1. Remove the battery wires and thoroughly clean all connections with a wire brush, that may take care of the problem.
2. If it doesn't, check to see if the charging system is good. You will need a digital voltmeter for this. To check the charging system, place one lead on the positive terminal, and another on the negative, with the engine running and lights off. You should get at least 14 volts. (You may need to have a helper accelerate slightly to get the 14 volts.) If not, the charging system is bad. Take the alternator off, and have the auto parts store test it before buying a new one.

Will not start unles you jump start

Check the starter/solenoid. If you have a weak starter or solenoid, it could need the extra voltage put into your electrical system when doing a jump start.

The car just clicks and doesn't start.


You may need to drive the car back to where you bought the battery. You may have a faulty battery or faulty alternator. When the car is running it should be charging from about 13.8amps and above. If the battery is completely depleted, a jump pack will not be able to jump start the vehicle.

Hope that helps.

I have a problem with a 2008 Dodge Charger, my battery went bad and I had to jump it off to take it and get a new battery put in but now my new battery won't start my car not even when the new battery...

When you jump started the vehicle, it started as normal and you drove to a shop to have a new battery installed.?? Correct??

1. Who removed the old battery and installed the new one?

2. Did the car start normally immediately after the new battery was fitted? How frequently were you able to drive the car on the new battery before the problem you described appeared?

3. Has anything been done to the vehicle since the new battery was fitted.?

Hello, day before yesterday my car wont start i turn the key it made one click noise nothing else i tried again same a boost and car started worked fine all day ,, took car to autozone auto...

You were told the battery and alternator was good? how did they check your alternator? did they perform a load check on the battery? you should check the battery out yourself with a cheap digital should read at least 12.5v..if not the alternator is not charging your cars battery that is why a jump keeps it going for about a day and then your battery will drain and it wont start again until you get another jump; or your serpentine belt is worn out and slipping. Do the windows fog up in cold weather only?...because that would be normal with you sitting in your car for awhile with a dirty inside windshield and trying to start the car for long just could be a coincidence. The only reason your car started that time in haste was because it sat overnight and it gave the battery a chance to charge up somewhat and it barely had enough juice to turn it over. have AAA or someone jump start you, then take a voltage reading right as it starts and you should see the voltage rise to about 14.5v then stabilize slowly down to 13v or>. this voltage is being properly regulated!

Could be your alternator. If you can get it started again. Try to have the alternator checked out.
