Before ordering, confirm that the sticker on your current battery shows L18C3PF1, L18M3PF1, 31CP6/54/90 or one of the listed substitutes such as 5B10T04975. Also verify the voltage reads 11.4V or 11.52V so the replacement matches your system requirements.

Questions about this item

Which Lenovo IdeaPad models does the L18C3PF1 L18M3PF1 battery fit directly?

The battery is listed for the IdeaPad L340-15IRH, L340-15IRH Gaming, L340-17IRH and L340-17IRH Gaming laptops.

My original battery shows 11.4 V or 11.52 V; will this replacement work with either voltage?

Yes — the supplier notes that L18C3PF1 and L18M3PF1 are compatible with each other despite the voltage difference and will ship whichever is available.

After installing the 45 Wh pack, how can I confirm it is charging correctly?

The Lenovo battery gauge should show a steady charge increase and report a design capacity close to 45 Wh once the first full cycle completes.
