Battery technology

ReSound Pulse™ uses nickel metal hydride rechargeable batteries. But it’s also compatible with non-rechargeable battery types. There are two models of instrument, designed to accommodate user preferences for either greater discretion or longer useable battery life (the 312 battery version delivers more than 20 hours of consistent high-quality performance). For extra convenience and safety, SuperTune intelligently detects whether a battery is the right type before charging begins.
