Replacement for HP ProBook G1 batteries

This new 6-cell lithium-ion unit replaces original HP part numbers including 718677-421, 718678-421, 718755-001 and 718756-001.

Upgrading from a depleted original pack

When the factory battery no longer holds a useful charge this replacement restores mobile operation for 1.5 to 3 hours depending on workload and device settings. The CE and RoHS certified construction targets users who need a direct drop-in spare without modifying the laptop. It is not suited for buyers who want a higher capacity than 5200mAh or a different voltage.

Check the part number before ordering

Verify that your current battery carries one of the listed HP spare numbers or HSTNN codes such as HSTNN-DB4Y, HSTNN-LB4X, HSTNN-LB4Y, HSTNN-LB4Z or HSTNN-LP4Z. Confirm the laptop model matches the supported ProBook 640, 645, 650 or 655 G1 series. The pack is new and carries a 12-month warranty with email support.

Questions about this item

Does the CA06XL 6-cell pack fit the HP ProBook 640 G1 and 650 G1 chassis without modification?

The battery replaces HP part numbers 718677-421, 718678-421, 718755-001, 718756-001 and HSTNN-DB4Y, HSTNN-LB4X, HSTNN-LB4Y, HSTNN-LB4Z, HSTNN-LP4Z, matching ProBook 640 G1, 645 G1, 650 G1 and 655 G1 models.

What is the correct sequence to seat the CA06XL battery and avoid the common latch mis-alignment?

Power off the laptop, slide the pack into the bay until the guide pins engage, then press firmly near the centre until both side latches click audibly; do not force one corner first.

When should the 5200 mAh 11.1 V unit be swapped out based on run-time loss?

Typical life is 1.5 to 3 hours per charge; replace the pack when a full charge consistently delivers less than half the original run-time under the same workload.
