Replacement Battery for HP Laptops

This 38 Wh lithium-ion pack replaces original HP part numbers OA04, OA03, 740715-001, 746641-001 and 746458-421. It fits models including the 250 G2, 250 G3, 255 G3 and 15-g020dx. The four-cell design delivers 14.8 V and 2600 mAh for direct swap installation.

Practical Limits of the Pack

Capacity is fixed at 38 Wh, so runtime scales with the notebook's power draw rather than the battery itself. The supplier rates typical use at more than 3 hours, though actual duration varies by workload, screen brightness and system settings. Recharge life is specified at more than 500 cycles before noticeable capacity loss.

Deciding Specification: 38 Wh Capacity

The 38 Wh rating is the single figure that determines whether this unit meets your mobility needs. Buyers who need longer unplugged time than the original 35 Wh or 37 Wh packs provided should look for a higher-capacity alternative if one exists for their chassis.
