The Right Way To Jump Start A Dead Car Battery
By Pedro Talavera



  Much has been said and written about car batteries and how to jump start a car that has a dead one. The thing is, a lot of this info is either incomplete or wrong.

  Sooner or later you will find your self in a car with a dead battery. So please read on.

  Here I will give you the right and up to dated way to jump-start a car safely. Of course this is if you are stranded away from home. When you are at home the best thing to do is use a charger, not a booster or cables. First of all I don’t recommend jumping cables to the motorist, second the best options are to use a booster or just call (an expert mobile service) or take the vehicle to an expert shop. If the battery is older than 3 years or so, it could be bad. If you must use jumper cables then here I will show the right way to do it.

















First some information about batteries.

I repair many vehicles with bad batteries. The reasons the battery went bad can be many, so after jumping a vehicle you should seek professional help. Here I will tell you what can make a battery go bad, what to do to prevent it and things to do in an emergency situation.

Why a battery goes bad:

• Bad alternator.
• Bad or loose serpentine belt or off or missing serpentine belt due to another bad component.
• Excessive  heat or cold.
• Age.
• Defective Part from factory. (Rare).
• Leaving the car sitting too long or driving the car in short trips not
   allowing the battery to recharge.
• Too much drain, like the battery is too small for the demand. Or maybe

there are add-ons like monster stereo systems etc.
• Parasitic drain. Or just leaving the lights or something on.
• Dirty connector/terminals.
• Vibration. When there’s no hold down.
• Using the wrong fluid to replenish it, like tap water instead of distilled water.
• Bad computer. The voltage regulator is there in some cars.
• Physical damage. Car accident, being dropped.

Taking care of your battery.

The best way to prevent battery failures is by doing regular maintenance on the vehicle. When regular maintenance is done the battery should be one of the main items checked. They should clean terminals, top off the fluid if possible using only distilled water, do some tests on it, and of course test the charging system etc. Even the best batteries will meet their maker sooner or later. They can "die¬hard" or die soft but they all die. The average life of most batteries is about 3 years, believe it or not. Some top of the line batteries can last a bit longer. I have noticed a decline on the life of batteries lately. So if your battery is about that age, have it checked or just change it to have peace of mind specially if you’re making a long trip.

What to do if your battery is dead.
