Milwaukee Tool Expands Safety Warning on M18 High Demand 9.0 Battery Packs

milwaukee m18 9.0 battery safety notice

High demand battery packs have allowed many construction workers ditch the cords on jobsites throughout the country, by providing more power and longer runtime. As with any battery packs, it’s important to follow safety warnings, but with a higher capacity can sometimes mean greater consequences when those warnings are not followed.

After additional testing on their 9.0Ah M18 battery pack, Milwaukee Tool has recently announced an expanded safety warning to make sure that customers are aware of how to avoid potential issues.  It’s important to note that this safety warning is not a recall and it’s not unsafe to use your batteries.  To stay out of danger, your batteries should be kept out of contact with highly conductive or corrosive materials, such as seawater, industrial chemicals, and products that contain bleach.
