Sounds as if there is a parasitic draw on the battery. You need to perform a draw test to see what amperage is being drawn from the battery while the vehicle sits. Anything more than !/4 amp will kill the battery overnight. Check for any lights that may be staying on inside the vehicle as well as outside the vehicle while it is shut off before getting involved in a draw test

My son has 2009 silverado extended cab with 22000 miles, he left his amp on and the battery went dead, so I took my 2009 silverado and tried to jump it. When I turned the key on the display lit up but once...

When a battery is totally dead a jump start will take time. The dead battery needs to come back up to at least 8 volts before it will start. Leave you jumper cables hooked up for a half hour or so and try again. What you really need is a battery charger, even once you get it running the alternator is going to have to run for a really long time to fully charge this battery. Also, you should be able to connect the amp to go off with the deck, it's a little more work but it is well worth the effort.

When i go start the car it is completely dead no lights on dashboard at all but its will start after jump leads attached first go but after half hour driving when i switch off it is completely non starting...

Sounds like your battery is bad. A car can run on just the alternator if the demands are low. You have a fairly new car. The warranty should cover the parts and the diagnostics.

For future reference, Autozone and Oreillys will scan your system for free. You can take the battery in for testing but they will have to charge it up to load test it. The reason the jump start worked is the starter will take more Amps than the alternator can generate.

I forgot to turn off the lights in my car. What can I do to start the car running? Do I need to replace the battery?

You can either jump the battery, or remove the battery from the car and bring it to your local repair shop to have it charged and tested, (a lot of auto supply stores will do this for free so call around), or you can jump start your battery and hope it holds a charge.

To jump a battery you will need a set of jumper cables and a second car, or a battery booster pack, (nice investment, they really are handy in a jam).

To jump a car with jumper cables:
******* Always where eye protection*********
1) Open the hood on the dead car and locate the battery.
2) Park the second car as close to the front of the dead car as possible, (just try to leave enough room to walk around the vehicles if you can).
3) Open the hood on the second car and locate the battery.
4) Attach the red, (positive) cable clamp to the Positive, (+) terminal of the battery on both cars.
5) Connect the black, (negative) cable clamp to the negative, (-) terminal of the battery of both vehicles.
6) With the second car running leave the vehicle to sit for about 5 minutes then attempt to start the dead vehicle.
7) If vehicle fails to start, wiggle the cable clamps to create a better connection.
8) If vehicle starts, remove the cable clamps negative first then the positive.
9) You may consider bringing the vehicle to your local auto supply to have the battery load tested once the car has run for a while, (most auto supply stores will do this for free so call around)


Using a booster pack is basically the same, except, you replace the second car with the booster pack. Follow the manufacturer’s instructions for charging the booster pack before use.

Good luck. Please rate, thanks.

I start my truck, it runs great. As soon as I shut it off it dies

You are correct. If your battery tests good, then the starter is your problem.

1985 dodge powerwagon, lights went dim driving home now wont start, just replaced battery 6 months ago. starter clicked at first then nothing.

The alternator may not be charging the battery. Jump start it, and use a volt meter at the battery, red lead to positive and black to neg. The meter should read between 13 and almost 15 volts, any lower than 13 volts, the alternator is no good. (this is done with vehicle running).

2006 Mitsubishi Eclipse won't start. Came home from work parked the car no problems at all. Few hours later went out to leave and it won't start. Just out of the blue. I was able to jump start it. No...

Battery is dead... get a volt meter, jump the car and with the car running on its own power check the voltage, anything less than 12v could point to an alternator but a new battery is a better place to start. put it to you this way if the car shuts off while driving, then its your alt, and if its fine wen drivin but wont start back up... its all battery

Won't start without a jump even with new battery

Normally a new battery would require at least 8 hours of continuous charging before it can take the full load of a vehicles lighting, starting motor etc...So please ensure that the new battery gets fully charged (ideally leave it charging for about 16 hours). I am not an expert on vehicles but I now this is how batteries (especially new batteries work). You would require a proper battery charge for this job because you cannot leave a another vehicle running with jump leads for this that long. Hope this helps.
