Dr. Battery MPL01223P-15 laptop battery 4 cell 14.8V 2200mAh 33Wh

Dr. Battery 4-cell 14.8V replacement

The Dr. Battery MPL01223P-15 is a new 4-cell lithium-ion unit rated at 14.8V and 2200mAh for 33Wh. It targets owners of compatible Acer Aspire models who need a direct replacement for a depleted or failing original pack.

Practical limits of a 4-cell lithium-ion pack

A 4-cell design at 14.8V delivers a fixed energy capacity of 33Wh, so runtime scales directly with the laptop's power draw and cannot be extended without a higher-capacity alternative. The built-in smart control chip manages charging current and provides short-circuit, overheat and overload protection, but it does not alter the fundamental voltage or watt-hour ceiling of the chemistry.

Verify model number and original battery code

Before ordering, confirm that your laptop appears in the listed Acer Aspire E1 series range and cross-reference the original battery part numbers such as AK.004BT.097, AL12A32, AL12A72, B053R015-0002, KT.00403.012 or TZ41R1122. Buyers whose device uses a different voltage, cell count or connector layout will find this pack incompatible.
