My fire was due to a 19.2V Sears cordless drill battery. I had one in the charger fully charged and put the dead battery in the charger when I found out it was completely dead. It only took 5 minutes to catch the garage on fire beyond any chance of putting it out. Apparently the dead battery had a dead short in it and the charger thought it was charging the battery, instead in got hot real fast and ignited papers and old broadcast sheets I had sitting next to the charger. I had it plugged into an old power strip straight into an outlet that went right to the breaker box. I DO NOT leave a battery being charged without me being there to watch it, especially for the first few minutes I plug it in. The insurance company (State Farm) did me good. The only things I did not get reimbursed for was my used and NOS parts since I did not have receipts for them, which was a significant loss! However they did pay for every one of my tools, but I had to buy them first then give them the receipts. I also had a collection of factory brochures from the 40's to the 90's that was lost, they paid me $5K for them, who knows how much I had in them over the years. The nightmares and agrivation still goes on today, I will never get fully over it...
