14.8V 4-cell Li-ion replacement for HP ProBook

This new rechargeable lithium-ion battery delivers 14.8 volts, 2200 milliampere-hours and 33 watt-hours across four cells. It replaces HP part numbers such as 756745-001, VI04, V104 and HSTNN-LB6K. The pack fits ProBook 440 G2, 445 G2, 450 G2 and 455 G2 models as well as ENVY 14-u and 15-k series notebooks. A twelve-month warranty covers the unit.

Direct-fit design matches original mounting

The battery uses the same form factor and connector layout as the factory pack, so installation requires no adapters or cable routing changes. Users simply remove the old module and seat the replacement in the existing bay. Day-to-day handling is identical to the original equipment, with the same latch mechanism and alignment features. No additional tools or firmware steps are needed.

Restores runtime for ageing factory packs

This unit replaces depleted or failing original batteries in the listed ProBook and ENVY models, returning mobile operation to near-new levels. The upgrade is worthwhile when the current pack no longer holds sufficient charge for a typical work session or shows swelling. It does not add capacity beyond the original 33 Wh specification, so buyers needing longer unplugged time should look for higher-capacity alternatives.
