If it shorted out, it will pull enough current to overload (and possibly damage) the alternator and cause enough drag to kill the engine. It won't jump start either. The engine of the other car will slow down, and the jumper cables will heat up. Even running, the load of the shorted battery will cause a low voltage condition causing all sorts of issues for the computer. I have seen two different cars just recently where batteries less than 90 days old have shorted out. Somebody (there are only a couple of companies that make batteries, they just change the labels for the different brands) is making junk batteries. I use Delco and have had no problems, Interstate seems to be okay. The bad ones were both from AutoZone.
