Incident: My wife and I out were out on a date night and arrived home late Saturday night. Shortly after arriving home, my wife and I hearing a loud hissing sound. We rushed to the back of the house where the sound was coming from and discovered smoke in the restroom. We assumed in was coming from upstairs because we didnt see anything on fire initially. Nothing was burning up stairs so we ran back down to the bathroom to see a huge flame. We discovered our Ryobi 4ah battery was on fire. It was not charging or plugged into any devices. Just sitting on our dry counter. It the rubber from the batter burned into our counter and charged the walls and mirrors. More damaged would have been done if our walls were [REDACTED] instead of tile.
