Replacement Battery for HP Envy and ProBook

This 4-cell lithium-ion pack restores mobility to compatible HP Envy 14, 15 and 17 series laptops as well as ProBook 450 G2 and G3 models. It replaces original part numbers 756743-001, 756744-001 and 756478-851 among others. The unit is brand new and ready to install.

Sustained Performance

Rated at 33 Wh and 2200 mAh, the battery delivers its stated capacity over a full discharge cycle rather than only in brief bursts. Grade A cells are specified for up to 500 charge cycles, so runtime remains consistent across months of daily use. Built-in short-circuit, overheat and overload protections keep output stable under continuous load.

Deciding Specification

The 14.8 V nominal voltage must match the laptop's original requirement exactly; a different voltage will prevent the system from recognising or charging the pack. Verify that your device appears in the supported model list before purchase.

Questions about this item

Does the 14.8 V 2200 mAh pack run hot or draw extra power during a full workday?

The 33 Wh lithium-ion cell is tested to OEM specifications and includes overheat and overload protections, so it stays within normal thermal limits under typical daily use.

What must my laptop already have for this 4-cell battery to fit and charge?

Your notebook must be one of the listed HP Envy 14, 15 or 17 series or ProBook 450 G2/G3 models that accept part numbers 756743-001, 756744-001, 756478-851, 756478-421 or 756478-422.

Will the 33 Wh replacement work reliably alongside the original charger and motherboard in an older Envy 15-K000?

Yes, the pack is built to meet the same voltage and capacity ratings as the factory unit and carries short-circuit protection, so it operates safely with the existing charging circuit.
