If you own a Bose S1 Pro or S1 Pro+ portable Bluetooth speaker, take the battery pack out and check the serial number before you use it on battery power again. On Nov. 5, 2026, the U.S. Consumer Product Safety Commission (CPSC) announced that Bose is recalling about 634,759 lithium-ion battery packs in the United States, plus about 35,400 in Canada, because the packs can overheat and catch fire. Bose will mail a free replacement. Until then, you can keep using the speaker plugged into AC power with the battery removed.
Here’s how to tell whether your pack is included, what to do with it, and how to throw it away safely. Lithium-ion packs in this recall should not go in household trash or a regular recycling bin.
The recall covers the Bose S1 Pro System Battery Pack and the S1 Pro+ System Battery Pack, used with Bose S1 Pro and S1 Pro+ portable Bluetooth speaker systems. CPSC recall number: 27-065.
Affected packs were sold two ways: already installed in the speakers, and sold separately as accessories or replacement parts. A pack is included if its 17-digit serial number begins with any of these six-digit prefixes:
The serial number is printed on a label on the bottom of the battery pack. If the pack is still in the speaker, remove it first so you can read the label.
According to the CPSC, the battery packs and the speaker systems that shipped with them were sold at Bose, Best Buy and other retail stores nationwide, and online at Amazon.com, Bose.com, BestBuy.com, Walmart.com and other sites, from December 2017 through July 2026. Individual packs sold for about $100 to $160. Speaker systems sold with a pack were about $700. They were made in China and imported by Bose Corporation of Framingham, Massachusetts.
The CPSC 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 packs melting, producing smoke or catching fire, including six reports of property damage. No injuries have been reported.
That incident count is small relative to the number of packs sold, but a lithium-ion fire is not something to wait out. If your prefix matches, treat the pack as recalled even if it has worked fine so far. The same logic applies in the kitchen, where 70 broken carafes were enough to trigger the Bodum French press recall covering 5.9 million coffee makers.
You can also call Bose toll-free at 800-278-1083, 9 a.m. to 9 p.m. ET Monday through Friday and 9 a.m. to 7 p.m. ET on Saturday.
This part is easy to get wrong, and the CPSC is specific about it. Recalled lithium-ion batteries present a higher fire risk than ordinary household batteries, so they should not go in:
The agency says your municipal household hazardous waste (HHW) collection center may accept the pack. Call that office first and ask whether it takes recalled lithium-ion batteries. If it does not, ask your municipality what to do next.
Other recent home-product recalls have also involved heat and fire risks, including the DREO space heater recall and the Gourmia air fryer oven recall. If you haven’t checked those yet, it’s worth doing in the same sitting.
No. The recall is limited to certain S1 Pro and S1 Pro+ lithium-ion battery packs. After you remove the pack, the CPSC says you may continue to use the speaker plugged into AC power.
Look at the 17-digit serial number on the label on the bottom of the pack. If it starts with 083723, 078352, 084105, 078591, 078592, 084106 or 086409, it is included.
The CPSC says no injuries have been reported. There have been seven reports of melting, smoke or fire, including six reports of property damage.
No. Bose is providing a free replacement pack if you register an affected serial number on the recall site.
No. The CPSC says not to use those boxes, household trash or curbside recycling. Ask your local household hazardous waste center whether it accepts recalled lithium-ion batteries.
