Compatible Replacement Battery

The GreenTechLLC L20M3PC2 is a 3-cell lithium-ion battery built for Lenovo IdeaPad 3-15ACH6 and IdeaPad Gaming 3-15ACH6 models including the 82K2 and 82MJ variants.

Voltage and Cell Limits

The pack operates at 11.52V using three lithium-ion cells, a fixed voltage that matches the original design. The cell count and chemistry set the electrical boundaries; the battery cannot be reconfigured for higher voltages or different cell arrangements. It is certified to CE, FCC and RoHS standards for safe operation within those parameters.

Capacity and Runtime

Rated at 3910mAh and 45Wh, the battery supplies a defined energy reserve for typical office and light gaming sessions. Runtime scales with workload; heavy discrete graphics use or sustained high brightness will deplete the pack faster than light browsing. It is not suited for users who need all-day operation without recharging.
