Bose recalls about 634,759 speaker battery packs

The U.S. Consumer Product Safety Commission says Bose is recalling about 634,759 lithium-ion battery packs for S1 Pro and S1 Pro+ portable Bluetooth speakers because the packs can overheat and ignite. The recall date is November 5, 2026. About 35,400 more were sold in Canada.

The hazard is fire and overheating. The notice says: "The recalled lithium-ion battery packs can overheat and ignite, posing a risk of injury from fire and overheating hazards." Bose has received seven reports of the packs melting, producing smoke, or catching fire, including six reports of property damage. No injuries have been reported.

The recall covers specific serial-number prefixes. The packs are for Bose S1 Pro and S1 Pro+ speaker systems and were also sold separately. The 17-digit serial number is on a label at the bottom of the pack. Recalled packs begin with 083723, 078352, 084105, 078591, 078592, 084106, or 086409.

Consumers should remove the pack and stop using it. The speakers can still be used on AC power after the pack is removed. Bose is offering a free replacement after owners register the serial number at bose.com/support/s1-battery-recall. Bose's phone line is 800-278-1083, from 9 a.m. to 9 p.m. Eastern Time on weekdays, which is 10 a.m. to 10 p.m. AST, and from 9 a.m. to 7 p.m. Eastern Time on Saturday, which is 10 a.m. to 8 p.m. AST.

The notice says not to throw the pack in the trash. It also says not to put it in curbside recycling or in used-battery boxes at stores. Consumers should ask a household hazardous waste center whether it accepts recalled lithium-ion batteries before taking one there.
