Big Battery vs Cheap Charger...KABOOM!!

Here's what happens when you hook a cheap charger to a big battery and walk off and leave it. The cheap little charger pumped 6 amps for 6 months into this large battery, in the Florida summer heat.

KABOOM!

I had to clean up the mess, battery acid everywhere, and remedy the situation with a marine grade starting battery and a nice, somewhat expensive intelligent charger.

Just thought you'd want to see the results of boiling a battery dry and then the cell shorts out, setting off the hydrogen gas.

HOLY CRAP! Good thing no one was around, hope the acid didn't get on anything important.

This is one of those "Do not try this at home" things.

The battery ran the 12v patient lift gate on a mobile MRI unit. It was in a large compartment underneath the floor, much like in a class A or 5th wheel, so nobody could have gotten hurt. I bet it made a colossal BANG when it went off though!!

Thanks for the info, some people do not realize how dangerous batteries can be if they don't keep an eye on them, great safety tip!
