I used its "O" connector to mount on the Batt terminals and just plug it on the tender for easy on/off attachment.

The idea of fresh oil for storage is based on the belief that used oil will contain moisture and contaminants that the engine won't like sitting there for four months.

agreed with Bruce, trickle chargers are usually used for reviving dying batteries.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored.

Tires inflated to max sidewall pressure (never had a flat spot problem, not that didn't work itself out in a mile or two).
Hey everybody! The weather is starting to change and its about time for the Porsche to stay in the garage. I play on letting it sit until April 2011. I have read a few threads regarding storage already. What do you all recommend since it is my first winter with the car. I was thinking:
-Change oil
-Clean interior
-Fuel Stabilizer
-Wax and Cover
-Disconnect battery
Am I missing anything else???
That is a possibility, I don't really like the idea of leaving jack stands under the car for that long. I could always roll the car every month or so...
Ive used this for 4 winters.... no issues. Just clip on and forget it. I used its "O" connector to mount on the Batt terminals and just plug it on the tender for easy on/off attachment.

If you read the owners manual Porsche recommends inflating the tires to some really high PSI (50+ i believe) for long storage intervals to avoid flat spots.
Ryan:
Not sure what you get for moisture (humidity) once the weather gets warmer, but before you start driving. I hang a "damp rid" off the steering wheel adjuster, this will absord any moisture and prevent mold. Also, the mice love the cornstarch in the colored German wires, so I place mouse traps and Bounce dryer sheets, on the wheels, in the front radiator areas, in the tail pipes, under the car in the air intake areas, etc. Done this for 5 years and no problems yet. BTW: the Porsche trickle charger (a bit pricey) works great, simple plug it in to the outlet and the cigarette lighter...Oh yeah, put some gasoline stabilizer in and run it through the fuel system before you shut her down. Lastly, I put my baby away with a fresh oil change.

disconnect your battery but make sure to leave your hood open.... if you disconnect the battery and close your hood you may not be able to pop it open again.... I usually just put an old wrench in the locking mechanism so it cannot lock accidentally....
From what I have read, DO NOT PUT YOUR CAR AWAY ON JACKS. It is not good to leave the suspension unsprung for that 4 or 5 months period of time. It may keep the tires from flat spotting, but you can resolve that situation much easier by just overinflating the tires. Don't pull the emergency brake, just put blocks on both sides of one tire. That will keep the car from rolling. Then, every week or so, you can easily just push the car forward and back a foot, and that will keep the tires from getting flat in a spot.
In any case, if they do get flat spotted, for whatever reason, it will generally smooth out after driving it around in the spring for a couple of hours.

Ryan:
The bounce dryer sheet keep the mice away and while the humididty is low during the dead of winter (around here), once things start to warm up, March /April, (and we usuually get a January warm spell- which hinders the snowbaord season) all that moisture goes somewhere...the damp rid will absorb it all before you get her out of storage and begin driving her. In my experience, the window is cracked to allow the trickle charger cable into the car without pinching, and I have nevere had a problem with the hood.

My Owner's Manual states for long term storage to over inflate tires to 58 PSI. I have done this the past 4 winter hibernations, and I have never had my tires (PS2's) flat spot.
I also do a few other thing that I think help:
1) First Saturday of each month in storage, I move the car by hand 6-10 inches
2) The last month of storage, I increase interval to weekly
3) Inflate tires with nitrogen
4) Park on hard rubber tiles from Home Depot (like you might find in a health club weight room)
Modern tires rebound and reverse flat spotting pretty well, in the Spring with the first good heat cycle, regardless.
I stored my roadster in the winter for 8 years. It was kept underground, if that makes a difference. My experience:
Don't disconnect the battery (interesting piece in the current Excellence on this).
Battery
maintainer
,
not
trickle charger. There's a difference.
Full tank of ethanol-free fuel (I never bothered with stabilizer for that length of time, although I use it in my snow machines).
Fresh oil.
Tires inflated to max sidewall pressure (never had a flat spot problem, not that didn't work itself out in a mile or two).
Plug the tailpipes if there's any chance of mice where you are.
Clean and cover.
When you get it out in the spring, don't forget to unplug those tailpipes and lower your tire pressures. FWIW.
I didn't have a chance to see the Excellence article although I was at Chapters twice this week... But what's the problem with disconnecting the battery? I thought this was a good practice.
Now I'm confused... Fresh oil prior to storing or after....? Both make sense in their own way, but what's best?
I would change the oil BEFORE storage. Here's the rationale: During any period in which you are driving the car, there is a certain amount of contaminants, moisture and acid that build up in the oil. This will vary on the conditions in which you drive the car, the length of your trips, etc. By changing the oil right before you put the car away, you are finally lubricating the internal parts with a fresh bath of clean oil.
Think of it this way. You are out working in the yard, getting all dirty and sweated up. You know that you need to take a shower before you go to work tomorrow. When will you shower and get cleaned up, before you go to bed, or after you get up? Same answer for your car.

