Dr. Battery MPL08257P-18 6-cell 10.8V 4400mAh laptop battery

Replacement Battery for HP Laptops

This 6-cell lithium-ion unit replaces the original power pack in compatible HP Pavilion DV6-7000, DV7-7000, Envy DV4-5200 and DV6-7200 series notebooks. It delivers 10.8V and 4400mAh for 48Wh of capacity. The black housing matches the OEM form factor so it seats securely in the existing battery bay. Builders restoring a machine from 2006 onward will find the correct fit without modification.

Fit and Electrical Requirements

The pack uses the same connector and voltage rail as the factory battery, so no adapter or BIOS update is needed. It draws charge from the standard AC adapter already supplied with the laptop. A built-in smart control chip manages the charge cycle and provides short-circuit, overheat and overload protection. The design frees the user from a tethered outlet while keeping the original chassis dimensions unchanged.

Sustained Discharge Behaviour

Under continuous load the lithium-ion chemistry maintains a stable voltage curve through most of the 4400mAh rating. The protection circuitry prevents deep discharge and thermal runaway during long sessions. Capacity remains consistent across repeated cycles rather than fading after a few heavy drains. The cell arrangement supports steady current delivery for typical productivity workloads without sudden voltage collapse.
