both lights will begin blinking green.

When the green lights are blinking, your hearing aids are charging. When the lights stop blinking and turn solid
green, your hearing aids are completely charged.

fully charged. It’s best to leave your hearing aids in the charger anytime you’re not using them, they won’t
