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.

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.
