Bose Recalls Batteries for S1 Pro and S1 Pro+ Speakers: Risk of Overheating and Fire

Bose has announced a recall of rechargeable battery packs used in the S1 Pro and S1 Pro+ portable PA systems. According to the manufacturer, these lithium-ion power cells can in some cases overheat and catch fire, posing fire and burn hazards. The recall applies both to batteries supplied with the speakers as standard equipment and to batteries sold separately as additional or replacement units.

Scale of the Recall

According to Bose information, approximately 670,000 devices are affected by the recall in the US and Canada. This means that significant batches of both original sets and separately purchased replacement batteries are potentially impacted. The manufacturer explicitly points out the danger associated with overheating and potential fire outbreaks, making serial number verification a top priority for owners of both models.

Which Batteries are Affected

The key reference point for the user is the battery's serial number. Batteries with serial numbers beginning with 083723, 078352, 084105, 078591, 078592, 084106, or 086409 are subject to the recall. These specific units, according to Bose's assessment, are potentially prone to overheating and catching fire. If the serial number does not match any of the listed prefixes, the battery is formally not covered by the recall scope.

What Owners Should Do

Owners of S1 Pro and S1 Pro+ speakers are advised to check the serial number of the installed or replacement battery and compare it against the list of affected series. If a match is found, they should use Bose's official recall procedure to obtain a replacement or refund in accordance with company terms. Until the check is completed and, if necessary, the battery is replaced, it is wise to limit the device's operation in conditions where a fire could lead to a major blaze.

Context and Risks

The recall affects portable professional sound systems that are often used in field and touring conditions—at events, in studios, and on stage. In such scenarios, the overheating and potential ignition of a lithium-ion battery carry an increased risk to equipment, people nearby, and facilities. Bose, like other electronics manufacturers, initiates a recall procedure in such cases to minimize consequences and replace defective components with safe ones.
