Replacement battery for Acer Aspire series

The Dr. Battery MPL01217P-21 is a new 6-cell lithium-ion unit rated at 10.8V and 4400 mAh. It replaces original Acer batteries such as AS01B41, AS10B31, AS10B41 and AK.006BT.082. Designed for owners of compatible Aspire models who need a direct swap for a worn-out pack.

Verify model and voltage before ordering

Check the part number printed on your original battery against the compatibility list that includes Aspire 4553, 4745, 4820, 5553, 5625, 5745, 5820, 7250, 7739 and 7745 variants. Confirm the existing pack reads 10.8V; a different voltage means this unit will not work.

Suits users replacing a failed 6-cell pack

Ideal for anyone restoring runtime to a listed Aspire notebook without modifying the chassis. Not for owners of laptops outside the listed model range, machines that require a 9-cell or 12-cell form factor, or systems needing a different voltage or connector layout.
