A battery is only an electrical STORAGE device; when functioning properly it stores electrical energy.

On the other hand, the ALTERNATOR produces the electrical energy to operate all of the electric components in the vehicle AND sends additional electrical energy to the battery for storage so that the starter can function NEXT time you want to start the engine.

If the alternator is not functioning properly the battery will eventually discharge. That doesn't mean anything is wrong with the battery, it just hasn't been given anything to store. Have a reputable auto parts retailer test your charging system for you.

At this point you should be suspicious of the alternator.

How do you know if the car needs a jump?

If you turn the key and the lights in the instrument panel dim but the engine doesn't start... or if the battery volt meter is in the red or low. This indicates that the battery is or may be dead and you need a jump. The only thing a jump can help you with is a dead battery. You may need a new battery if your engine has taken longer to start in the previous days/weeks. The battery may be fine and just need to be jumped if all you did was sayy... leave the lights on and run the battery down.


Why on my 2003 windstar with a new batteryit sets for 2 days and the battery goes dead when you try to start it the 4 way lights come on?

If I had to guess I would say you have a short in the electrical system that slowly drains the battery as it sits.

I turn the key and there is a loud clicking noise. The lights work but the engine is not turning over. Why won't my 1998 4Runner start?

Chances are that the battery does not have enough power to start the vehicle. The battery can be next to dead and the interior lights and some dash lights may come on, but a fully charged battery is necessary to start the vehicle. Have someone use a DC voltmeter to determine if you have the necessary voltage to start the vehicle. The battery should normally read 12.6 volts. If the vehicle has been sitting for a while, chances are it just slowly drained. This is called parasitic drain, and is usually a result of the clock keeping time, saving your radio station presets, etc. Normally, such a small parasitic drain does not affect the battery's ability to start the engine. However, if the battery was weak to begin with, then a minor parasitic drain could weaken the battery to the point that it cannot start the vehicle. First determine the current voltage of the battery. Determine how much voltage is currently in the battery (0v-12.6v). Try charging the battery and see if it holds the charge over the course of a couple days. If it does, then the battery probably has some life left in it. If it does not hold its charge very well, such as not even overnight, then you will definetily want to replace the battery as soon as possible. Hope this helps!
