Which is why I always charge my Stihl trimmer and chainsaw batteries in my garage. At least there is some type X (5/8” firecode) drywall between there and my house.

Do you have a smoke detector in your garage?

I have several batteries for an electric lawn mower, string trimmer and leaf blower I charge in the garage. I put a smoke detector in my garage about 6 monthos ago. Just to be safe.

Good idea for the smoke detector. I wonder if charging a roomba vacuum on its home charger is risky? Also have a small cordless Hoover vacuum that has a removable lithium battery.

I don’t have one in the garage. I do have one right above the door going into the garage though.

I do not leave them charging overnight, ever.

Smoke detectors are not recommended in garages. The possibility of a false trip is high.

Heat detectors are what is recommended in a garage.
