH and AN515-58-77YC. Buyers needing a different voltage or form factor should look elsewhere.

Steady Capacity Through a Work Session

The 3733mAh cell maintains its rated 57.48Wh during extended use rather than only in brief bursts. Internal protection circuitry manages charge and discharge cycles to keep output stable while you work or game. The pack is not designed for user-serviceable cell replacement.

Direct Fit With No Soldering Required

Installation uses the original battery connector and mounting points, so no tools beyond a screwdriver are needed. Common issues arise when the battery lock latch is not fully engaged or when the BIOS is not reset after the swap. Verify the part number AP21D8M on your old unit before fitting.

Questions about this item

How much heat does the 15.4V 57.48WH battery generate during extended use?

Li-ion cells in this pack run cool under normal loads; heat stays within typical laptop-battery limits.

Must my Acer Nitro V 15 AN515-58 already have the original AP21D8M part installed for this replacement to fit?

Yes — the AP21D8M is a direct replacement for that exact part number in the listed AN515-58 models.

Will this 15.4V replacement work alongside the original charging circuit in an older AN515-58 unit?

The voltage matches the factory spec, so the existing charging system recognises and manages it normally.
