Replacement Battery for HP ProBook Series

This new 6-cell lithium-ion unit replaces original HP part numbers 718754-001 through 718757-001 and the CA06 series. It fits ProBook 640, 645, 650 and 655 models across G0 and G1 generations. The black casing matches the OEM form factor for direct installation.

4400 mAh Capacity at 10.8 V

The single specification that determines fit is the 48 Wh energy rating delivered by six cells at 10.8 volts. Buyers must confirm their original battery shows the same voltage and one of the listed part numbers before ordering. Systems requiring a different cell count or voltage will not accept this pack.

Smart Chip Protection and Efficient Discharge

An integrated control chip manages charging current, prevents short circuits and guards against overheating or overload during normal use. The circuitry lowers idle power draw to extend runtime between charges. No active cooling is required as the pack relies on the laptop's internal thermal design.
