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.
