Hi, Frank, the Go Ultra OTC devices are digital hearing aids that amplify sounds in the range of 210 Hz to 5800 Hz. The battery life will depend on how often you use the streaming function on your devices. Without streaming the batteries can last ≥ 20 hours. Connected to Bluetooth, but not streaming it can last ≥ 8 hours. Streaming of calls, music, or media can last ≥ 2.5 - 3 hours. The hearing aids can be fully charged within 2 to 3 hours.
