80Wh replacement battery for Legion Slim 5

This lithium-ion pack delivers 80Wh at 15.44V and fits Lenovo Legion Slim 5 and LOQ 16-inch 2023-series models including 16APH8, 16IRH8, R7000P and Y7000P variants. It replaces part numbers L22B4PC2, L22C4PC2, L22D4PC2, L22L4PC2, L22M4PC2 and the SB11K and 5B11K series codes.

Cool-running lithium-ion chemistry

The cell chemistry operates within normal laptop thermal limits and requires no fan or heatsink. Power draw follows the host system's charge controller, so the battery adds no audible noise and does not increase the chassis temperature beyond the original design envelope.

Drop-in fit for listed 16-inch 2023 chassis

The pack matches the original form factor and connector layout, so it seats in the existing battery bay without adapters or cable routing changes. It frees the owner from hunting for a specific L22 sub-variant because the listed part numbers are cross-compatible and the supplier ships whichever code is in stock.

Questions about this item

How do I install this 15.44V 80Wh battery in my Legion Slim 5 and which step do people skip?

Power off the laptop, unplug the AC adapter, remove the bottom case screws, disconnect the old battery connector from the motherboard before lifting it out, fit the new pack and reconnect the cable; the step most often missed is disconnecting the battery cable before removing the original pack

What maintenance will this Li-ion 80Wh pack need later?

No scheduled maintenance is required; keep the charge between 20 % and 80 % when possible, avoid leaving the laptop at full charge or fully drained for weeks, and store at room temperature if unused for long periods

What limit appears first during sustained heavy use on this 15.44V 80Wh battery?

The pack will hit its thermal and voltage sag limits first; under continuous high load the cell temperature rises and the voltage drops, triggering the laptop to throttle performance to protect the 80Wh cells
