Battery dies so fast

[pauls81sc]

if your battery is dying when the car is just sitting in the driveway than there is probably something drawing power even when the car is off.

If you know how to use a multimeter than you can do a static current draw test. Its pretty easy. Set the meter to DC amps, separate the ground wire from the battery and connect the meter in series between the battery and the ground cable. Anything over a couple hundred milliamps means you have a problem.

My mom's brand new Chrysler 300M had this problem. After about 5 days of no driving the battery was dead. Turned out the glove box light was not turning off.

hmm interesting, ya im gonna have a look at anything that could be drawing power. Did a voltage test and the alternator works fine. And i stayed in it for like 20 minutes driving, stopping, restarting over and over. No problem with restarting the car, but then come back in like 5 hours and its totally dead. so something must be sucking power.

Aka parasitic load. caused by something drawing current from battery with igniton off as stated b4. easy way to find whats pulling current is connent a voltmeters - lead to - battery terminal and + side of voltmeter to - battery cable (disconnected) and note reading. shouldnt be more than .200 milliamps. with voltmeter still connected go to fuse panel under dash and remove fuses 1 at a time while looking at voltmeter.dont mix up fuse ratings. if when fuse is removed voltage drops, you have found which circuit is causing a parasitic load. All done with ignition off of course

i had the same problem and i ended up removing all fuses and still nuttin. was like 2.5v. finally pin pointed the problem. turned out starter silinoid was drawing to much current. minimum voltage to turn starter over is 9.6v.

Good luck

how much volts where you getting ? also volts are nothing, its the amps being pushed.

on problem i ran into when i had my NX2000 was that my alt belt was worn so bad that i was running off the battery (found out after i bought a new one)...so you may want to check the tension on your alt belt and/ or the wear

My battery did the same thing. We knew there was a short somewhere and tore the whole car apart to find out that it was the alternator that shorted out somehow(which was brand new) so we got another one and it works fine now. Good Luck

Did you ever find out what your problem was?

Well. took some time off for vacation etc. Plus started working on some other areas of the car. But now im back to the battery problem. We tried the volt meter test stated above. On my friends car it showed a slight reading, which it should of im guessing since his car doesnt lose battery power, However my car doesnt show any reading on the meter, and yes it was hooked up the same way.

Also i might add, we boost the car, starts right up. We run it for a while. And you can turn the car off and on and start it as much as you want. You come back like 15 mins later, and its dead, dont even try to start the car, even the accessories wont go on, not even the dome light. so i have no idea what the problem is, Any one have more ideas? Im firmly against taking it to a shop, its my project car and id rather do the work myself, but i may have to take it down anyways and get it looked at.
