Bose S1 Pro and S1 Pro+ Battery Packs Recalled for Fire Risk: CPSC

Bose is recalling lithium-ion battery packs for its S1 Pro and S1 Pro+ portable Bluetooth speaker systems because the packs can overheat and catch fire, the CPSC says in a notice dated November 5, 2026. If you own either speaker, remove the battery pack, stop using it and check its serial number. This Bose S1 Pro battery pack recall also covers packs sold separately.

Products Affected by This Recall

The recall covers Bose S1 Pro System Battery Packs and S1 Pro+ System Battery Packs, the rechargeable lithium-ion packs made for Bose S1 Pro and S1 Pro+ Portable Bluetooth Speaker Systems. Some shipped inside the speaker systems. Others were sold alone as accessories or replacement parts.

Your serial number decides whether the pack is included.

Serial number prefixes: the notice lists these starting digits: 083723, 078352, 084105, 078591, 078592, 084106 and 086409.
Where to look: a label on the bottom of the pack carries the 17-digit serial number.
Packs outside a speaker: you can read the number straight off the label and give it to Bose.

The Reason Behind the Recall

According to the CPSC, the packs can overheat and ignite, which creates a risk of injury from fire. Bose has received seven reports of packs melting, producing smoke or catching fire. Six of those involved property damage.

Where Were These Products Sold?

Bose, Best Buy and other retailers and distributors sold the packs nationwide. Online sales went through Amazon.com, Bose.com, BestBuy.com, Walmart.com and other websites. Sales ran from December 2017 through July 2026. Individual battery packs cost between $100 and $160, while the speaker systems, sold with the packs, cost $700.

About 634,759 units were sold in the United States and about 35,400 in Canada. The recall was announced in conjunction with Canada. Bose Corporation, of Framingham, Massachusetts, is the importer, and the packs were made in China.

Steps Consumers Should Take

You do not have to give up the speaker itself. With the pack out, the S1 Pro or S1 Pro+ still works while plugged into AC power.

Take the battery pack out of your speaker and stop using it right away.
Find the 17-digit serial number on the label at the bottom of the pack.
Go to www.support.bose.com/s1-battery-recall, register and enter the serial number to receive a free replacement battery pack.
Prefer the phone? Call Bose toll-free 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. You can also visit www.bose.com and click ‘Product Recalls’ at the bottom of the page.
Dispose of the recalled pack under local and state rules. Keep it out of household trash, curbside recycling and the used-battery boxes at retail and home improvement stores.
Before you drive to a household hazardous waste center, call ahead and ask whether it accepts recalled lithium-ion batteries. If it does not, ask your municipality for guidance.

Quick Answers

Can I keep using my speaker?

Yes, according to the notice. Once the battery pack is removed, you may keep using the speaker while it is connected to AC power.

Why can’t I drop the pack in a store recycling box?

The CPSC says recalled lithium-ion batteries carry a greater fire risk than other batteries and must be handled differently.

What does the replacement cost?

Nothing. Bose will send a free replacement battery pack after you register the serial number.

What the Agency Said

The CPSC lists this as a Fast Track recall under number 27-065, with replacement as the remedy. The agency also notes that federal law bars the sale of products covered by a voluntary recall run in consultation with the commission.
