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.

Questions about this item
How long will the 2200 mAh capacity actually run a Dell Inspiron 14 3421 under typical office use?
The 2200 mAh rating at 14.8 V gives 32 Wh of stored energy. Real runtime depends on screen brightness, CPU load and Wi-Fi activity, so expect roughly three to five hours for light productivity tasks.
What connector standard does the MPL05283P-27 use and does it limit charging speed?
The pack uses the proprietary Dell slide-in connector that matches the original 0MF69, 24DRM and 312-1387 part numbers. It carries the same 14.8 V rail, so the laptop’s own charge controller sets the current limit.
Will the four-cell black pack fit the battery bay of a Dell Inspiron 15R 5521 without modification?
Yes. The MPL05283P-27 is built to the exact dimensions of the Dell 4-cell module used in the 15R 5521, 15 3542 and 17 5748, so it drops into the existing bay and locks with the original latches.
