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.

S1 Pro Standby

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 7.1.5[1] or later.

After 30 days of non-use, the battery will enter Sleep Mode. Bose recommends that you wake up[2] 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.
