Fits ProBook 640 645 650 655 G1

This unit suits owners of HP ProBook 640 G1, ProBook 645 G1, ProBook 650 G1 or ProBook 655 G1 who need a direct replacement for the original CA06 or CA06XL pack. Buyers whose laptop uses a different voltage, cell count or connector should look elsewhere. The supplier notes that expected run time is 1.5 to 3 hours and will vary with device type and usage pattern.

Sustained discharge characteristics

Under continuous load the six-cell pack delivers its rated 11.1V through the integrated protection circuit, which guards against over-charge, over-discharge and short-circuit conditions. Grade-A cells help maintain consistent voltage during extended sessions rather than only in short bursts. Actual endurance still depends on the notebook's power profile and workload intensity.

Questions about this item

Which HP ProBook models are supported by the CA06XL 5200mAh 11.1V 6-cell battery?

This battery fits HP ProBook 640 G1, 645 G1, 650 G1 and 655 G1, and replaces part numbers CA06, CA06XL, 718677-421, 718678-421, 718755-001, 718756-001, HSTNN-DB4Y, HSTNN-LB4X, HSTNN-LB4Y, HSTNN-LB4Z and HSTNN-LP4Z.

Will the 11.1V 6-cell design work with the original charger and BIOS on a ProBook 640 G1?

Yes. The 11.1V 6-cell lithium-ion pack matches the factory voltage and cell count, so the existing AC adapter and BIOS recognise it without any firmware update.

How can I confirm the battery is delivering the rated 5200mAh capacity after installation?

Charge it fully, then run the built-in HP Battery Check or Windows powercfg /batteryreport; the reported design capacity should read 5200mAh and the full-charge capacity should be close to that value.
