Dr. Battery MPL05216P-29 6-cell 4400 mAh 11.1 V laptop battery

Replacement battery for Dell Inspiron and Vostro

The Dr. Battery MPL05216P-29 is a 6-cell lithium-ion unit rated at 11.1 V and 4400 mAh, delivering 49 Wh. It replaces original part numbers such as 0C139H, 0C601H, 0CR693 and 0GW240. The pack is built for Dell Inspiron 14 1440, 15 1525, 15 1526, 15 1545, 1546 and 17 1750 models, plus Vostro 500.

Voltage and capacity define the practical limits

The 11.1 V output must match the original battery exactly; a different voltage will prevent the laptop from starting or charging. Capacity of 4400 mAh determines run time, so heavier workloads will drain the pack faster than the original higher-capacity units. The smart control chip manages charge cycles and protects against short circuit, overheat and overload, but it cannot increase the fundamental energy stored in the six cells.

Simple swap if the part number matches

Installation requires removing the old pack and sliding this unit into the same bay until the latch clicks. The most common issue is ordering the wrong variant — always compare the original part number and the 11.1 V label before purchase. If the laptop does not recognise the new battery, reseat the connector and allow a full charge cycle; persistent recognition faults usually indicate a part-number mismatch rather than a defective cell.
