That is definitely a no-go, get rid of it. My team had an issue with a battery 5 (wow it's 5 years already?) years ago, we noticed that one of our bateries was unnaturally warm. It started swelling at the sides, and we immediately decided this was a potential hazzard. We put it outside in a snow pile away from buildings, and by the end of the meeting it had melted a 3' radius in the snow. This was with the old style bateries, but regardless, you don't take chances with chemicals. Get rid of it! (recycled, of course)
