Bose Recalls S1 Pro Battery Packs Over Fire and Overheating Risk

Bose and the Consumer Product Safety Commission (CPSC) on Thursday announced a recall of lithium-ion battery packs for the Bose S1 Pro and S1 Pro+ portable speakers. The CPSC notice says the packs can overheat and ignite, creating a fire and overheating risk that could cause injury.

The recall covers about 634,759 packs in the US and about 35,400 in Canada. They were sold from December 2017 through July 2026 in Bose and Best Buy stores, through other retail outlets and distributors, and online via Amazon, Walmart and the companies' own websites. Individual battery packs sold for between $100 and $160, while speaker systems sold with the packs for $700.

Bose said it has received seven reports of packs melting, smoking or catching fire, with six involving property damage. No injuries have been reported.

The S1 Pro and S1 Pro+ are portable PA speakers with built-in mixers and Bluetooth streaming. The S1 Pro+ also supports a wireless microphone and instrument transmitter, a separate $159 purchase.

Each pack has a 17-digit serial number on a label on its bottom. Owners should check if the serial number starts with one of these codes: 083723, 078352, 084105, 078591, 078592, 084106 or 086409.

Owners should remove the battery pack from the speaker and stop using it immediately. The speaker can continue to run on AC power while waiting for a replacement. Bose asks owners to register the affected pack's serial number at bose.com/support/s1-battery-recall or support.bose.com/repair-or-replacement to receive a free replacement battery pack.

CPSC says consumers should not throw recalled packs in the trash, general recycling or used battery recycling boxes. Recalled lithium-ion batteries need different disposal because they present a greater fire risk. The CPSC also advises calling a local household hazardous waste center beforehand to see if it takes recalled lithium-ion batteries.
