This 42.2Wh lithium-polymer battery replaces part numbers SN03XL, ST03XL, HSTNN-DB6T, HSTNN-I42C, HSTNN-I34C, 800232-541, 800514-001, HSTNN-UB6T and LHSTNN-DB6V.

Voltage and capacity match

The single specification that decides fit is the 11.4V 42.2Wh rating combined with the listed replacement part numbers. If your original battery shows any of those part numbers the electrical characteristics will align. A different voltage or watt-hour value means the pack is not the correct replacement.

Sustained discharge behaviour

Under continuous load the lithium-polymer cells maintain a steady 11.4V output until the 42.2Wh capacity is depleted. The chemistry resists voltage sag better than older cylinder cells during long work sessions. The pack is not designed for user-serviceable cell replacement or expansion beyond the stated capacity.

Questions about this item

How long will the 42.2Wh capacity keep an EliteBook 820 G3 running on a full charge?

The 42.2Wh rating means the pack stores that much energy; actual runtime depends on the laptop’s power draw, screen brightness and workload, so it will vary from one session to another.

What does the 11.4V voltage mean for compatibility with the EliteBook 725 G3?

The battery outputs 11.4V, which matches the voltage required by the listed HP EliteBook 725 G3 and 820 G3 models, so the system will recognise and charge it correctly.

Will this pack fit inside the EliteBook 820 G4 chassis without modification?

It replaces part numbers SN03XL, ST03XL, HSTNN-DB6T and others used in the EliteBook 820 G4, so it fits the existing battery bay with no alterations needed.
