HP EliteBook 820 G3 G4 725 G3 replacement

The myVolts ST03XL is a new lithium-ion laptop battery built for HP EliteBook 820 G3 G4 and 725 G3 series notebooks. It replaces part numbers including ST03XL HSTNN-LB7K SN03XL 800514-001 and 800232-241. Install it when the original pack no longer holds a useful charge.

Voltage 11.55V decides compatibility

The pack delivers exactly 11.55V, matching the voltage printed on the factory battery for these EliteBook models. A different voltage will prevent the notebook from recognising or charging the pack, so verify the original label before fitting this unit.

Capacity 49Wh 4250mAh typical runtime

At 49Wh and 4250mAh the battery restores the original mobile runtime for office applications and web browsing. Heavy workloads such as sustained video encoding or discrete graphics use will drain the pack faster, and the notebook will need mains power sooner.

Questions about this item

How long will the 49 Wh capacity run my EliteBook 820 G3 in real use?

Runtime depends on workload, screen brightness and power settings; the 49 Wh rating is the energy the pack stores, not a fixed hours figure.

The battery delivers 11.55 V, matching the original ST03XL specification required by EliteBook 820 G3, G4 and 725 G3 models.

Will this pack fit the existing battery bay without modification?

It replaces part numbers ST03XL, HSTNN-LB7K, SN03XL and 800514-001, so it fits the same bay as the factory battery.