The idea of fresh oil for storage is based on the belief that used oil will contain moisture and contaminants that the engine won't like sitting there for four months. Might be overkill, but that's the logic.
The Excellence piece actually has a section called "Don't Disconnect the Battery", believe it or not, and uses a 996 as the hypothetical case. Too long to summarize here, but the risks revolve around the DME losing all of its adaptive parameters. This can lead to misfires, raw fuel entering the cats and a bunch of other ugly stuff. I know some guys have done this without problems and will chime in to say so, but I wouldn't do it on a bet. There's a reason my tech connects a stable power supply to the car before he works on almost anything.
Smart people will mock me for paying too much money, but I just bought Porsche's battery maintainer instead of fussing about it. It plugs into the cigarette lighter and turns itself on and off as necessary. Dealerships sell them.
A trickle charger feeds your battery a steady supply of current whether it needs it or not. In extreme cases, I've seen guys boil motorcycle-size batteries dry with these, and even blow them up. A maintainer monitors your battery's condition and rate of discharge and supplies current to replace what's lost as needed.
Any chance y'all are overthinking this? My solution has always been to wash the car, stick it in the garage, and take it out for a 20-minute drive every three weeks or so. Never any problems with batteries, flatspotted tires, or anything else.
Ryan, the link I posted is not a trickle charger but a maintainer.... I said trickle charger originally but meant a maintainer.... agreed with Bruce, trickle chargers are usually used for reviving dying batteries.
This is the most user friendly battery maintainer that I found... Plugs in the cigarette lighter and the wall... no need to put adapters on the battery itself.
What do you guys think of this one?
http://www.automotion.com/genuine-po...aintainer.html
You are right! Correct me if I'm wrong, I do not need the clamps if the battery is still hooked to the car?
http://www.suncoastparts.com/product...y_Code=996elec
You do not need the clamps. Just plug into cig. lighter....and close the door.
I plug in every chance I get, unless I know I will use the car again that day. Plugged in the entire hibernation period.
You can get the same "maintainer" charger that has the Porsche name on it for a lot less on Amazon.com. The C-Tek unit is the same one as the Porsche unit.
Me, I drive my car about 20-30 minutes every 2-3 wks. Use a battery maintainer and I bought some 2 inch styrofoam insulation. I broke it up into 2' X 2' squares and my car sits on them for the tires. Keeps them from flat spotting and keeps them warm, too
You'd be surprised! Even after a typical 320 miles drive, I plug in the cars, and the Porsche battery maintainer does its work for about 12-24 hours fully charging up the battery.
If the car is off the "juice" for a couple weeks (one of my storage garages does not have elect.) it will take the battery maintainer 3-4 DAYS to top up the healthy battery.
Actually, I find that my C4 feels at the top of its game during the winter. The cold air makes it feel more powerful and on winter tires I feel more confident in it than I do in my AWD Infiniti crossover.
I went with the one from suncoastporsche.com. I'm waiting for mine in the mail as well....
It really hurts me to put this car away, and drive a 97 accord for the winter...
But it's time to save more money and stack up a few parts for the spring! That's always an exciting feeling of knowing you have various parts lined up for install...
Is it spring yet?................................................................
Today i got the battery maintainer and I hooked it up. Looks great to me. Only $20! Check it out.

I hate to rain on your parade, but this looks like a trickle charger. See where it says "2 amp constant output"? I wouldn't use it on my car, certainly not for weeks at a time. Sorry, and I'd be happy if I was wrong, but I don't think I am.
I am looking at the box here and it says "Battery Maintainer.. , Maintains batteries fully charged over long storage periods and during cold weather; includes reverse-polarity and overcharge=protection features." I guess I'll let you know when the winter is over.
