Dr. Battery MPL05283P-16 4-cell 14.8V 2200mAh laptop battery

Direct replacement for Dell Inspiron and Vostro

This Dr. Battery MPL05283P-16 unit replaces the original pack in Dell Inspiron 14, 15 and 17 models from the 3421 to 5748 series plus Vostro 2421, 2521, 3445, 3446, 3449, 3546 and 3549. It is a new 4-cell lithium-ion battery rated at 14.8V and 2200 mAh. Buyers needing a different voltage or a higher cell count cannot use this pack.

Black 4-cell lithium-ion housing

The black enclosure holds four lithium-ion cells and an integrated smart control chip that manages charging current and discharge timing. Built-in safeguards provide short-circuit, overheat and overload protection during daily use. The form factor matches the OEM footprint so the pack seats in the existing bay without adapters or case modifications.

32 Wh capacity limits runtime on larger 17-inch

At 32 Wh the pack supplies modest energy reserves; a 17-inch Inspiron 3721 or 5748 will drain it faster than a 14-inch 3421 under identical workloads. The 14.8V output is fixed, so systems expecting a different voltage will not recognise the battery. Users who need all-day operation away from mains power should plan for a second pack or a higher-capacity alternative.
