It’s a chilly morning and you’ve forgotten to plug in your block heater. Or maybe it’s a nice morning, but you left your lights on at night. Whatever the reason, the result is the same. A sick, half-hearted almost turnover when you turn the key on, or perhaps the sound of a click, or even dead silence. If the lights and radios do not turn on or fade when trying to drive, you must have a dead battery. Fortunately, there are jumper cables in your trunk and a willing friend or neighbor and most importantly know how to drive.
Start by parking the cars as much as possible without touching them. When you start the process of jumping, nobody is running. Fortunately, you just have to keep that in mind for the boosting car, as the car with the dead battery takes care of this step itself. Throughout the process, booster cables should never be allowed to touch themselves, the ground, and any damp or metallic ones. All of the interior lights, headlights, and radios should jump before you start driving. Most importantly, if the battery is frozen, cracked, leaked or otherwise damaged, do not try to encourage the car. The battery may explode.
Start by hooking booster cables in the live car, first the positive (red) cable clamp on the battery posts of the match, then the negative (black) cable. Then repeat the process to increase the car. It may be a good idea to attach a ground clamp (black, or negative flame) to anything other than a negative battery post, especially in warm weather. Everything you attach to it should be metallic, clean and unpainted. That way, when a dead car needs a burning spark to ignite, it won’t be near the battery, it may have steam burning on it.
Once the jumper cables are properly connected, try starting the car. In most cases, it will roar in favor of life. If it doesn’t, you can drop it off to charge a bit and try again or you can get a ride to the store to buy a new battery. If all fails, call a tow truck.
