The pack delivers 11.4V and 44Wh at 3900 mAh. Confirm the voltage printed on your old battery before ordering; a mismatch will prevent correct operation. This single electrical profile determines whether the part is suitable for your specific laptop.

Questions about this item

What run-time can I expect from the 44 Wh rating in a ProBook 640 G2?

The 44 Wh pack typically delivers several hours of mixed use in a ProBook 640 G2; actual time varies with screen brightness, workload and battery age.

Does the 11.4 V output match the original HP 801554-001 specification?

Yes, the 11.4 V rating matches the original HP 801554-001 and CI03XL batteries listed for the ProBook 640 G2, 645 G2, 650 G2 and 655 G2.

Will this battery fit the internal bay of a ProBook 655 G2 without modification?

It is built to the same form factor as the HSTNN-UB6Q and CI03XL packs, so it seats directly in the ProBook 655 G2 battery compartment.
