HP OA04 38Wh 4-Cell Battery

This lithium-ion battery replaces the original HP OA04 and OA03 packs in compatible Pavilion and HP notebooks. It delivers 14.8 volts and 38 watt-hours from four cells. The unit is new and includes overcurrent, overcharge, overdischarge and temperature protection.

Capacity and voltage match

The decisive specification is the 38Wh capacity at 14.8V, which must match the original battery label on the laptop. A different watt-hour or voltage rating will prevent correct charging or runtime reporting.

No bundled accessories

The package contains only the battery itself; no tools, screws, drivers or software are supplied. Buyers who need installation hardware or a diagnostic utility must source those separately.
