Replacement Battery for HP 240 G2

This 41 Wh lithium-ion pack replaces the original OA03 and OA04 modules used in the HP 240 G2, Compaq Presario 15-h000 and 15-S000 series. It delivers 14.8 V from four cells rated at 2200 mAh. The unit is brand new and matches the black finish of the factory battery.

Fits Without Extra Hardware

The battery slides into the existing compartment and connects to the same motherboard header, so no adapter cables or firmware updates are required. It restores mobile operation for systems currently running only on AC power. The four-cell layout keeps the profile identical to the original part.

Suits Owners of Listed HP Notebooks

Buyers with an HP 240 G2, CQ14, CQ15 or compatible Presario 15 model can use this as a direct swap. Users whose laptops require a different voltage, cell count or part number should look elsewhere.

Questions about this item

How long will the 41 Wh capacity last under continuous load?

The 41 Wh rating means the pack can deliver 41 watts for one hour; actual runtime depends on the laptop's power draw and the 2200 mAh cell capacity.

Does the 14.8 V pack run hot or draw extra power during all-day use?

A 14.8 V lithium-ion pack generates normal warmth under load; it does not add active cooling or change the notebook's power profile.

Which HP part numbers must my laptop already use for this battery to fit?

It replaces HP part numbers 740715-001, 746641-001, 746458-421 and 751906-541 and fits models such as HP 240 G2, CQ14, CQ15 and Compaq Presario 15-h000 or 15-S000.
