Replacement Battery for HP Laptops

This 7.7V lithium-ion pack delivers 56Wh from four premium cells and matches the L02031-241, L02031-2C1, L02031-541, L02475-855 and L02478-855 part numbers. It is built for owners of compatible HP notebooks who need a new power source that meets CE and RoHS requirements. The one-year replacement warranty covers material and workmanship defects.

Suitable for Direct Part-Number Matches

The unit suits buyers whose original battery carries one of the five listed HP codes and who want a like-for-like voltage and capacity restoration. It will not help users whose laptops require a different voltage, a higher watt-hour rating, or a different physical footprint, nor those who need hot-swap or multi-bay support.

Simple Internal Swap

Installation consists of powering down the notebook, removing the bottom cover, disconnecting the old pack and connecting the new one in its place. The most common issue is forgetting to detach the AC adapter before starting, which can cause a short; another is misaligning the connector, which prevents the system from recognising the battery.

Questions about this item

Does the 7.7 V 56 Wh battery need a specific HP laptop model to operate?

It fits HP part numbers L02031-241, L02031-2C1, L02031-541, L02475-855 and L02478-855; your laptop must use one of those part numbers.

Can I keep my original AC adapter when I install this 4-cell lithium-ion pack?

Yes, the replacement battery charges through the laptop's existing power circuitry, so the original adapter works unchanged.

How do I confirm the new 56 Wh pack is delivering full capacity after the first charge?

Run the HP Battery Check utility in BIOS or the HP Support Assistant in Windows; both report design capacity and current charge percentage.
