Replacement battery for Lenovo Ideapad L340

This KingSener L18C3PF1 lithium-ion battery delivers 11.52 volts and 45 watt-hours of capacity at 3950 milliampere-hours. It is a brand-new unit built to replace the original power source in compatible Lenovo gaming notebooks. The black housing matches the OEM appearance and fits the designated battery bay without modification.

Direct part-number match for easy installation

The pack replaces Lenovo part numbers L18M3PF1, 5B10T04975, 5B10W67350, 5B10T04976, 5B10W67336 and SB10W67243. No additional cables, adapters or software are bundled; the battery simply slots into the existing connector. This one-to-one compatibility removes guesswork during the swap and restores mobile operation immediately.

Suits owners of L340-15IRH and L340-17IRH models

Buyers with those specific Ideapad gaming laptops gain a fresh 45 Wh power pack. Users of other Lenovo series, different screen sizes or non-gaming variants should verify their part number before ordering, as the connector and cell layout differ across the range.

Questions about this item

How many charge cycles before the 3950mAh capacity degrades noticeably?

The lithium-ion cells are rated for typical cycle life; expect gradual capacity loss after several hundred full cycles.

What thermal limit appears first when the 11.52V pack runs continuously in a Lenovo Ideapad L340-15IRH?

The battery management circuit will throttle output if cell temperature exceeds its safety threshold during sustained loads.

Does the L18C3PF1 generate audible noise or excess heat while powering a L340-17IRH all day?

No moving parts mean silent operation; warmth is normal under load but stays within the pack's designed thermal envelope.
