Bose is recalling about 634,759 rechargeable battery packs sold in the United States for its S1 Pro and S1 Pro+ portable speaker systems because the packs can overheat and ignite, the Consumer Product Safety Commission says. About 35,400 additional packs were sold in Canada.
The firm received seven reports of battery packs melting, smoking or catching fire, including six reports of property damage. No injuries were reported, according to the November 5 recall notice.
Which packs are covered
The recall covers certain lithium-ion battery packs sold with Bose S1 Pro and S1 Pro+ speaker systems and separately as accessories or replacement parts. The affected 17-digit battery pack serial numbers begin with 083723, 078352, 084105, 078591, 078592, 084106 or 086409. The serial number appears on a label on the bottom of the battery pack.
The notice says the packs were sold from December 2017 through July 2026 at Bose, Best Buy and other stores and distributors, and online through Amazon, Bose, Best Buy, Walmart and other sites. Individual packs sold for $100 to $160; the speaker systems sold with packs for $700.
Remove, register and dispose safely
The commission says owners should remove affected packs from the speakers and stop using the packs immediately. Once the pack is removed, the speakers may still be used connected to AC power. Owners can register with Bose using the affected serial number for a free replacement; the registration address appears in the recall notice.
The notice says to dispose of affected packs in accordance with local and state regulations, and not to place recalled lithium-ion packs in trash, general recycling or retail battery recycling boxes. It advises checking in advance whether a municipal household hazardous waste collection center accepts recalled lithium-ion batteries and contacting the municipality for guidance if it does not. Bose's recall line is 800-278-1083; hours are listed in the notice.
