If you own a Bose S1 Pro or S1 Pro+ speaker, or a spare battery pack, take action today. About 670,000 lithium-ion battery packs have been recalled in the United States and Canada after seven packs melted, smoked, or caught fire. Six of those incidents caused property damage. No injuries have been reported. You do not have to stop using your speaker — but the battery pack must come out now.
The Bose S1 Pro battery recall covers about 634,759 lithium-ion rechargeable battery packs in the United States, plus about 35,400 sold in Canada. The U.S. Consumer Product Safety Commission issued Recall #27-065 on November 5, 2026. Those packs were sold from December 2017 through July 2026 at Bose stores, Best Buy, Amazon.com, Walmart.com, and other retail stores and distributors. Standalone battery packs sold for between $100 and $160. Speaker systems that included a battery pack sold for $700. Bose Corporation, of Framingham, Massachusetts, is conducting this recall voluntarily and in cooperation with the CPSC. The batteries were manufactured in China.
If your battery pack’s serial number begins with any of the seven prefixes listed below, remove the pack immediately. Stop using it unplugged and stop charging it. Once the pack is out, your S1 Pro or S1 Pro+ keeps working when plugged into AC wall power. That is standard current from a household outlet. You do not lose access to the speaker while you wait for a replacement. Register the battery pack’s serial number with Bose to receive a free replacement pack at no charge.
How to Find the Right Serial Number
The serial number you need to check is on the battery pack, not on the speaker body. Power off the system and disconnect it from all power. Turn the speaker upside down. Loosen the two screws on the bottom plate and remove it. Use the pull tabs to lift out the battery pack. On the battery pack’s label, find the 17-digit number printed below the bar code. Check whether the first six digits match any of these sequences:
083723
078352
084105
078591
078592
084106
086409
If your first six digits are not on this list, your battery pack is not part of the recall and is safe to keep using.
How to Claim Your Free Replacement and Dispose of the Old Pack
Call Bose at 800-278-1083 or visit the Bose recall registration page online. Phone support runs Monday through Friday, 9 a.m. to 9 p.m. ET, and Saturday, 9 a.m. to 7 p.m. ET. Have the 17-digit serial number from the battery pack label ready when you register. The speaker has its own separate serial number — entering that one will not get you a replacement.
Once your replacement arrives, the recalled pack cannot go in household trash or in a curbside recycling bin. It also cannot go in used-battery collection boxes at retail and home improvement stores. Recalled lithium-ion batteries carry a higher fire risk than standard batteries. Lithium-ion is a rechargeable battery chemistry that can overheat and ignite when defective. That fire risk is why the pack needs separate disposal. Contact your local municipal household hazardous waste (HHW) collection center and ask ahead of time whether they accept recalled lithium-ion batteries. If they do not, contact your municipality for guidance on where to take it.
Unlike most electronics recalls, this one does not leave you without a working device. The S1 Pro and S1 Pro+ speakers run normally on AC wall power once the battery pack is removed. You keep using the speaker through the entire process. The serial number on the speaker body tells you nothing about whether your battery pack is affected. Many owners check the speaker first. The number that counts is printed on the battery pack label, which requires removing the pack to read.
Which Bose S1 Pro battery packs are recalled?
CPSC Recall #27-065 covers Bose S1 Pro and S1 Pro+ lithium-ion battery packs, about 670,000 in total. That is about 634,759 in the U.S. and about 35,400 in Canada, sold from December 2017 through July 2026. Check the battery pack’s bottom label for a 17-digit serial number starting with 083723, 078352, 084105, 078591, 078592, 084106, or 086409.
Can I still use my Bose S1 Pro speaker during the battery recall?
Yes. Once the recalled battery pack is removed, both the S1 Pro and S1 Pro+ speakers are safe to use when plugged into AC wall power. You do not need to wait for the replacement pack to arrive before using the speaker again.
How do I dispose of a recalled Bose lithium-ion battery pack?
Do not place it in household trash, curbside recycling, or in-store used-battery collection boxes. Contact your local municipal household hazardous waste collection center to confirm they accept recalled lithium-ion batteries. If they do not, ask your municipality for guidance on where to take it.
Seven battery packs have already melted, smoked, or caught fire, causing six property-damage incidents. No injuries have been reported. Remove the battery pack now and check the 17-digit serial on the pack’s label against the seven prefixes. Register with Bose for a free replacement. Use the speaker on AC wall power in the meantime. When your replacement arrives, route the old pack through a household hazardous waste center — not the trash.
