My 392 sits for 6 weeks at a time and starts right up. Im not sure if my buddy locks the doors or not though. I am currently over seas working and he takes it out every once in awhile to run it around..

There is something in the faq that says if you use the manual emergency key inside the fobic to lock the door it will not activate the anti theft system and reduce drain on the battery for long term storage.

I drive it to the dealer and they say that its cranking 730 amps, the battery is good and can find no problems.
I must have a parasitic drain somewhere.
Has anyone else experienced this after just a week of not driving their car?
Any thoughts?
Hey Wildturkey, be sure to get a charger on the battery as the car will never truly charge the battery back to full unless you drive 3 or more hours straight a couple of times in a row.

If so, that's another trick to put in the book.
No, I don't need to do that...mine works without any issues.

I suggested this to see if disconnecting the IOD fuse would eliminate the battery drain and see if that stops his battery from draining.

If it did, then it would be a matter of tracing down what may be causing excess drain.

If it doesn't then it points to a fault of the battery itself - possibly a weak cell or internal short within a cell.

In talking with a shop that I trust and the AAA guy that jumped my sons car when the battery was dead both told me that a typical battery really only has three years of life. Hot and cold temps wear on a battery greatly. Once a battery is dead it harms the battery quite a bit and you must charge it for 3 hours in order to restore it. SImply driving the car to recharge a dead battery won't do the trick. I typically replace car batteries at 4 year sold as a precaution.

Either the battery in your car really does have an underlying issue or there is something electrical draining your battery. It should hold a charge for much longer than a week. I have gone a month without driving my car and it fires up fine.

This information is from a 09 SRT but I doubt the other models are different.
Parasitic draw after everything powers down is about 30 mA (0.030 Amp).
With the alarm activated, the parasitic draw is about 35 mA so the alarm is not a concern.
At 30 mA after 60 days, a good battery will be weak but should start the car. After 90 days, the battery will likely be "dead".

Question for the OP - do you have ANY aftermarket equipment installed?
Trinity or other tuner?
Anything plugged into the OBDII port? Gauges, etc
Cell phone charger, etc?
A Trinity without the sleep timer set to 30 sec will keep the CAN bus awake and kill your battery in a day or so. With the sleep timer properly set, my Trinity still draws almost 100 mA when dormant so I don't leave it plugged in for more than a few days.
A cell phone charger I checked drew 200 mA even when the cell phone was charged.
Some things to check.

wow! I have gone for over 3 months of not even starting the engine on the original 09 battery and "RMMMMMMM"...........it starts right up, no hesitation. Parasitic is right. My Eclipse on the other hand has a parasitic loss similar to what you are experiencing. My charging system on the Eclipse is all perfect. When running, it puts out 14.6 volts, but if I let the damn thing sit for 6 days...........dead. I've pulled each and every fuse and tested voltage across the contacts with the engine off of course and on an instrument that can detect .001 volts accurately, I can't find the dang problem! It will drive you nuts! I hope that this is NOT your problem!

'11 Challenger R/T

Had same issue when i but a new stereo system in it. I upgraded to a new battery with a larger cca and have not had any problems since. You need to watch out that only a certain size battery will fit in the rear trunk of the car. Went with an Odyssey deep cell battery, #PC1350, cca-770, mca-960, phca-1350. Fit right in. For traveling should disconnect positive cable from terminal, that should help

You need a clamp on meter that will read low current DC. I clamped it around the battery ground cable and measured the currents. You can actually watch as the car's bus shuts things down and eventually gets to the sleep current of about 30 mA with no aftermarket equipment attached. It can take a few minutes to get there.

I also checked some other (GM) vehicles from 1998 to 2011 and the parasitic draw of all of them was in the 20-40 mA range.

This is the meter I have. http://www.extech.com/instruments/pr...d=26&prodid=77
I got it for about $100.

I was told that it was becuase i left my doors locked which activated the security system, which in turn drained the battery dead. Where your doors locked Wildturkey1?? Might be something to that myth, i have left my doors unlocked ever since while sitting idle in the garage and i have not had another dead battery, been 1-1/2 years now since it happend. Hope that helps!!
Hell my car has sat in the garage for over a month with the doors locked and its not ran the battery dead, I just believe chryslers electronics are starting to get like fords was in the 90s. I stated in a previous thread about my step mothers 2011 300c is plagued by electrical problems including running the battery dead. I also had my passenger side window roll down a bunch of times by itself when I hit a bump in the road last year when I went to Gatlinburg, I could also bump the door panel with my fist to get it to do it as well. This is why I like old cars better, you don't have to have a $20,000 computer to tell you that the reason your radio don't work is because you are low on washer fluid.
