Any battery capable of being recharged SCARES ME TO DEATH. (Well not quite). Doing a fair bit of electronic design in the past, I realize how fragile a circuit can be. All it takes is the wrong thing to short out/go bad and you have boining sulfuric acid and the resulting fumes. The worst story I've heard about this is from a friend who was taking a UPS maintenance class (We're talking the big 3 phase ones here). While he was taking the class, someone came in and asked if anyone in the class had a specific model of UPS installed anywhere. What had happened is that due to bad design, a solder joint would melt and "reflow" onto an ajoining trace and as a result the charger would turn on full, eventually boiling the batteries. I don't even want to think what equipment looks like after it has been through sulfuric acid vapors. - Forrest W.
