49 Whr 3-Cell Replacement Battery

This 49 Whr lithium-ion battery replaces the original power pack in HP EliteBook 720 G4, 725 G4 and 820 G4 laptops. It delivers 11.55 V and 4242 mAh from three cells in a black housing. The unit is brand new and carries CE, FCC and RoHS safety certifications.

Upgrade from Worn or Failed OEM Pack

Swap this in when the factory battery no longer holds a charge or shows swelling. The 49 Whr capacity matches the original specification, so runtime returns to the level the notebook shipped with. The jump is worth it when the old cell drops below usable endurance or triggers a replacement warning.

49 Whr Capacity for Daily Mobile Work

The 4242 mAh pack comfortably powers typical office workloads, web browsing and video playback through a standard workday. It runs out under sustained heavy loads such as continuous rendering or gaming sessions that demand higher discharge rates. The three-cell design keeps weight low while restoring factory-grade endurance.

Questions about this item

Does the 3-cell 49WHR pack fit the existing bay on an HP EliteBook 820 G4?

Yes, the ST03XL is built to the same dimensions as the original 854109-850 battery and slides into the internal compartment of the EliteBook 720 G4, 725 G4 and 820 G4 without modification.

What is the correct way to seat the ST03XL connector, and what step do people often miss?

Align the 11.55V connector with the motherboard header, press firmly until it clicks, then secure the retaining screws; the common mistake is leaving the connector slightly loose, which causes intermittent charging.

When should the 4242mAh lithium-ion unit be replaced?

Replace the battery when run-time drops to roughly half of what it delivered new, or when the operating system reports a significant capacity loss after many charge cycles.
