Dr. Battery MPL08218P-16 8-cell 4400 mAh 14.4V laptop battery

Replacement battery for HP Pavilion

This 8-cell lithium-ion unit replaces the original power pack in compatible HP Pavilion dv7 and HDX 18 laptops. It delivers 14.4V and 4400 mAh for 63Wh of capacity. The black housing matches the factory finish and fits the standard battery bay. New condition ensures full runtime from the first charge.

Eight-cell construction

Eight lithium-ion cells are managed by a built-in smart control circuit that handles charging, discharge and safety functions. The chip provides short-circuit, overheat and overload protection during daily use. Connector layout matches the original design so the battery seats securely without adapters or cable routing changes.

4400 mAh capacity at 14.4V decides runtime

The 63Wh rating determines how long the laptop runs on battery power before recharging. Buyers whose original battery was a lower-capacity 6-cell pack will see longer unplugged time; those needing more than 4400 mAh must choose a higher-capacity alternative. Voltage must match 14.4V exactly or the laptop will not recognise the pack.
