My sister just emailed me about her having a friend jump start her late model Lexis from his F150 pickup. He got her started and then drove his truck to someplace and parked it. When he tried to start it, it wouldn't start. He had it towed to a dealership and they said his battery was fried.

In my sister's email she said that she has found out that you shouldn't jump start a car made from 2000 on.

My question is why and how do you start a car with a dead battery?
</div>

I realize that the jumping car should be running, so that gives the possiblity of too much current being drawn from the jumping car as it's got a good battery and an alternator capable of putting out well over 100A! So the jumped car's dead battery looks like a short circuit. Bad - lots of current!

So disconnecting the dead battery and putting it on a battery charger to give it a more controlled charge should be OK.

But that's not easy to do in a parking lot.

What about these jump boxes, especially the little ones like

<p class="default-style">But that is supposedly capable of 1500A!!! </p>
<p class="default-style">I did a google search on the subject and found an article talking about all the problems that you can have doing this. But the article really didn't say if these problems were to the jumping or the jumped car or both.</p>
<p class="default-style">So what is the collective knowledge about this? What am I missing?</p>
