What is also an eye opener, is the number of calls that the Fire Department responds to regarding garage fires caused by tool batteries being charged in tool boxes or on walls line we all do….
I now only charge when I am at home and present. This personal rule applies to all of our rechargeable stuff. Even when we need to throw on the Simply Safe camera battery. We can only do what we can to reduce the risk without living in a protective bubble of plastic.
(Which will melt in a fire, so we’re screwed [emoji6])
