Bose Recalls 635,000 Speaker Battery Packs Over Fire Risk — How to Check Yours

What is being recalled

Bose is recalling about 635,000 lithium-ion battery packs used in its S1 Pro and S1 Pro+ portable speakers. The packs were sold with the speakers — and separately — from December 2017 through July 2026 at Bose stores and website, Best Buy, Amazon, Walmart, and other retailers, for about $100 to $160.

What can happen

The battery packs can overheat and ignite, posing fire and burn hazards. The U.S. Consumer Product Safety Commission (CPSC) says Bose has received 7 reports of the packs melting, smoking, or catching fire. Six of those reports involved property damage. No injuries have been reported.

How to check your battery

Look at the 17-digit serial number printed on the label on the bottom of the battery pack. Recalled packs have serial numbers starting with one of these prefixes: 083723, 078352, 084105, 078591, 078592, 084106, 086409.

What to do

If your pack is on the list, stop using it and remove it from the speaker. Your S1 Pro or S1 Pro+ still works when plugged into a wall outlet. Bose is offering a free replacement battery pack — start the process at bose.com/support/s1-battery-recall.
