The S1 Pro uses a lithium-ion battery. Individual battery performance will vary due to battery age, storage conditions, and the number of charge cycles.

Bose does not guarantee how long a lithium-ion battery will retain its charge. However, we expect a fully charged battery in a new S1 Pro system will last 30 days with the power switch in the “Standby” () position if the system is using Firmware 7.1.51 or later.

After 30 days of non-use, the battery will enter Sleep Mode. Bose recommends that you wake up2 the battery and fully charge it at least once a year. If you leave it in Sleep Mode for longer than a year, the battery may completely discharge and become unusable.


1 Bose recommends that you update your firmware to the latest version for the best performance.

2 To wake up the battery from Sleep Mode, plug your S1 Pro into a power outlet and turn the power switch to the “On” (|) position.
