Compatible HP models

This replacement battery fits HP 240 G2, 250 G3 and several Pavilion 14 and 15 series notebooks. It matches original part numbers such as 740715-001, 746641-001 and HSTNN-LB5Y. Buyers with other HP laptop families will need a different battery.

Four-cell lithium-ion pack

The unit supplies 14.8 volts and 2600 milliampere-hours for a total of 38 watt-hours. It slots into the existing battery bay without extra cables or adapters. The pack weighs 280 grams and measures 14.33 inches by 12.83 inches by 9.06 inches.

Sustained discharge behaviour

The lithium-ion chemistry delivers steady voltage across the discharge curve rather than a sharp drop near empty. Four cells share the load to reduce per-cell stress during long work sessions. Capacity remains stable over repeated charge cycles when the battery is kept at moderate temperatures.
