Funny story for you hearing about batteries catching fire ect. Sunday morning I was in living room watching an F1 race on tv. Was 7:30am in the morning with curtains closed still. I was charging a battery in my room just down the short hallway. Out of the corner of my eye I seen flashing. I screamed FIRE FIRE FIRE!!! and woke everyone up in the house. I ran into my bedroom and the light bulb was flashing. My wife and two boys were then standing at the door of my room and when I seen them I said never mind just a light bulb blowing. I had massive adrenaline rush for 20 minutes after that. Kids and wife went back to bed. LOL
