I got a Porsche Tequipment Charg-o-mat Battery Charger. I was told that if I did not drive the car daily I should put it on charge. I plan on using this as a weekend car. Is the battery going to die in 5 days of non use? I leave my other cars for longer periods of time without issue. I wonder if perhaps it is the battery that is an issue or perhaps the 911 Turbo S has more electronics that drain the battery.

Does anyone know more?

 

No it will not die in 5 days... do that for a year or more however and it will eventually die. The tender saves your battery in the longer term... You will have no issue for a long while...

A word of caution: Note that if you lock the car and dont move it for more than a week, the key will not open the doors remotely, you will need to unlock with the key (manually), disarm and then enter...

 

I just bought a used turbo and have a tender as well. I travel for work most days, so frequently out of town for 5 days before driving the car again. Have had no issues with it starting up after sitting for 5 days, but agree will be healthier on the battery if hooked to the tender.

Adding a question to this string (i've only used the tender a few times so far since I just got the car): When hooking up the tender does the power cord lay between the bottom of your door and the door sill, essentially "smashing it" under the door when you shut it? I would like to keep my windows up to keep the car air tight while I'm not driving it, but don't want to mark up my door sills when using the tender.

Is there a better way to hook it up?

 

plenty of cushion on the door seal, been using mine for 3 years, no problems.

 

IIRC, if you look closely there's a notch in the rubber seal on the passenger side door bottom.

 

If you have an OEM battery, it might become an issue after a few years. If you have any Autozone or better battery, you're fine.

 

All german autos (Audi BMW MB ) in my experiences have had a tendency for quick discharge batteries and I have been told there isn't an exception with Porsche either.

North east winter months were a guarantee battery replacement..if parked outside.

The Porsche technicians I have contact with recommend a battery tender regardless.

 

Any venting issues with the Porsche tender? Most tenders say to make sure the battery area is vented. If you look at our batteries, well........you can't even see the battery.

 

It's not difficult to get to the battery and it is vented to the outside assuming the vent hose isn't obstructed. Take a look.

 

Smart protection and a good way to keep your battery in top notch. Use a volt meter to test it and if it gets below 12.4 volts its time to hook the tender up (I do it on a regular basis and plug it directly to a quick connect hooked up permantly to the battery). If your battery drops below 12.4 volts it will shorten its life so its important to test it on a regular basis.

 

Yes, there are venting issues.
