HP 15.4V 70W 4-Cell Replacement Battery

This new lithium-ion battery replaces HP part numbers HSTNN-1B7Z, HSTNN-1B8L, HSTNN-DB7W and HSTNN-DB8Q. It supplies 15.4 volts and 70 watt-hours of capacity across four premium cells. The unit is built for owners of compatible HP laptops who need a direct-fit replacement for a worn or failed original pack.

Lithium-Ion Chemistry and Voltage Match

Lithium-ion cells deliver stable voltage throughout the discharge cycle but require the laptop's charging circuit to manage 15.4 V exactly. The 70 Wh rating sets the practical runtime ceiling; actual battery life varies with workload, screen brightness and power-management settings. CE and RoHS markings confirm compliance with safety and environmental standards for this chemistry.

Verify Part Number and Physical Fit Before Ordering

Check the label on your existing battery to confirm it lists one of the four HP part numbers above. Ensure the laptop's battery bay accepts a 4-cell form factor, as some models use 3-cell or 6-cell packs that are physically different. Buyers who need a higher-capacity pack or a different voltage should not order this unit.
