Seven reports, six cases of property damage and no injuries so far: that is the tally behind one of the larger battery recalls of the year. Bose is recalling 634,759 lithium-ion battery packs in the United States, the rechargeable kind that slides into the bottom of an S1 Pro or S1 Pro+ portable speaker.
The packs were sold at Best Buy and on Amazon, among other places, and some sit in speakers that have been hauled to backyard parties, school gyms and street corners for years. The fix is free, the speaker still works on wall power, and the first job is a quick look at a serial number.
What Bose Is Recalling and Why
The U.S. Consumer Product Safety Commission announced the recall on Nov. 5, 2026, under recall number 27-065. According to the CPSC notice, the packs can overheat and ignite, and Bose received seven reports of packs melting, producing smoke or catching fire. Another 35,400 were sold in Canada.
A portable speaker like this exists to play the best songs ever written at the volume of a block party, and lithium-ion trouble has been a recurring theme this year, from power banks that drew about 600 fire reports to this recall. It is a good prompt to look at everything with a battery in it.
Where the Packs Were Sold
The CPSC says the packs were sold at Bose, Best Buy and other retail stores and distributors nationwide, and online at Amazon.com, Bose.com, BestBuy.com and Walmart.com, from December 2017 through July 2026. Individual packs cost $100 to $160, and the speaker systems that included them sold for $700. Some were bought as spare or replacement parts, so a pack can be recalled even when it is not inside a speaker. A spare that rides along in a gig bag with the rest of the travel accessories counts too. The CPSC lists Bose Corporation of Framingham, Massachusetts, as the importer and says the packs were manufactured in China.
That spread of dates matters. A pack bought in 2018 and a pack bought this summer may both be affected, and a speaker that has lived in a closet since a school dance, where the playlist was probably one of the most annoying songs of all time, could still hold one. The recliner battery packs sold on Amazon are a reminder that these things hide in plain sight in ordinary gear.
How to Check the Serial Number
Bose’s recall page walks through the check. Power the speaker off and disconnect it from power, loosen the two screws on the bottom and remove the bottom plate, then pull the battery out by its tabs. The 17-digit serial number is printed on the battery label below the barcode.
A pack is recalled if the first six digits match any of seven prefixes: 083723, 078352, 084105, 078591, 078592, 084106 or 086409. Some S1 Pro systems were sold without a battery, so anyone who added a Bose battery accessory should check that one the same way. The stakes are real: one fire from a recalled power bank caused $2 million in property damage, and rechargeable gear like recalled hand warmers sits in many homes. Music fans who keep a playlist of the most influential songs queued for the next gathering have a reason to check before the next party.
What to Do With a Recalled Pack
Consumer Reports advises that “consumers should remove the battery packs immediately and request a free replacement.” Once the pack is out, the speaker can keep running while plugged into AC power, according to the CPSC and Bose. Replacements are requested by entering the pack’s serial number, not the speaker’s, on Bose’s recall page or its repair and replacement request page, or by phone at 800-278-1083.
Disposal needs more care than a typical battery. The CPSC says recalled lithium-ion packs should not go in the trash, curbside recycling or retail battery recycling boxes. Instead, a household can call its municipal household hazardous waste center in advance and ask whether it accepts them, and ask the municipality for guidance if it does not. In the meantime, the removed pack is best kept somewhere dry and away from anything flammable.
Phone Lines, Spare Packs and Other Fine Print
Bose’s phone line, 800-278-1083, is staffed from 9 a.m. to 9 p.m. Eastern time Monday through Friday and from 9 a.m. to 7 p.m. Saturday, according to the CPSC notice. Bose’s page adds that owners should write down the 17-digit serial number before starting, since the replacement request depends on it. Packs that are not installed in a speaker follow the same path: read the serial number off the label and submit it on the same site.
Online requests are not available in every region, the company notes, and anyone who cannot reach the request page can go through Bose’s international support page. The same page says an owner unsure whether a pack is recalled can contact Bose directly. Because the recall covers packs sold separately as accessories, a household with a spare in a drawer has two packs to check rather than one, and each needs its own serial number submitted.
FOX 32 Chicago, reporting on the notice, framed the instruction the same way: remove the recalled battery packs and stop using them immediately. The CPSC hotline at 800-638-2772 handles questions about the recall itself.
