Call for Stopping Use of Third-Party Battery Packs for Cordless Vacuum Cleaners Imported by Sumitomo Shoten and Rowa Japan

*Very dangerous: they may catch fire even while being stored and not charging*

October 29, 2021

Many fires appear to have been caused by third-party battery packs that can be attached to Dyson cordless vacuum cleaners. These battery packs were imported by Sumitomo Shoten and Rowa Japan. The battery packs have already been recalled, but they are very dangerous products and may catch fire even while being stored and not charging. If you have this battery pack, stop using it immediately and store it in a metal container, such as a pot or empty can, so fire from it will not spread to anything burnable.
 The product may catch fire even while being stored, so please do not throw it away, and store it in a safe manner. Collection, disposal methods, and other details will be verified with the concerned parties and announced at a later date.

1. Product verification method

Please check the labeling on your battery pack to determine if it is the model found to have caused fires. If it is, the name of the importer (Orange Line DC60 or ROWA JAPAN DC62) should be written as shown below.

2. If you have this product

Investigations by the National Institute of Technology and Evaluation (NITE) confirmed today (October 29) that the battery packs' PCBs heat up and can catch fire even while being stored and not charging, which makes them extremely dangerous products.
For this reason, stop using it immediately and do not charge it. In addition, until the disposal method, etc. is determined, please store it in a metal container (such as a pot or empty can) and keep it away from anything burnable, in order to prevent extensive damage should it catch fire.

Reference:Situations when accidents occurred, developments leading to the recall, and an outline of the issue
