Need to buy a Ctek conditioner/charger for 991. I noticed most people use the lighter adaptor. But read somewhere it is better to connect the conditioner directly to the battery leads in order to avoid charging through the car electrics....

- Anyone had a problem from charging through the lighter, please?

- If I am to charge directly to the battery leads, any precaution before I connect the 2 small loops to the battery leads, please? is it a DIY? what happens if I accidentally disconnect one of the car leads of the battery-would this immediately resets all the electronics?

- I know it is ok to pass the ctek wire near the door hinge but if connecting the ctek directly to the battery, is it ok for the wire to press onto the boot seal?

Thank you

 

I just plugged it in the outlet in the passenger footwell and it worked fine.

 

^ same here no issues.

 

Same no issues, didn't use Ctek, got one from Sears works fine.

 

I had one that connects to the battery from before I got the 911 and it also works fine. If I was going to buy now though I would get the cigarette lighter version.

 

I prefer directly to the battery with the quick connector. You will probably need to cut a slit in the loop to install onto the battery bolt, the nuts do not come off. See this link for some help.

This is what I did, no need to disconnect the battery lead to do this, have the pigtail come out under the center plastic piece, easy and neat. But I have also seen many use cig plug in without any problems.

 

I use the lighter in the middle, cord through the door, with no problems.

 

Passenger footwell plug-in with ctek 7002. Extension ctek cord with door closed and locked. All winter long in northeast. Slept like a baby. No hassle.

 

I posted this in Rennlist as well.

"With the red/black leads, Porsche advises against hooking the negative cable directly to the battery. There's a marked, designated ground post to use. Apparently hooking to the negative battery terminal can cause some electronic component issues."

There is a big warning sticker on the battery that says to NOT do that. I leave the plastic cover off and just clamp to the positive post on the battery and ground post to the right of the battery. I would have preferred to use the nice pigtail as I have on other cars but did not want to take any chances.

The manual does discuss charging the battery by connecting to the posts on the battery when it is out of the car. There must be some concern about shorts ad Dwayne indicates.

 

In my 2013 C2s this outlet becomes inactive after about 30 Min. Have my V1
plugged in there. Sometimes I've forgotten to manually turn it off when I
leave the car......

Next morning opening the door it "chirps/powers -up" just like I've turned it on.

Doubtful your charger is doing anything after the socket has gone dead.

Smoker's option console lighter is always active.

 

Same with my V1; however my ctek runs thru the conditioning cycle and maintenance of battery; based on input from ctek, the charger is doing exactly what it was designed to accomplish. Simplistic approach- car started right up after approx 3 1/2 months inactivity and it was quite cold this winter. I was told it was important to lock vehicle which I did.
Call ctek- they are helpful.

 

This is the w/charger plugged into the footwell receptacle?

If there's no juice coming out (not live), how can it go the opposite if the circuit is dead?

I'm not an EE but isn't the power from the charger running in the opposite direction as opposed to coming from the vehicle battery ( which is why the 30min time limit exists- to prevent batt discharge). The ctek clearly shows the cycle is running unless it's untrue. Real world, without starting vehicle x 3 1/2 mo's in freezing temps surely would have hammered my battery- it sure did with my BMW, twice. Could porsche have engineered a diode in the circuit to allow this to occur.
Would like to hear from any EE or similar to explain this phenomenon!!
