HOW TO REPLACE THE BATTERIES IN MISFIT RAY
Misfit Ray is powered by three “393” button-cell batteries. Misfit Ray should last around 4-6 months with normal use. Only replace the batteries in Misfit Ray with 393 button-cell batteries. We recommend using the same brand (or one of equivalent quality). Lower quality batteries may have shorter life.
