Jump-Starting Your Battery Using Another Car

Whether it's because you left the lights on, the keys in the ignition, or your battery is old, most car owners will be faced with a dead battery sooner or later. Fortunately, if there's another functional car nearby, or if you have a manual transmission, you can jump start the car and be on the move again soon.
                 Check the headlights. Are they dim or bright? (Note that in some cars you will need to turn the ignition on to test the headlights). If they are dim, it's likely your battery is the culprit. If your headlights are bright, you do not have a dead battery and a jump start will not help.
