Replacement for HP ProBook 640 645 650 655

This new six-cell lithium-ion battery replaces original HP part numbers including 718754-001 and CA06XL. It fits ProBook 640, 645, 650 and 655 models across the G0 and G1 generations. The black pack delivers 10.8 volts and 4400 milliampere-hours for mobile work.

Lithium-ion chemistry and voltage limits

Lithium-ion cells operate within a defined voltage window so the pack stops charging at the upper threshold and shuts down before deep discharge. The built-in smart chip manages this balance and provides short-circuit, overheat and overload protection. Users must match the original 10.8 volt rating exactly.

4400 mAh capacity decides runtime

The 48 watt-hour rating determines how long the laptop runs on a single charge. Buyers who need more storage for energy should look for a higher-capacity pack because this unit cannot be expanded. Verify the original battery part number before ordering.

Questions about this item

Should I pick the 4400 mAh or 48 Wh rating when matching my original battery?

Both figures describe the same cell pack; 4400 mAh at 10.8 V equals 48 Wh, so match either number to the label on your original HP battery.

What runtime can I expect from the 4400 mAh capacity in a ProBook 650 G1?

The 6 cell 4400 mAh pack restores the factory runtime HP specified for the ProBook 640, 645, 650 and 655 series; actual hours depend on workload, screen brightness and power settings.

Does the smart control chip use a proprietary connector or the standard HP battery interface?

The pack uses the standard HP battery interface for the ProBook 640, 645, 650 and 655 families; the built-in chip handles charging, short-circuit, overheat and overload protection through that same connector.
