KingSener L22L3PA4 laptop battery 56.6Wh 4914mAh 11.52V

Replacement battery for IdeaPad Slim 5

The KingSener L22L3PA4 is a 56.6Wh lithium-polymer battery built to replace the original pack in select Lenovo IdeaPad Slim 5 models. It delivers 4914mAh at 11.52V and matches the form factor for 14-inch and 16-inch variants including 14ABR8, 14IRL8, 16ABR8, 16IAH8 and 16IRL8 chassis. The unit ships new with a black finish and covers part numbers such as L22B3PA4, L22M3PA4 and L22C3PA4.

Thermals and power draw in daily use

Li-polymer chemistry keeps self-discharge low so the pack holds charge well between sessions. Normal office workloads draw modest current, letting the battery run cool without active cooling. The 11.52V nominal voltage aligns with the laptop’s power management, so the system reports capacity accurately and throttling stays minimal during typical browsing or document work.

Behaviour under sustained load

Continuous heavy use such as video export or compile jobs will drain the 56.6Wh reserve faster and raise cell temperature, but the chemistry tolerates the heat within spec. Voltage sag stays controlled through the discharge curve, so the laptop maintains performance longer before hitting the low-power state. Users needing all-day runtime away from a socket should plan for a midday recharge or carry a spare pack.
