Replacement battery for Lenovo Yoga Duet 7-13IML05

This 41Wh lithium-ion battery replaces the original pack in the Lenovo Yoga Duet 7-13IML05 2020 series. It delivers 7.68V and matches the black colour of the factory unit. The pack is brand new and covers part numbers L19C4PD8, L19M4PD8, 21CP4/46/113-2 and the 5B10X87839, SB10X87837, SB10X87838, 5B10X87836 codes.

Verify the exact model

Confirm that your device is the Yoga Duet 7-13IML05 and not another Duet or Yoga variant. Check the label on your existing battery for one of the listed part numbers such as L19C4PD8, L19M4PD8 or 21CP4/46/113-2. The supplier ships either the L19C4PD8 or L19M4PD8 version depending on stock, so both must be acceptable for your machine.

Direct swap for the original 41Wh pack

This unit restores the original 41Wh capacity and 7.68V specification without increasing runtime beyond the factory design. It is the correct choice when the existing cell no longer holds charge or reports a service warning. The upgrade is worthwhile only if your current battery is degraded; it does not add extra capacity over the standard specification.
