If the first six digits on the battery pack under your Bose S1 Pro or S1 Pro+ are 083723, 078352, 084105, 078591, 078592, 084106, or 086409, stop using that pack. Those seven prefixes mark the lithium-ion packs Bose and the U.S. Consumer Product Safety Commission pulled in recall number 27-065 on Nov. 5, 2026. The packs overheat and catch fire in documented cases, which is why the agency flagged injury risk from fire and overheating.

About 634,759 of them sold in the United States, and about 35,400 more sold in Canada, spanning years of gigs and backyard nights where the S1 Pro lived on battery power instead of a wall outlet. Bose has seven reports of packs that melted or caught fire, with smoke in some of those cases, including six reports of property damage. No injuries. That is enough for a free replacement program and a hard stop on using the old pack, even if yours has stayed cool so far.

The recall covers Bose S1 Pro System Battery Packs and Bose S1 Pro+ System Battery Packs made for those portable Bluetooth speaker systems. Some packs shipped inside the speakers. Others sold alone as accessories or replacements for about $100 to $160. Full systems with packs sold for about $700. Sales ran from December 2017 through July 2026 at Bose and Best Buy stores, through other retailers and distributors, and online at Amazon.com, Bose.com, BestBuy.com, Walmart.com, and other sites. Bose Corporation of Framingham, Massachusetts, imported the packs. They were manufactured in China. Health Canada is running the same recall north of the border.

The speaker itself is not the recalled part. The battery pack is. Your S1 Pro or S1 Pro+ carries its own serial number on the speaker body, while the pack carries a separate 17-digit serial on a label fixed to the bottom of the pack, and mixing those two numbers on the replacement form is the fastest way to stall a free swap. Bose’s replacement page wants the battery serial.

Check the pack, then pull it

You need the pack in your hand to read the right number. If it is still inside the speaker, take it out first. Bose’s steps are short:

  1. Power off the S1 system and unplug it from AC power.
  2. Flip the speaker, loosen the two screws on the bottom plate, and lift the plate off.
  3. Pull the battery pack out with the pull tabs.
  4. On the pack label, find the 17-digit serial printed below the barcode. Match the first six digits against 083723, 078352, 084105, 078591, 078592, 084106, and 086409.

If those six digits do not match any of the seven prefixes, the pack sits outside this recall and Bose’s page lists it as safe to keep using. If they do match, treat the pack as recalled right now. Stop charging it. Stop running the speaker on battery.

A spare pack that sat on a shelf still counts. Flip it over, read the same label, and run the same six-digit check. Some older S1 Pro systems sold without a battery; if you added a Bose pack later, that accessory is the one to check.

Once the recalled pack is out, keep using the speaker plugged into a wall outlet. AC power works without a battery installed, which is the bridge until the replacement arrives.

Register the serial for a free pack

Bose’s remedy is a free replacement battery pack. Register the recalled serial at bose.com/support/s1-battery-recall. Online registration is not available in every region; if the page will not take your request, call Bose toll-free at 800-278-1083. Hours are 9 a.m. to 9 p.m. ET Monday through Friday, and 9 a.m. to 7 p.m. ET on Saturday. The same recall info also sits under Product Recalls at the bottom of Bose.com.

Enter the battery pack’s 17-digit serial, not the speaker’s. Write the number down before you start disposal so you still have it if the pack leaves the house. Keep a photo of the label if that is easier than handwriting seventeen digits.

Disposal is the part people get wrong with lithium packs. Do not throw a recalled pack in household trash. Do not drop it in street-level or curbside recycling. Do not put it in the used-battery collection boxes at retail and home-improvement stores. Recalled lithium-ion packs carry a higher fire risk than ordinary spent cells, so those everyday bins are the wrong place. Call your city or county household hazardous waste office first and ask whether it accepts recalled lithium-ion batteries. If it does, take the pack there. If it does not, ask that office what local route they want you to use. Bose’s recall page and the CPSC notice both point owners to that municipal path rather than a retail drop box.

Phishing will ride this headline the way it rides every recall. Bose does not need your Bose account password from a random text that claims to hand you a free S1 battery. Type bose.com yourself, or open the CPSC recall page and follow the link from there. A message that asks you to pay shipping for the “free” pack, or to tap a shortened link to “verify” your serial, is a separate scam. The real program is free replacement after you register the pack serial.

Sellers who still have inventory of these packs should pull them. Owners who already sold a used S1 Pro with a battery should pass the serial list to the buyer when a phone number or email still works. The sale window for the recalled range closed in July 2026, but used packs and spare accessories still move through classifieds and music shops, and those packs still carry the same prefixes.

Seven incident reports against more than 630,000 U.S. packs is a small fraction on paper. Lithium packs that overheat do not always give a polite warning light before smoke shows up. The fix on offer is a free replacement and a clear serial list, so pull the pack, check the six digits against the seven prefixes, register every match for the free swap, and keep the speaker on AC until the new pack shows up.
