Bose is recalling more than 670,000 battery packs for its S1 Pro and S1 Pro+ Bluetooth speakers because the packs can overheat and ignite. The Bose S1 Pro battery recall covers the packs themselves, not the speakers.
The recall notice from the US Consumer Product Safety Commission (CPSC), dated 5 November 2026, counts about 634,759 packs sold in the US and about 35,400 in Canada. Together they make up the more than 670,000 total that Tom’s Guide first reported.
Bose sold the packs from December 2017 through July 2026, through Best Buy, Amazon, Walmart, and other retailers. They came both inside the speakers and separately, as accessories or replacement parts. Separate packs cost $100 to $160, and a speaker system sold with a pack cost $700. Owners who bought a spare years ago may not know their pack is on the list. Tbreak has reviewed a portable Bluetooth speaker with a replaceable battery, the Sonos Play.
Bose received seven reports of the packs melting, producing smoke or catching fire. Six involved property damage, and none involved injuries. The notice doesn’t say what causes the overheating.
Is your speaker affected?
The recall depends on the battery pack’s serial number, not the speaker’s. Bose says its speakers and battery packs have separate serial numbers, so check the one printed on the pack. The CPSC says the affected packs have serial numbers that begin with any of these:
- 083723
- 078352
- 084105
- 078591
- 078592
- 084106
- 086409
The 17-digit serial number is on a label on the bottom of the battery pack. If it begins with one of those numbers, the pack is covered.
What to do now
Stop using the pack and remove it from the speaker. The CPSC says owners should do this immediately. Once the pack is out, the speaker can keep running on AC power.
To get a free replacement, register at the Bose recall page and enter the 17-digit serial number from the pack. A pack that’s no longer in a speaker can be sent in the same way, using the serial number on the pack.
How to dispose of the pack
Don’t put the pack in the bin, in curbside recycling, or in the used-battery boxes at shops and home-improvement stores. None of those options applies to a recalled pack.
Instead, call your local household hazardous waste centre before you take the pack in. Ask whether it accepts recalled lithium-ion batteries.
