Replacement battery for ThinkBook 14 Gen 6

This 45 Wh lithium-ion unit replaces part numbers L22B3pE0, L22L3pE0, L22M3pE0 and 31CP7/58/66. It delivers a nominal voltage of 11.52 V or 11.55 V depending on the specific cell batch supplied. The black casing matches the original aesthetic. Condition is new and the pack ships as a single battery.

Upgrade from a worn or failed original pack

Swap this in when the factory battery no longer holds a useful charge or shows swelling. The three listed part numbers are electrically compatible despite the slight voltage difference, so any variant restores full runtime. The jump is worth it once daily unplugged use drops below your workflow minimum.

Suits ThinkBook 14 Gen 6 owners needing a direct

Buyers who need a higher-capacity cell for longer unplugged sessions will not find that option here. Users of other ThinkBook chassis sizes or generations should verify their exact part number before ordering, as fitment is not guaranteed outside the Gen 6 14-inch line.

Questions about this item

Does the battery match the ThinkBook 14 gen 6 internal connector and screw holes?

The pack is built to the 31CP7/58/66 part number and ships as L22B3pE0, L22L3pE0 or L22M3pE0, all of which share the same form factor and connector for that chassis.

What is the common mistake when swapping this 11.52V or 11.55V pack in the ThinkBook 14 gen 6?

Forgetting to disable the internal battery in BIOS or unplug the AC adapter first; the system will not recognise the new pack until a full power cycle.

When should the 45Wh lithium-ion unit be replaced?

Replace it once runtime falls well below the original 45Wh rating or the OS reports a permanent capacity loss — typically after several hundred full charge cycles.
