Replacement battery for HP Pavilion 15 series

This lithium-ion battery replaces the original HS03 or HS04 pack in HP Pavilion 15-ac, 15-af, 15-ay, 15-ba, 15g-ad, 15q-aj and 15-bn models. It also fits the 14-ac, 14-af, 14-an, 14-am, 14g-ad, 14q-aj, 17-x and 17-y families plus HP 240, 245, 246, 250, 255 and 256 G4 notebooks. The unit ships new with a user manual. It is not for owners of other HP chassis or non-HP laptops that use a different form factor or connector.

Electrical limits of the 14.6 V lithium-ion pack

The cell chemistry delivers a nominal 14.6 V and 38 Wh from four series-connected cells. An integrated protection IC guards against overcharge, overvoltage, overcurrent, short-circuit and overtemperature events. The pack has no user-serviceable cells and cannot be charged outside the laptop's own charging circuit. Builders who need a higher voltage or a different connector pinout cannot use this unit.

38 Wh capacity and typical runtime headroom

At 2600 mAh the battery stores 38 Wh, which powers compatible 15-inch Pavilion and G4 series machines for everyday office work and media playback. Runtime falls off under sustained heavy loads such as gaming or video rendering, and the pack will not meet the needs of users who require all-day operation away from mains power without a spare.
