Dr. Battery MPL05283P-26 4-cell 14.8V 2200mAh laptop battery

Dr. Battery MPL05283P-26 replacement

This 4-cell lithium-ion battery delivers 14.8V and 2200mAh capacity for compatible Dell Inspiron laptops. It suits owners of models such as the 14R 5421, 15R 5521 and 17R 5721 who need a new power source. Buyers whose original battery uses a different voltage or cell count cannot use this unit.

Simple swap with model verification

Installation requires removing the old pack and fitting this one in its place, a process that takes minutes on most listed chassis. The supplier advises checking the original battery part number and output voltage before purchase to avoid mismatches. No tools beyond a screwdriver are typically needed, but skipping the verification step is the main cause of fitment issues.

Fixed 14.8V 32Wh energy limit

The pack stores 32Wh at a nominal 14.8V, so runtime is bounded by that capacity and the laptop's power draw. It charges through the notebook's built-in controller and offers no higher voltage or capacity options. Users needing longer unplugged time must accept this energy ceiling or carry a spare pack.
