Suits owners of the listed Yoga variants needing

Buyers with non-Yoga X390 or X13 models cannot use this unit because the connector and firmware differ. Users who require a higher watt-hour rating or a different cell count should look at alternative packs. The battery is intended for the exact FRU and part numbers shown in the compatibility list.

50 Wh capacity decides runtime and fit

The 50 Wh rating determines how long the system runs between charges and confirms physical compatibility with the Yoga chassis. Verify the FRU or model number on the laptop base before ordering to ensure the correct match.
