Bose Recalls About 635,000 S1 Pro Speaker Battery Packs Over Fire Risk: How to Check Yours

The recall covers battery packs sold from December 2017 through July 2026, both on their own and bundled with the speakers, and another 35,400 or so were sold in Canada, according to the CPSC.

Quick answer: Check the 17-digit serial number on the label on the bottom of your S1 Pro or S1 Pro+ battery pack. If it starts with 083723, 078352, 084105, 078591, 078592, 084106 or 086409, the pack is recalled. Take it out of the speaker, stop using it, and register the serial number at bose.com/support/s1-battery-recall for a free replacement. You can keep using the speaker plugged into AC power in the meantime.

What the CPSC and Bose announced

According to the CPSC recall notice (No. 27-065), the recalled lithium-ion battery packs “can overheat and ignite, posing a risk of injury from fire and overheating hazards.” Bose, based in Framingham, Massachusetts, imports the packs, which were made in China.

Bose has received seven reports of battery packs melting, producing smoke or catching fire, including six reports of property damage, the CPSC said. No injuries have been reported.

Which battery packs are affected

The recall applies only to the removable battery packs used in the S1 Pro and S1 Pro+ systems, and only to packs whose serial number starts with one of these seven prefixes:

• 083723
• 078352
• 084105
• 078591
• 078592
• 084106
• 086409

The CPSC says the 17-digit serial number is printed on a label on the bottom of the battery pack, so you’ll need to take the pack out of the speaker to read it. The packs sold for between $100 and $160 on their own, and the speaker systems sold with a battery pack included for $700. They were sold at Bose, Best Buy and other stores nationwide, and online at Amazon.com, Bose.com, BestBuy.com, Walmart.com and other sites.

What owners should do now

1. Remove the battery pack from the speaker and stop using it immediately, as the CPSC instructs.
2. Check the serial number on the bottom label against the seven prefixes above.
3. Register for a free replacement on Bose’s S1 battery recall page. Bose can also be reached 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.
4. Keep using the speaker on AC power if you need it, since the CPSC says the speaker can still be used while plugged in.

How to dispose of a recalled pack

The CPSC warns owners not to throw recalled lithium-ion battery packs in the trash, in regular recycling bins or in the battery drop-off boxes found at many retail stores, because recalled batteries carry a higher fire risk. It advises calling your local household hazardous waste collection center first to check whether it accepts recalled lithium-ion batteries, and asking your city or town for guidance if it doesn’t.

What this means for you

The S1 Pro is a portable PA speaker system, and the affected packs were on sale for more than eight years, so owners who bought one years ago may not realize their battery is included. Checking takes a minute, and the replacement is free.
