Replacement battery for HP Envy and ProBook
This 4-cell lithium-ion pack is built as a direct replacement for HP Envy 14, 15 and 17 series notebooks plus ProBook 450 G2 and G3 models. It restores mobile power to machines that no longer hold a charge with their original battery.
33 Wh capacity and 500-cycle rating
Rated at 33 Wh, 2200 mAh and 14.8 V, the pack delivers a full day of typical office work on a single charge. Runtime drops noticeably under sustained heavy loads such as video rendering or gaming, where the cells reach their current limit sooner.
756743-001 and 756744-001 part-number match
The battery is validated against HP part numbers 756743-001, 756744-001, 756478-851, 756478-421 and 756478-422; only systems listing one of these codes will recognise and charge the pack correctly.

Questions about this item
Will this 14.8V 2200mAh battery fit alongside the original charger I kept for my HP Envy 15?
Yes, the battery matches the OEM 14.8V specification so your existing HP charger will charge it normally.
How can I verify the 33Wh capacity is working after I install it?
Check the battery report in Windows; it should show a design capacity near 33Wh and the charge cycle count starting from zero.
