What this battery replaces

This Dr. Battery MPL05216P-28 is a six-cell lithium-ion pack rated at 11.1V and 4400 mAh. It matches the original Dell part numbers 0WK380, 0WK381, 0WP193 and 0X284G for Inspiron 14 1440, 15 1525, 15 1526, 15 1545, 1546 and 17 1750 models as well as Vostro 500. Buyers who need a higher capacity than 49 Wh or a different voltage should look elsewhere.

Behaviour under sustained load

The pack uses professional-grade cells that meet OEM specification levels and include a smart control chip for lower power consumption and longer discharge time. Built-in protections guard against short circuit, overheat and overload during continuous use. Capacity remains at 4400 mAh across the full cycle rather than peaking only in short bursts.

Installation and common issues

The battery fits the listed Dell chassis without modification, but you must verify the exact model number and original part number before fitting. A mismatch in voltage or connector layout is the most frequent cause of a failed install. The unit ships new with a one-year warranty and includes no tools or adhesives.

Questions about this item

Does the 6-cell 11.1V design run hotter than the original 4-cell pack during all-day use?

The lithium-ion cells and smart control chip manage heat and power consumption to OEM levels, so sustained operation stays within the thermal envelope Dell engineered for the chassis.

My Dell Vostro 500 uses part number 0WK380 — will this MPL05216P-28 fit without an adapter?

Yes, the battery replaces 0WK380, 0WK381, 0WP193 and the other listed OEM numbers directly; it slides into the same bay and connects to the existing motherboard header.

Will the 4400mAh capacity work correctly with the charging circuit in my Inspiron 1525?

The built-in smart chip communicates with the laptop’s original charging logic, enabling normal charge cycles, short-circuit protection and accurate fuel-gauge reporting.
