Dr. Battery MPL03249P-01 4-cell 14.4V 2200mAh laptop battery

Replacement battery for Asus A450 F550 K550 series

This Dr. Battery unit replaces the original pack in Asus A450 A550 F450 F550 F550C F550LA F550V F552 F552C K450 K450CA K450L K550 K550C K550CA K550L K550LA K550LC K550V K552EA P450 P450C P450CA P450L P550 P550C P550CA models. It is a new four-cell lithium-ion module rated at 14.4V and 2200 mAh. The smart control chip manages charging and protects against short circuit overheat and overload. Buyers who need a higher capacity pack or a different voltage should look elsewhere.

Voltage and capacity determine runtime

The battery delivers 14.4V and 2200 mAh for a total of 32 Wh. That energy figure sets the practical runtime limit for the supported laptops. A lower voltage pack will not power the machine and a higher voltage pack risks damage. The four-cell construction fixes the physical size so the pack fits the original bay. Systems that require a six-cell or nine-cell design cannot use this unit.

Match the original part number before ordering

The critical specification is the exact part number match with your original battery such as 0B110-00230000 0B110-00230100 A41-X550 or A41-X550A. Voltage must read 14.4V and the connector layout must align. If the original label shows a different part number or a different cell count this battery will not fit or function correctly.
