HP V104 replacement battery

This new 48 Wh battery replaces part numbers such as 756743-001, 756745-001, HSTNN-DB6I and HSTNN-PB6I in compatible HP notebooks. It is built for owners of Envy 14-V, 15-K and ProBook 440 G2, 445 G2, 450 G2, 455 G2 models who need a direct-fit power source. The unit delivers more than three hours of continuous runtime on a single charge. It has passed CE, FCC and RoHS testing for safety and quality assurance.

Installing the V104 cell

The battery slots into the existing bay without adapters or cable changes, freeing the AC adapter for desk use while the pack powers the laptop. It supports the original charging circuit and firmware, so no BIOS update or driver installation is required. Compatibility spans the listed part numbers including 756478-421, 756478-422, 756478-851, 756479-421, 756744-001 and 756748-851. Buyers whose HP model uses a different spare code or form factor cannot use this unit.

Sustained discharge and cycle life

Rated for over 500 recharge cycles, the pack maintains capacity through daily charge and discharge routines rather than only brief top-ups. The 48 Wh rating supports steady workloads such as document editing or video playback across a full work session. Cell balancing and protection circuits operate continuously during extended use to prevent over-charge and deep-discharge damage. Users who need higher capacity for all-day unplugged operation should consider a larger-capacity alternative if available for their chassis.
