Replacement battery for IdeaPad 1 series

Verify the original part number before ordering

Check the label on your existing battery for any of the listed part numbers such as 31CP5/54/90, 5B11D70891 or 8SSB11D96114. Confirm your laptop model appears in the supported IdeaPad 1-14 or 1-15 families including types 82LV, 82LX, 82QC, 82R3 and 82V6. The supplier notes that voltages differ across compatible part numbers but they are interchangeable.

Fits inside the existing battery bay

The pack installs directly into the laptop's internal compartment without extra cabling or adapters. It restores mobile operation for systems that no longer hold charge and frees you from permanent mains connection. No additional hardware or software configuration is required beyond the physical swap.

Questions about this item

Does the box include only the battery or are tools and cables supplied?

The package contains the replacement battery only; no tools or cables are included.

Which part number should I match — L21C3PF0 or L21M3PF1?

Both part numbers refer to the same 42Wh 11.25V lithium-ion cell; the supplier ships whichever variant is in stock.

What runtime can I expect from the 42Wh rating in an IdeaPad 1-14ALC7?

The 42Wh capacity restores the original battery life for compatible IdeaPad 1 14- and 15-inch models.
