Ask the mechanic to test for parasitic draw. That case seems a bit extreme but tat could be your answer. Of course the obvious things like dome light, glove box, hood light, any courtesy light staying on. But the fact that it draining the battery in 5 hours seems to indicate something other than a light. Take a look at the power windows. I have seen a power window switch stick in the up position. This will quickly drain the battery. Here are a few things to try. One, remove the negative cable from the terminal and put a test light between the cable and the battery post. If the light glows, there is a drain. To find what circuit is causing the drain, remove one fuse at a time until the light goes away. Then, install them one at a time. When the light glows there is a drain, when the light is off, the bad circuit was removed. You may not get the light to turn off. In that case, it means that there is a drain in some other circuit that does not run through the fuse panel. First place I would look at is the starter. Starters have been known to short out at the solenoid and cause a constant drain to ground. If all else fails, replace the battery with another know good battery. You may find that the battery is indeed the culprit, even though it checks good. Good luck.

Rather than assume, why not check the alternator? If an alternator is not functioning properly, the battery can only remain fully charged if the alternator replaces the electrical energy that has been used. Test the system to determine if there is an electrical drain, but start with the alternator first.


What is wrong with the battery if it wont stay charged with a new alternator on a Chrysler 5Th avenue?

Your alternator is probably rebuilt and not really new. I have had this problem several times and I have bought a new battery and alternator. The alternator keeps your battery charged and powers your electrical system, so even when driving you can lose all power in the car from the alternator draining your battery. Take the battery and alternator to an auto store and they will test both for free. Ask them about the difference in a rebuilt alternator and a brand new one. This is a very common problem.

Check the alternator. If the alternator is not generating enough electrical energy to run the car AND recharge the battery you'll always have a low battery. If that's not it try to find something that is being left on that's draining the battery.

Why won't a 1994 Chevy cavalier start unless it is jumped. The ABS makes a clicking noise and we have changed the alternator.?

Generally, if a car engine will not turn over without a jump start, the battery is not charged. Either the alternator is not charging it, or the battery has failed and will not hold a charge. Since you have replaced the alternator, that leaves the battery. You can have your battery tested at an auto parts store before buying a new one. It is also possible that there is something draining your battery while the engine is off. The clicking noise from the ABS indicates possible electrical system malfunctions that are best diagnosed by a professional mechanic.

When you charge battery and will start but drive and cut off and wont start back 91 Chevy cavalier battery is dead again?

The battery only stores electricity, it does not create it. The alternator puts back the energy that was used by the starter and also provides enough electrical energy to keep the accessories running without draining the battery. If the alternator isn't operating properly the battery will discharge. Many auto parts retailers will test your alternator for free in hopes of selling you a new alternator or other part that will help you solve your problem.
