Replacement battery for Acer Aspire M3 and M5
This 11.1V, 54Wh unit replaces part numbers AP12A3i, AP12A4i, 3ICP7/67/90, KT.00303.002 and BT.00304.011. It fits Acer Aspire M3 Series, Timeline Ultra M3 Series, Aspire M5 Series and Timeline Ultra M5 Series models including the M5-481, M5-481T, M5-481PT and M5-581T. Buyers whose laptops use a different battery connector or form factor cannot use this pack.
Sustained discharge at 11.1V
The 54Wh capacity is rated for continuous delivery at the nominal voltage during typical workloads. Internal cell balancing supports steady output across the discharge curve rather than only in short bursts. Runtime varies with system power draw, screen brightness and background tasks, so exact hours are not fixed by the battery alone.
Thermals, noise and power draw
The pack operates silently with no moving parts and generates minimal heat during normal charge and discharge cycles. Power draw from the wall depends on the laptop’s own charger efficiency and power-management settings, not on the battery itself. Avoid exposing the unit to extreme temperatures to preserve long-term capacity.
