Compatible HP ProBook models

This 6-cell lithium-ion battery replaces part numbers CA06, CA06XL, E7U21UT, E7U21AA, 718677-141, 718677-421, 718678-421, 718755-001 and 718756-001. It fits HP ProBook 640 G1, 645 G1, 650 G1 and 655 G1 laptops. The pack delivers 5200mAh at 11.1V and is rated for up to 500 recharge cycles. Built-in protection covers overcurrent, overcharge, overdischarge, over-temperature and short-circuit conditions.

Upgrading from a depleted original pack

When the factory battery no longer holds a useful charge, this new unit restores full mobile runtime without changing the form factor. The 5200mAh capacity matches the OEM specification, so the swap is a direct replacement rather than an upgrade. The jump is worth it once the old cell drops below roughly half its original endurance or shows swelling, overheating or sudden shutdowns.

Suits owners of the listed ProBook G1 models

Buyers with an HP ProBook 640 G1, 645 G1, 650 G1 or 655 G1 who need a straight swap will find the correct voltage, connector and physical fit. Users of other ProBook generations, different HP series or non-HP laptops should look elsewhere because the part numbers and mechanical layout will not match.
