how do you kill a car battery in less then 24 hours?

Answer 1

You can drain the battery, but killing it means to me you can't recharge it. A lead-acid cell is pretty darn robust, and when new even if completely drained should still recharge just fine. . .UNLESS. . . you heat it up a great deal. That could cause mechanical changes inside of it (such as plastic partitions softening and permitting contact between electrodes, or evaporating off a lot of the liquid.) Putting a large load on the battery will cause it to generate a great deal of heat and drain more quickly. That might be what happened (essentially a major short).

Why do you want to know?

Answer 2

Is this something you want to do? I don't understand the question. If you are looking to destroy a battery, shoot it. Or break the case with a hammer and let the acid out. Or short it out so it will catch fire. If you are asking "how did it go dead in a short time" it either failed (they do that) or you left lights on.

Answer 3

you need to over heat it and leave the lights and radio on..that will drain it..butt he heat will kill it...
today's alternators have a voltage cut off so it does not get over charged..if you can make the alternator continue to charge it..then you have it over heat and maybe you could even see it explode..
be careful
you could get serious burns and go blind..
good luck
