A common misconception is that all car batteries die. This, in fact, isn't true—the majority of "dead" car batteries just don't contain enough juice to power a car, but they can still provide enough watts to keep emergency fans and lighting running, which is great when a power outage occurs. So, instead of lugging the battery to the nearest drop-off center or just letting it collect dust in the garage, you can put that car battery to good use.
We've all been there before: We're in a hurry to get somewhere (often in bad weather), so we get in the car, turn the key in the ignition and.....WHUH! WHUH! WHUH! The darned battery is dead! After a stream of choice expletives (that is, if you're anything like me....;o)), we open the trunk and take out the jumper cables - but what if we don't know how to use them? Even if we do, we can often forget such things in crisis situations when we're pressed for time.
