Check the battery pack in a Bose S1 Pro or S1 Pro+ before using it again. About 634,759 packs are recalled in the US because they can overheat and ignite. The identifying serial number is on the pack, not the speaker. Stop using a matching pack immediately and follow Bose’s removal and free-replacement instructions.
Which battery packs are recalled
The recall covers packs for both speakers, the ones that came in the box and the ones sold alone as accessories or replacements. Stores and websites sold them from December 2017 to July 2026. A pack on its own cost $100 to $160. A speaker with its pack cost $700.
Bose has seven reports of packs melting, smoking or catching fire, including six reports of property damage. No injuries were reported. These reports do not establish the chance that any individual pack will fail, and a matching pack should not remain in use.
The recall names only the S1 Pro and S1 Pro+ battery packs. Bose’s headphones and earbuds, such as the QuietComfort Ultra Headphones (2nd Gen), aren’t part of it.
Checking the serial number
The number to check is printed on the battery pack, not on the speaker. Each has its own serial, and Bose’s replacement form asks for the pack’s 17-digit one.
- Turn the speaker off and unplug it.
- On the bottom, loosen the two screws and take off the bottom plate.
- Pull the pack out by its tabs.
- Find the serial number printed under the bar code on the pack’s label.
The pack is recalled if the first six digits of its serial number match any of these:
- 083723
- 078352
- 084105
- 078591
- 078592
- 084106
- 086409
A pack whose serial number does not start with one of those sequences is outside this particular recall, according to Bose. If you cannot read the number or are unsure which pack you have, contact Bose for help rather than assuming it is unaffected.
Getting the free replacement
Stop using a recalled pack right away and enter its serial number on Bose’s Start a Repair or Replacement page. Online requests aren’t open in every region. If the form isn’t available where you live, call Bose at 800-278-1083. The line is open from 9 a.m. to 9 p.m. Eastern on weekdays, with shorter hours on Saturdays.
Without a pack, the S1 Pro and S1 Pro+ still play when they’re plugged into AC power, so a show at a venue with an outlet goes on. Battery-only shows in a park or on a sidewalk wait for the new pack, and we’d file the request the same day you find a match.
Disposing of the old pack
Bose’s steps end with you disposing of the recalled pack yourself. It can’t go in household trash, curbside recycling, or the used-battery boxes at retail and home improvement stores. CPSC says recalled lithium-ion batteries carry a greater fire risk than other batteries and have to be handled differently.
Your municipal household hazardous waste center may take it. Call first and ask whether it accepts recalled lithium-ion batteries, and if it doesn’t, ask your city or town what to do with the pack.
