Have you ever experienced that sinking feeling when you get in your car, slip the key into the ignition, turn the key, and then nothing happens. No noise, no lights, and no ignition. Your battery was dead. We are all only human. Sometimes we leave the headlights on and sometimes we leave the dome light on. Accidents happen. But, when you are faced with a dead battery, it is best to be prepared so you can be back on your merry way with only a small inconvenience.
