Direct replacement for Lenovo IdeaPad 5 series

This 70Wh lithium-ion battery fits Lenovo IdeaPad 5-15IIL05, 5-15ARE05, 5-15ITL05 and 5-15ALC05 models including sub-variants 81YK, 81YQ, 82FG and 82LN. It replaces OEM part numbers L19C4PF1, L19L4PF1, L19M4PF1, SB10W86946, 5B10W86940, 5B10W86948 and 5B10W86950. The four-cell pack delivers 15.12V and 4630mAh capacity for restored mobile runtime.

Upgrades worn or failed original packs

When the factory battery no longer holds a useful charge or shows swelling, this unit restores the original 70Wh specification without modification. The jump is worth it when runtime has dropped below half of new performance or the system throttles due to voltage sag. It is not for users who need a higher-capacity design than the OEM 70Wh layout provides.

Limited to the original 4-cell 15.12V form factor

The pack uses the same physical envelope and connector as the Lenovo originals, so it cannot exceed the 70Wh energy ceiling or the 4630mAh charge rating. Systems that require a different voltage, cell count or connector layout will not accept this battery. Buyers who want more storage than the OEM design allows must look beyond direct replacements.
