Compatible replacement battery

This 11.55 V lithium-polymer pack replaces the SS03XL unit found in several HP EliteBook and ZBook 14U models. It fits G5 and G6 series notebooks including the 730, 735, 740, 745, 830, 840 and 846 families. Buyers should verify the original battery matches the product photo before ordering.

Build and connectors

The battery uses the same form factor and connector layout as the factory HSTNN-LB8G, HSTNN-DB8J and HSTNN-IB8C units. Installation requires opening the chassis and disconnecting the old pack; cable routing and physical dimensions follow the original design. Units with different wire lengths or case sizes will not seat correctly even when the part number matches.

Thermals and power

Rated at 50 Wh and 4330 mAh, the cell delivers the same voltage and capacity as the original equipment. Normal operation stays within the laptop’s thermal envelope when charged with the supplied adapter. Avoid discharging to zero percent to preserve long-term cycle life.
