My battery is good. The dash is getting power. The engine will not turn over. Could it be anything other than the starter?

You need to make sure that your getting good conection to your battery. If your alternator is fine, as you stated, you might not be getting a good conection. Your alternator may be keeping your battery alive just enough when your driving. Check all connections. Hope this helps.

When ever a batter this new goes bad, it is either because it is not being charged, because there is something wrong with the charging system, or there is a constant drain even when the key is off.

To check the latter, with everything off, you remove a battery cable and see if the is any glow from a test light between the post and the cable. If there is, then you have something on that should not be, all the time. Then you pull fuses and disconnect things until it goes off.

To check if the charging system is not working, the easiest way it is to borrow a battery to get it started, (don't jump start a car if you can avoid it, because you can ruin an alternator when it starts, because it will kill itself trying to charge up that bad battery.) With the lights on, rev up the engine. They should get slightly brighter. Of with a volt meter, see it go from 12.5 to 13.5 volts, or so. If it does not go up, then your battery is all that was powering the car, and it won't last long like that.

Battery does not stay charged has to be jump started each time I go to start the vehicle

There is a defect in the charging system...battery juice that is being used is not being replaced. This is typically caused by a faulty alternator or voltage regulator. Take the car to an autoparts store and have the alternator tested. Most parts stores will test the alternator at no charge. If the alternator is defective it will have to be replaced. Hope this helped you. Best wishes.

Battery Is Draining

start your car and remove the positive battery cable off. if the car dies it is your alternator. alternator can test good but be bad especially on a cavalier. that is the problem i had and the alternator fixed it.

Car no longer starts

Check battery terminals make sure they are not corroded and that the are tightly secured. If all is good the battery is at fault. Replace battery and then have charging system checked to make sure the alternator is working fine. Or you can remove the battery and have it load tested a t an Auto_zone for free.
