does a thermacell use batteries
No Batteries. Ok I told a little white lie just now, the ThermaCell does not run on batteries. It actually runs on a tiny butane cartridge that plugs into the bottom of the iron. Now I know this, itâs not anything I would ever use in the car, and you shouldnât either. Thatâs a hazard, and not anything you (or I) want to mess with.
