I have recently discovered That my battery is under my back seat. I have been doing some reading, and I have found that this is not uncommon, but usually the posts for these batteries are usually on the sides, rather than the top. Is this a safety issue? I also would like to know what to look for as far as venting for the toxins that a battery can let off. I don't have children yet, but I do have dogs that like to go on car rides with us and They do not sit still at all. Should I be worried about them hopping around the back seat the way they do?
