Replacement Battery for IdeaPad 310-14 Series

The KingSener L15L2PB2 is a new lithium-ion replacement battery built for Lenovo IdeaPad 310-14IAP, 310-14IKB and 310-14ISK models. It matches the original physical dimensions so installation requires no modifications. The pack uses high-quality cells rated at 7.6V and 3948mAh for 30WH of energy. It replaces several Lenovo part numbers including 5B10K87712 and 5B10K90803.

For Owners Needing a Direct Swap.

This unit suits anyone whose IdeaPad 310-14 battery no longer holds charge and who wants a like-for-like replacement with the same voltage and connector layout. It is not for users of different Lenovo series or other brands, as the form factor and pin-out are specific to the 310-14 line. Buyers who need higher capacity than 30WH or a different voltage should look elsewhere.

7.6V 3948mAh 30WH Li-ion Cell Configuration

The decisive specification is the 7.6V 3948mAh 30WH lithium-ion cell configuration, which must match the original battery's electrical profile for the laptop's power management to report capacity correctly and charge safely. Confirm the original battery carries part number L15L2PB2, L15C2PB2, L15M2PB2 or one of the listed 5B10 codes before ordering.
