Charging a frozen battery is outright dangerous...
My boss tells me to go outside and jump start a truck. I go out with the pickup truck and a startall (well before the modern day jump packs, this thing is a engine driven high amp charging unit to charge and jump start diesel engines). I put the cables on the truck, of course after removing the drivers step. She no start! So, I leave the startall on the truck for about 10 min. I come back out, climb in the cab, and turn the key...only to be welcomed to the sound of a great explosion. I saw plastic flying out from the side of the truck...You guessed it, unbeknownst to be, the battery was frozen, and wasn't happy about being charged, and let me know! Well, after cleaning my skivvies, I was unhurt because the battery was in a location that was kinda under the truck, so no acid or plastic hit me. 2 batteries later, the truck fired up. Winter time and dead batteries = frozen!
