    Cordless tool batteries and chargers fire risk

    Do you leave your cordless batteries on the charger plugged in weeks on end? I don’t ever since a friend of mines huge shop burnt to the ground a bunch of years back.

    then today I saw another person have the same thing happen to them.

    Do you know what kind of battery/charger it was? I feel like there was an issue with the DeWalt single chargers. Good reminder though, I'm not always the best about pulling mine off the charger.

    edit: I found the one relating to DeWalts. Curious if other brands have/had similar issues. https://www.dewalt.com/support/safet...ttery-chargers

      Wow.

      I try to never leave anything plugged in, or on, or charging, when I'm not in my shop. Had a task light burst into flames on me a few months back while using it, and I'm glad i was there to disconnect it. Can't imagine what would have happened if I wasn't there.

            Fuuuudge that sucks but as least nobody got hurt. We have an attached garage with kids sleeping inside. I am glad that I decided to put all my chargers and accessories on a switched surge protector. I usually have it switched off, but now I will be more conscious of it

              I have M18 chargers with batteries in them in 4 or 5 different locations. I was under the impression that Milwaukee says it is safe to leave the batteries in 24/7. If anyone knows otherwise or has info on Milwaukee issues i would like to hear about it.

                My wife always rags on me to pull the batteries from the charger (yes its a yeller one) and dad instilled to never leave a transformer powered on when you are away and or not in close proximity of it.

                Yes dad was a BC with LAcoFD for 40+ years so very good education from him I had back in the day.

                    I doubt DeWalt has a "Danger, may burn down your house!" sticker...

                    ...or maybe they do!

                    We had part of a Slinky. But I straightened it.

                      Years ago I remember that the manufacturers recommended that you remove the batteries after fully charged. I thought that I read that M18 said that you could leave them in there and the charger would go into float mode.

                        My buddies shop burnt down, the first thing the inspector asked was how many battery chargers he had plugged in. He didn't have any in the shop at the time but it was interesting that was the first question.

                          After reading this post, I just went to the garage and took my m18 9.0 battery off the charger. This is the same battery style that cought fire 2 different times on my BILs service truck

                            This has been on my mind lately, I want to make a charging station for my tool batteries and the half dozen car batteries I like to keep topped off, thinking I'll do it in the corner off my backyard

                            I really want the pimp super organized power tool station that guys show off, but not trusting a row of slave labor chargers to not burn my house down

                              I plan on putting the "charger outlet" on a 2 hour timer.

                              Maybe I should quit planning and actually do it
