Dr. Battery 4-cell 14.8V replacement
This new Dr. Battery MPL05278P-28 is a 4-cell lithium-ion unit rated at 14.8V and 2200mAh. It serves as a direct replacement for numerous Dell Inspiron 14 and 15 series models including the 3000, 3451, 3551 and 5000 families. The black battery targets owners of those specific laptops who need to restore original runtime.
Sustained discharge with protection circuit
A built-in smart control chip manages the discharge curve to deliver steady voltage under continuous load rather than a brief peak. Integrated safeguards against short circuit, overheat and overload activate automatically during extended sessions to protect both the pack and the notebook. The 33Wh capacity supports typical productivity workloads across a full working day.
Verify model and original part number
Before ordering, match your laptop’s exact model number against the long compatibility list supplied above. Cross-reference the original battery part numbers such as P64G001, VN3N0, WKRJ2, 07G07, 1KFH3, 451-BBMG or 451-BBOO printed on your old pack. Confirm the output voltage reads 14.8V to avoid a mismatch.

Questions about this item
Does the 14.8 V lithium-ion pack run hot or draw extra power during all-day use?
The 4-cell 2200 mAh battery operates at standard laptop voltage and includes built-in overheat and overload protection, so it stays within normal thermal limits during continuous operation.
Must my Dell already have a specific original battery part number for this MPL05278P-28 to fit?
Yes — match your existing battery to one of the listed part numbers such as P64G001, P65G, VN3N0, WKRJ2, 07G07, 1KFH3, 451-BBMG or 451-BBOO before ordering.
Will this replacement work alongside the original Dell AC adapter I keep for my Inspiron 15-3551?
The pack is designed to the same 14.8 V 33 Wh specification as the factory unit, so it charges and discharges normally with your existing Dell charger.
