Here in South Dakota we like to dispose of old batteries in a big fire....

It makes the night more exciting...
From my experiences, "AA type" (AAA,AA,C,D etc.) batteries are really loud when they explode. I haven't burned a lipo yet, but I have an old lipo cell phone battery I will burn next trip to the farm.
btw I'm not a pyro,,, Just a wannabe redneck.
