Replacement Battery for Dell Inspiron Laptops

The Dr. Battery MPL05271P-22 is a new six-cell lithium-ion pack rated at 11.1V and 4400mAh. It replaces a long list of Dell part numbers including 0MF69, 24DRM, 312-1387, 312-1390, 312-1392, 312-1433 and 451-12107. The unit is aimed at owners of compatible Inspiron 14, 15 and 17 models who need a direct swap for a worn original.

Black Six-Cell Housing

The black casing matches the OEM form factor for the supported Inspiron 3421, 3437, 3442, 3521, 3531, 3541, 3542, 3543, 3721, 5421, 5521, 5537, 5721, 5737, 5748 and 5749 series. A built-in smart control chip manages charging, provides short-circuit, overheat and overload safeguards, and is designed to deliver longer discharge time per cycle.

Verify Model, Original Part Number

Dell used several different batteries across the Inspiron 14, 15 and 17 families, so the part number on your old pack must match one of the listed codes. Confirm the original battery shows 11.1V output and a six-cell layout. This product will not suit systems that require a different cell count, voltage or physical shape.
