Replacement for HP ProBook series

This 6-cell lithium-ion battery replaces original HP part numbers 718754-001 through 718757-001 and the CA06, CA06XL, CA09, HSTNN-DB4Y and HSTNN-LB4X packs. It fits ProBook 640, 645, 650 and 655 models including G0 and G1 revisions. The pack delivers 10.8V and 4400mAh capacity.

Upgrade from worn original packs

When the factory battery no longer holds a useful charge or shows swelling, this new unit restores the original 48Wh runtime. The jump is worth it if your laptop shuts down early, runs only on mains power or the system reports a permanent battery fault. A built-in smart chip manages charging and protects against short circuit, overheat and overload.

Check model and voltage before ordering

Confirm the exact ProBook model number on the bottom case or in BIOS matches the supported 640, 645, 650 or 655 series. Verify the original battery label shows 10.8V output and one of the listed part numbers. This pack is not for buyers who need a higher-capacity 9-cell design or a different voltage.
