UPS – Pop Pop!

This happened to me last week. I was swapping out the 12v batteries in my UPS battery, and I did something fairly stupid. The batteries run in sequence, so they’re all hooked up to each other… I’m connecting them up, but the angle on some of these things are a real pain, so I get a cable to the positive terminal of one battery, then leave that cable be so I can do the negative on this other battery…

Well, anyone should have seen this coming… but the cables each click up against the frame of the ups… They arc… POP POP POP! Not good.
