Replacement battery for Lenovo IdeaPad

The KingSener L18C4PF3 is a 15.36 V, 45 Wh lithium-ion pack built to replace Lenovo part numbers 5B10W67417, 5B10T09080, 5B10W67194, 5B10T09079, 5B10T09081, 5B10W67415, 5B10W67221 and 5B10T09077. It fits IdeaPad C340, S540 and Flex models with 14-inch chassis. The unit is brand new and carries a one-year warranty.

Voltage and connector constraints

The pack delivers 15.36 V, which is higher than the 11.36 V rating found on some look-alike part numbers; installing it in a system that expects the lower voltage can cause damage. The physical connector and screw-hole pattern match the listed Lenovo part numbers only, so compatibility must be verified against the original battery label before purchase.

Capacity and runtime headroom

Rated at 2964 mAh and 45 Wh, the battery supplies enough energy for typical office workloads on the supported 14-inch IdeaPad models. Runtime will shrink under sustained heavy loads such as video rendering or gaming, and the pack cannot be used to power larger 15-inch or 17-inch variants that demand higher watt-hour ratings.

Questions about this item

Which part number matches my Lenovo IdeaPad — L18C4PF3, L18M4PF4, L18M4PF3 or L18C4PF4?
