Charging and checking the battery level

Each time you power on your speaker, the battery indicator displays the battery charge level for several seconds, and if enabled, a voice prompt announces the battery charge level.

To check battery level while using your speaker, press and hold the Power button to hear a voice prompt indicating battery level. The battery indicators will also light up for several seconds.

Battery storage guidelines

Do not store your speaker for more than 90 days when fully charged or with a remaining charge of less than 10 percent. If the speaker needs to be stored unused for an extended period of time, it's best for the battery level to be between 50 – 80 percent.

Battery protection mode

When your speaker battery is depleted (0%), and remains unplugged for more than 90 days, it enters safety protection mode and is permanently disabled. If your speaker enters safety protection mode, contact Bose customer service.
