Bose is recalling about 634,759 S1 Pro and S1 Pro+ speaker battery packs because they can overheat and ignite, according to the Consumer Product Safety Commission notice dated November 5, 2026. About 35,400 were also sold in Canada. Bose received seven reports of melting, smoke or fire, including six involving property damage; no injuries were reported.
The 17-digit serial number appears on the bottom of the battery pack. Affected numbers start with 083723, 078352, 084105, 078591, 078592, 084106 or 086409. Packs were sold with speakers and separately from December 2017 through July 2026 at Bose, Best Buy and other stores and online retailers. Bose Corporation of Framingham, Massachusetts, is the importer.
CPSC instructs consumers to remove affected packs from speakers and stop using the packs immediately. Speakers may be used on AC power after removal. Register and provide the pack serial number at www.support.bose.com/s1-battery-recall for a free replacement. For uninstalled packs, read the serial number and submit it to the same website.
Dispose of recalled packs according to local and state regulations. Do not put them in trash, general recycling, street-level or curbside recycling bins, or retail and home-improvement store battery recycling boxes. Recalled lithium-ion batteries pose a greater fire risk and require different disposal from other batteries.
Before taking a pack to a municipal household hazardous waste collection center, contact the center and ask whether it accepts recalled lithium-ion batteries. If it does not, contact the municipality for guidance. CPSC lists the official Bose recall website for replacement registration and further information.
