This may seem weird but I drove my car the other day, drove just fine, put it away in the garage with the windows down for a change (wanted to let it vent out the vapors from sitting in the shop at Imagine Auto, you know the typical gasoline/oil/shop smell).

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1Original post

This may seem weird but I drove my car the other day, drove just fine, put it away in the garage with the windows down for a change (wanted to let it vent out the vapors from sitting in the shop at Imagine Auto, you know the typical gasoline/oil/shop smell). Car sat for what 4 or 5 days and I went to start it today and the battery was almost completely dead. I did not leave the keys in the car, I did not leave the hatch open or any lights or stereo on, as I said the only thing different from what I would normally do is that I left the windows down. Any suggestions? I have the car on my trickle charger now (the one I picked up from Ralph Boothe last year - Ralph is recoving from knee surgery btw, please wish him well in that topic thread) and after several hours on the charger it doesn't seem to have built up any battery power, as if there was still a drain on the system. What the best way to check for how much drain is on the system, an voltmeter across the positive/negative terminals of the battery or something else?

POST 2Original post

Partial answer is that from my experience lowering the windows has no impact on battery life. Trickle chargers will take more than 24 hours to get you back to normal. I'd suggest a short somewhere as a WAG.

POST 3Original post

I park mine in the garage with the windows down, it makes getting in and out easyer. Went on vacation for 2 1/2 weeks car started right up.

POST 4Original post

I also park in my garage with the windows down, and no battery problems. I doubt that is the source of your issue.

POST 5Original post

Funny you ask as I was pondering the same. I parked my car with the windows down for a few days and when I tried to start it all it gave was a couple of clicks and dead. I jump it with cables and it started right up. I shut it off and put it on the charger for a few hours and it has been fine since. It was the only time I have parked it with the windows down for more than a couple of hours.

POST 6Original post

Was the car locked or unlocked while it was parked with the windows down?

POST 7Original post

To check for current draw, first you must have a fairly well-charged battery . Then disconnect either battery cable and connect an ammeter between post and cable. Many multimeters will be damaged by current levels above a few miliamps so use a good meter and start with it set on a higher range scale. You are looking for low levels of current, hopefully, so you may need to work down to miliamp ranges anyway. Does your car still have its original battery ?

POST 8Original post

Unlocked, I know because my son opened the car door at one point but I fully closed it, it was not ajar or anything.

POST 9Original post

Yep still has original battery and there have never been any signs of battery weakness before, the only issue I've ever had in that regard is my ipod staying on and running out of battery power because the car shut off the most ring and the ipod stayed on for some reason (I suspect a flaw in the Dension software as others have reported same issue) Oddly enough too when I took the batter cover off there was a piece of duct tape over the terminal on the passenger side. I took it off. I suspect it was put there by my dealership when they last worked on my car to see if I had pulled the battery cable off at some point or something, I don't know, but anyway I took it off because I didn't put it there... Anyway still on the trickle charger, I am out of town tomorrow so it can charge all night tonight and all day tomorrow and I'll try it tomorrow evening and see what I get.

POST 10Original post

There have been a couple of threads on the forum about batteries discharging when the car was left unlocked for a few days. I have a feeling the MOST bus, and maybe the CAN bus , stay on or in a low power standby mode while the car is unlocked because more features stay "ready" to act for you to get in and drive away. For example, the window motors that lower the windows slightly when you pull the door handles. Also, the Dension is on an always-on connection, and gets switched signal from the MOST bus, so if in fact the MOST bus does not completely shut down if the car is left unlocked then it's possible it made the situation worse. Also, the remote RF receivers don't turn off after 5-days when you leave the car unlocked... this is one of the battery conservation features the car has. I know that's not an issue here since you said it was only four days, but in the future, you should definitely lock the car when you plan on parking it for a while.

POST 11Original post

That's weird, because I can leave mine unlocked in the garage for months, and it's fine. brad

POST 12Original post

You know all this, but I suggest seeing if you have a cell going bad by having a diagnostic test at any facility capable of such a test. Not to wish it upon you, but that is my guess based on the probable age of the original battery.

POST 14Original post

I always leave mine unlocked in the garage. Windows always up to keep mice out. Maybe it is just time for a new battery ? 2006 right?

POST 15Original post

No I think something is up, charger was on for 24 hours and it seemed weaker not stronger. I pulled the cable off the battery and my meter only goes up to 300ma it instantly pegged 300ma so it is drawing more than that. How much should it draw in a shutdown state btw, anyone know? So I left the cable off the battery and have the charger on the battery now. I will leave it on for another 48hrs while I am away and when I get back try slapping the cable on and driving it up to the dealership to see if they can find the short, but I suspect something has a short of some kind unless that kind of current draw is "normal", again I don't know what the normal draw should be, but it was more than my meter would measure. Thankfully I am away on business for a couple of days and don't need the car for anything at the moment anyway...

POST 16Original post

This could be useful. http://www.planet-9.com/cayman-tech/18024-cayman-battery-load-when-parked.htm

POST 17Original post

Well we know my car is drawing more than the 15ma in the idle state the L8Apex measured on his car, more like the 1.7A or something. I wonder if something is the key switch is fouled up and it thinks the key is in the car or the ignition is on when it really isn't? Hopefully the battery isn't ruined and I can get it charged up enough to start and drive the car to the dealership and let them troubleshoot it. It's under warranty might as well make use of it...

Does your car have a Dixie flag painted across the roof? Ever use it to jump across rivers as you flee the law? Sorry for the temporary thread jacking!
