I am glad your friend is OK after this accident. Batteries can explode for several reasons. For one, always remember that lead-acid batteries produce hydrogen gas when they are being charged. No smoking around them, no sparks of any kind. Turn off your charger before disconnection the leads. I had to replace my old charger due to a bad transformer; I would like to repair it if I could find a transformer for it. My old charger had an on off switch plus a timer. My new one doesn't have an on off switch so I have to unplug it to turn it on and off. Shorts in batteries can cause a large amount of current flow that can cause a battery to explode. I remember reading some BS about how a high school girl had develop a method for charging lithium cells in minutes. I thought, yeah, a high school girl had develop a method that the phD electrical engineers couldn't. Yes, you can charge any battery in minutes by pushing a large amount of current through them but you risk the battery overheating and exploding.
