Dr. Battery MPL05278P-22 4-cell lithium-ion

The Dr. Battery MPL05278P-22 is a 4-cell lithium-ion replacement battery rated at 14.8V and 2200mAh. It is designed for a wide range of Dell Inspiron 14, 15 and 17 series laptops including the 14-3000, 15-3000 and 17-5000 families. This new unit targets owners of compatible Dell notebooks who need a direct replacement for an ageing or failed original pack. Buyers with laptops outside the listed Inspiron model numbers cannot use this battery.

Black 4-cell pack with smart control chip

The black battery housing contains four lithium-ion cells and an integrated smart control chip that manages charging and discharge cycles. Built-in protections guard against short circuit, overheat and overload conditions during daily use. The physical connector and mounting points match the original Dell design for the supported Inspiron models, allowing straightforward installation without modification. Systems requiring a different cell count, voltage or form factor will not accept this pack.

33Wh capacity decides runtime

The battery stores 33Wh of energy, a figure that directly determines how long the laptop can run unplugged. This capacity suits users replacing a standard 4-cell 2200mAh pack in the compatible Dell Inspiron models listed. Buyers who need higher capacity for longer runtime or a different voltage for another laptop series must select a different battery.
