Buyers with matching part numbers

This battery suits owners of the listed ThinkPad models who need a direct replacement for a worn or failed original pack. It operates at 11.1V or 11.4V and matches the 24Wh capacity of the factory unit. Users whose laptops require a different voltage, a higher capacity or a different physical format should look elsewhere.

24Wh capacity at 11.1V/11.4V

The single specification that decides fitment is the 24Wh capacity delivered at 11.1V or 11.4V. Only systems designed for this exact energy rating and voltage range will recognise the pack and charge it correctly. Verify the original part number against the replacement list before ordering.
