Replacement Battery for Dell Inspiron 14 15 17

This Dr. Battery MPL05283P-27 is a new four-cell lithium-ion unit built to match OEM specifications for a wide range of Dell Inspiron laptops. It fits models including the 14-inch 3421, 3437 and 3442, the 15-inch 3521, 3531, 3541, 3542 and 3543, and the 17-inch 3721, 3737 and 5748. The black casing and original form factor allow a direct swap without modifications.

14.8 V 2200 mAh 32 Wh capacity match

The single specification that decides fit is the electrical rating: 14.8 volts and 2200 milliampere-hours delivering 32 watt-hours. Your original battery must show the same voltage and a comparable capacity; a different voltage will prevent the laptop from charging or powering on correctly. Verify the part numbers listed such as T1G4M, V1YJ7, 0MF69, 24DRM, 312-1387, 312-1390 or 312-1392 before ordering.

Built-in smart chip with protection circuits

The integrated control chip manages charging current to reduce heat and extend discharge time. It also provides short-circuit, overheat and overload safeguards that protect both the battery cells and the laptop's power circuitry during daily use. No extra software or drivers are required; the battery communicates with the system through the standard Dell battery interface.
