Direct replacement for HP and Compaq laptops

This 6-cell lithium-ion battery is designed to replace original units in a wide range of HP Pavilion, G-series, HDX and Compaq Presario models. It operates at 10.8 volts and delivers 4400 milliampere-hours of capacity for mobile computing.

Fits existing bays without extra hardware

The pack slots into the standard battery compartment of compatible notebooks, requiring no adapters, cables or firmware updates. It frees the user from a wall outlet by restoring the original runtime envelope of the supported systems.

Steady output through smart-cell management

An integrated control chip regulates charge and discharge cycles, providing short-circuit, overheat and overload safeguards during extended sessions. The cell chemistry maintains consistent voltage under sustained load rather than peaking only in short bursts.
