Replacement Battery for HP Pavilion Series

This 40Wh lithium-ion unit replaces the original HS03 or HS04 pack in compatible HP Pavilion 14, 15 and 17 notebooks as well as select 240, 245, 246, 250, 255 and 256 G4 models. It is built for owners who need a direct swap without modifying the chassis or power circuit. The cell chemistry matches the factory specification so the system recognises it immediately.

Voltage-Specific Fit and Safety Protections

The pack operates at 14.6V and is also compatible with 14.4V and 14.8V original batteries, but it will not work with 11.1V or 10.85V versions that look identical. Built-in circuitry guards against short circuit, overcharge, over-discharge and over-voltage to protect both the battery and the laptop. Buyers must verify the voltage printed on their old battery before ordering.

Steady Output Under Continuous Use

The 2800mAh capacity delivers a consistent 14.6V rail during extended sessions rather than only in short bursts. Protection circuits maintain stable voltage as the cells discharge, preventing sudden shutdowns when the load remains high. This behaviour suits users who keep their notebook running on battery for long periods.
