Replacement battery for Lenovo IdeaPad 510

This lithium-ion battery delivers 39 Wh at 7.72 V and 5055 mAh for compatible IdeaPad 510-15ISK, 510-15IKB, 310-15ISK, 310-15IKB, 310-15ABR and 310-15IAP models. It replaces part numbers L15M2PB5, L15L2PB5, L15M2PB3, L15L2PB4, L15S2TB0, L15C2PB3, L15C2PB5, L15C2PB7, 5B10K90787 and 5B10L13960. The pack is new and built with quality cells and a smart protection circuit. It restores mobile runtime for owners of these 15-inch IdeaPad laptops.

Fits directly into the original battery bay

The unit matches the mechanical and electrical layout of the factory pack, so installation only requires removing the bottom case screws and swapping the connector. No additional cables, brackets or BIOS updates are needed. It frees the notebook from permanent mains tethering and restores true portable operation. Buyers whose laptops use a different battery form factor or voltage cannot use this pack.

Maintains steady voltage through a full discharge

The integrated smart chip manages cell balance and protects against over-charge, over-discharge and short circuits, keeping output stable during extended workloads. Low self-discharge chemistry preserves stored energy when the laptop sits idle for weeks. UL, CE, FCC and RoHS certifications confirm compliance with recognised safety standards. The pack is not designed for high-drain gaming sessions that exceed its rated capacity.

Questions about this item

How long will the 39Wh 5055mAh capacity last before the battery needs recharging during continuous use?

The 39Wh 5055mAh rating indicates total energy storage; actual run-time depends on the laptop model and workload, so no single figure applies to every IdeaPad 510 or 310 series listed.

Does the Li-ion pack run hot or make noise when the laptop is on all day?

The battery itself has no moving parts and generates minimal heat; any warmth or fan noise comes from the laptop chassis, not from this 7.72V Li-ion cell.

Which part numbers must my Lenovo already use for this replacement to fit?

It replaces Lenovo part numbers L15L2PB4, L15L2PB5, L15C2PB5, L15M2PB5, L15M2PB3, L15C2PB3, L15C2PB7, L15S2TB0, 5B10K90787 and 5B10L13960.
