Replacement battery for Lenovo IdeaPad S340 and C340

This lithium-ion battery replaces original Lenovo part numbers including L18C3PF7, L18M3PF7, L18L3PF2, L18L3PF3, L18C3PF6 and L18M3PF6. It fits IdeaPad S340-14API, S340-14IIL, S340-14IWL, S340-15IWL, C340-15IIL and related Flex 15 models. The cell ships new in black.

Capacity options of 36Wh and 52.5Wh at 11.25V.

The pack is supplied in either a 36Wh or 52.5Wh variant depending on stock; both voltages are interchangeable across the listed laptops. The lower-capacity version suits light daily use while the higher-capacity version extends runtime for longer unplugged sessions. Neither variant adds features beyond direct replacement.

Single battery unit in the package

The box contains one battery only; no tools, screws, adhesive strips or software are included. Installation relies on the laptop's existing retention mechanism. Buyers needing a full service kit or multi-pack will not find those items here.

Questions about this item

Will the 11.25V or 11.4V battery run safely in my Ideapad S340-14API that originally used a different voltage?

The supplier states that L18C3PF7, L18M3PF7, L18L3PF2, L18L3PF3, L18C3PF6 and L18M3PF6 are compatible with each other despite voltage differences and will ship whichever is available.

How can I verify the 36Wh or 52.5Wh replacement is recognised correctly after fitting it?

The laptop BIOS and Windows battery report will show the new capacity and voltage; a full charge cycle followed by a runtime check confirms it is working as intended.

Does the package include only the battery or are screws and tools supplied as well?

The package includes 1x battery only; any screws or opening tools required for installation must be sourced separately.
