Compatible Galaxy Watch 6 Classic 43mm

This replacement battery kit is built for the Galaxy Watch 6 Classic 43mm models SM-R950 and SM-R955. It supplies a fresh Li-Po cell so owners can restore original runtime without sending the watch to a service centre. The package includes a full toolkit and a step-by-step repair guide for a self-service swap.

UL2054 tested Li-Po cell limits

The cell is manufactured and tested under UL2054 standards, which define safety requirements for household and commercial batteries. That certification covers electrical, thermal and mechanical abuse but does not extend the watch’s own power-management firmware or guarantee a specific runtime figure. The battery still relies on the watch’s original charging circuitry and calibration routine.

Verify exact model before ordering

Confirm the case back reads SM-R950 or SM-R955 for the 43mm Classic variant; other sizes or non-Classic models use different cells and flex cables. The kit’s tools match the fasteners and adhesive layout of those two model numbers only. Plan for at least three full charge and discharge cycles after installation so the battery management system can recalibrate correctly.
