Compatible HP replacement battery

This 14.8 V lithium-ion pack replaces original HP batteries marked LA04, 776622-001, 728460-001, 752237-001 and related part numbers. It fits selected HP 248, 248 G1, 340, 340 G1, 350 and 350 G1 series notebooks as well as Pavilion 14 and 15 TouchSmart models. The four-cell design delivers 38 Wh of capacity for everyday mobile use.

Not for every HP 14 or 15 model

Buyers whose original battery carries a different part number such as LA03 or other variants listed under 776622-001 should look elsewhere because this unit only matches the LA04 revision. Users needing a higher capacity than 38 Wh or a different voltage will also need another solution.

Key spec is the 14.8 V 38 Wh rating

The battery supplies 14.8 volts and 38 watt-hours through a four-cell lithium-ion construction. Confirm that your original battery shows the same voltage and the LA04 marking before ordering.
