Questions about this item

Which HP laptop models does the DRPROHP271P-01 14.8V 2200mAh battery support?

It fits HP ProBook 440 G2, 445 G2, 450 G2, 455 G2, 450 G3, 455 G3 and many Envy 14, 15, 17 series models listed in the compatibility table.

Will this 14.8V 33Wh replacement battery charge correctly with the original AC adapter on a ProBook 450 G3?

Yes, the voltage and connector match the original 756743-001 and 756745-001 packs so the existing charger will charge it normally.

How can I verify the new DRPROHP271P-01 battery is working after installation?

The OS should report 14.8 V and 2200 mAh capacity, show charging progress, and the laptop should run on battery power without shutting down.
