So I am sitting here watching football and heard a big loud boom. The Li-ion battery for my camcorder just exploded. It melted the cary strap on our camera case, put a hole in the curtains, and melted and burt a few spots on our carpet. Something tells me this isn’t normal. Now I am a little scared of Li-ion batteries. No more leaving the cell phones or laptops charging overnight.
