It absolutely is......... But what part? check all that you can, does anything light up when the jumper cables are hooked up? lights? glove box light? dome light? sun visor mirror lights? The alternator can short out and drain the battery. Disconnect it (the large cable) and put a test light in line, it should NOT light up. If you cant find anything obvious, a shop may have to check for a battery draw.

There is an electrical short draining the battery. . You can check each fuse one at a time to find the circuit & trace the wire to find the short. Make sure all electrical things are working, if u find something not working you can strt looking through that circuit for the short

Car keeps needing to be jumped because of dead battery, I have replaced battery and it still needs to be jumped

Check for a drain by putting an inductive ammeter probe around the positive or negative wire on the battery.

If there is more than .2 Amps of draw when the car is not on, then you have too much of a drain caused by something in the car's electrical system.

Take the car to an auto electric shop to try to find the short or source of the drain.

I have burned through three batteries in one year. I think i have an electrical drain on the battery. once its jumped, it runs perfect. doesnt seem to hold a charge. the alternator and starter work fine....

You need to have a technician familiar with car electrical systems check for parasitic drain. This can be as simple as a vanity mirror light or glovebox light remaining on all the time.

2000 Dodge Ram cargo van trouble starting and once started will not keep running tried jumping battery and no change what should we try next?

Sounds like the alternator is bad (not charging). If your battery is good/charged it should run until the battery is drained. If the battery is bad/not charged the car will die as soon as the cables are taken off as there is not enough juice to run the ignition system. If the alternator is good (but battery bad) the car would still run as the alternator makes power to run the car but becasue the battery is dead/drained there is no power to start the car (hense needing the jump). Have the alternator/charging system tested

Car battery problem

The alternator test will likely indicate a charging problem from the alternator that is not keeping the battery charged up.
Regardless of the alternator test, it would be best to do an electrical draw test to determine whether there is an excess drain on the battery. This can be done with an ammeter between the positive terminal and the positive battery post. This test is done with key off, all accessories off, no lights on, etc. There will be a small draw on the battery in all newer vehicles, but it should be in the order of up to 50 milliamps. If you are getting more than 200 milliamps of current draw then there is a problem with an electrical system that will drain the battery over a period of days or weeks. Once you know this is true, the electrical systems can be methodically tested.

Power drains while driving is it my battery ?

If you jumped the car already and it seemed fine while the cables were connected to the other car, then the electrical systems began to fail after the cables were disconnected, your most likely culprit is the alternator.

Once the car is started, all the electrical systems should be running off your alternator, not the battery itself. When the alternator goes out the electrical systems on most modern cars will continue to feed off the battery instead of the alternator. When this occurs you will see your battery light illuminate on the dashboard display for most vehicles.

Your best bet when you see the electrical systems failing like this is to get the car to a safe location quickly as once the battery voltage gets too low, the electrical systems (including your computer which controls timing and everything in your engine) will fail and the car will stop running.

If this is the case the car does not necessarily need to be towed. If you intend to move it on your own, you should 1 turn off all headlights, radios and everything else that is a drain on the electrical system (heat/ac, etc), jump the car using another with a good alternator and battery. Leave the cars connected and running for 15-20 minutes or so and have the person follow you DURING THE DAY only. Do not attempt this at night as your headlights will be a major drain on the battery and in the event they go out you could cause an accident.

If you are only running vital systems off the now fully charged battery, you should be able to get 5-10 miles before the battery clunks out on you again. This process can be repeated until you reach your repair center, but the safest and best option is to simply have the vehicle towed to it's destination. This option is only for those who can not afford it and are willing to take the risk. If you car dies in an area where it cannot be jumped easily, you will most likely need to have it towed anyway, but if your destination is within 10 miles or so, this option can save you a lot on the towing fees.
