Replacement Battery for Lenovo Legion 2021

The KingSener L19M4PC3 is a new lithium-ion replacement battery rated at 15.36 volts and 71 watt-hours. It matches part numbers L19C4PC3, 5B10Z49581 and SB10Z49582 for direct installation in compatible Legion laptops.

Who This Suits and Who It Does Not

Owners of Lenovo Legion S7-15IMH5, S7-15ARH5, R9000X 2021 and Y9000X 2021 models can use this battery as a drop-in replacement. Buyers with R9000X 2021R or Y9000X 2020 units should look elsewhere because the connector and form factor differ.

Capacity and Runtime Headroom

The 4623 milliampere-hour cell delivers 71 watt-hours of energy, restoring factory runtime for everyday workloads and moderate gaming sessions. Heavy continuous loads will deplete the charge faster, so users needing all-day autonomy away from mains power should plan for recharging intervals.
