I have used the Porsche charger plugged into my Porsches for the last 9 years.

been checking around to find out the best solution to keep the battery charged, and read the charge-o-mat seems to be the easiest and hassle free.

BTW, this is the first time I've used the tender - the battery is an OEM Porsche battery, only one year old, and has been started and run a couple of times per week.

Phil, if you run your fingers under the car door, you'll feel a notch in the rubber seal that runs along the bottom.

It is designed to work perfectly well in far lower temps than you've experienced, and there is absolutely no need to use a charger on your battery in this case.

The people using chargers are either leaving their vehicles for prolonged periods of time without use, or wasting their money on another gadget because they are **** about their cars.
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.

Just connected the Porsche Charge-O-Mat to my C4S. The cord fits relatively comfortably under the door which closes tightly over it. I know this has been posted in other places, but reassure me that I won't damage either the door, paint, or the rubber sealing molding under the door where the cord snugs against. Do most of you who use chargers over the winter run them through a slightly open window and just switch off the interior lights? I'd do that, but once I Zaino her for the season, I want to put on a cover - not a great idea if the cord's running down the side of the car.
Thanks for any input on this -- Phil
Don't sweat the cord, the rubber gasket/seal won't damage it. Your battery will last at least 5X longer than if you just let the car sit without a tender. Don't drive away in the Spring with it plugged in though. That could get messy....
Yeah, that could present a slight problem. BTW, this is the first time I've used the tender - the battery is an OEM Porsche battery, only one year old, and has been started and run a couple of times per week. How long should it take to fully charge - it's been on for around 8 hours and still showing that it's charging.
Will it really? I've been hooking up my Porsche maintainer because the weather's been so cold in LA. When I went out to the car yesterday (the car had been hooked up for a few days), I noticed that the red light on the plug had turned off.
Thanks - Sean
FWIW
I have used the Porsche charger plugged into my Porsches for the last 9 years. When first plugged in the light will be illuminated. Over time, the light will go out as the battery has reached its necessary charge. After a few days or a week, the light will illuminate again as the battery has been drawn down by all of the parasitic loads (ECU, radio memory etc.). After a day or so the light goes out again. The cord has no problem passing the door seal on the bottom of the door. the seal is complaint enough to accommodate it without permanent deformation.
Now just sit back and wait for the good weather.
WHATEVER YOU DO, DO NOT GO OUT AND START THE CAR AND LET THE ENGINE IDLE IN PLACE FOR "EXERCISE". IF YOU'RE NOT GOING TO DRIVE SUFFICIENTLY TO WARM UP THE GEARBOX, DON'T DRIVE IT AT ALL.
Cheers,
After cycling the "mode" button, the charger has been on for >24 hours and still showing the 2 lights - one for the "car" icon, and the other for the 1/2 full battery icon. I would have expected the battery to be fully charged by now. Should I be concerned or is this normal (I've heard the first time you do this it can take 2 or more days to fully charge.) Do the lights go off, or should I get the light with the "full battery" icon??
Phil - great thing about trickle chargers is that they charge slowly - so don't be concerned.
Depending where your battery was when you started, it could take days.
Every time you open your car door to check, you're probably putting it back a day because of the interior lights!
I put the charge-o-mat on my car and my battery is due for changing. It took 3 days to charge up, and I actually went back out and was curious that it hadn't gotten full yet, so I hit the mode button and cycled the charger off, then back to the car mode and when I did that it switched from the half full battery to the full one.
So my suggestion would be to go through the mode button again and just see if that happens to change it. I'm not sure why mine didn't just kick over by itself. Regardless it seems to be working
Please forgive me. I have never heard of these vehicles needing to be charged. If I were to drive a couple times per week, do I need to put my battery on charge?
No - you are absolutely fine
The people using chargers are either leaving their vehicles for prolonged periods of time without use, or wasting their money on another gadget because they are **** about their cars.
Either way, you sound like you're in the clear and can save your $$$ for something else.
Sean, you make me smile.
I know it's been 'cold' here in SoCal for the locals, but really, your Porsche will be fine.
It is designed to work perfectly well in far lower temps than you've experienced, and there is absolutely no need to use a charger on your battery in this case.
Really, people who live North of us, or in colder countries, are laughing right now at our cold snap, and the way the locals react.
I know, I know, I sound like a sissy. I grew up in Michigan so I've lived through real cold, so I know I am sounding annoying to anyone in truly cold regions right now. I originally bought the maintainer because my battery was draining, but that turned out to be an ignition problem later fixed under warranty. I hadn't hooked it up for over a year and never had a problem. But...a week or so ago, my battery was very weak. The car had sat for two weeks while we were on the road for the holidays. The battery was surprisingly too weak to start the car and the battery is only one year old. I noticed that I had left my cell phone cord plugged in, but without a cell phone attached. I was a little surprised, but not too worried, so I hooked up the charger.
And yes, I waste money on a lot of gadgets, and not just for the Porsche
Phil, if you run your fingers under the car door, you'll feel a notch in the rubber seal that runs along the bottom. My understanding is that notch is precisely for the purpose of the battery maintainer's cord. As others have mentioned, it
can
take days for the battery to fully charge. After all, it's a trickle-charger.
hey guys. thanks for the tips.
been checking around to find out the best solution to keep the battery charged, and read the charge-o-mat seems to be the easiest and hassle free.
just plugged mine in for a couple of days, stayed at "half battery," so i cycled it, and it shows green light! we're a go!
I'm looking for a maintainer/tender and was wondering if anyone knows who has the best bang for the buck charger? I was thinking about the ctek, should it be the 3300 or 3600? Who has the best prices? Or should I just get the oem one for 120?
thanks
