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 use the plug in the left side of the passenger side footwell. Works fine and have had no problems.

 

I use a Porsche battery maintainer plugged right into the consol's cigarette lighter. Close the door on the cord........for many-many years. All good.

 

Same here. No issues.

 

Ditto. No problemo.

 

Same Same

 

Ive always plugged it into the cigarette lighter socket but drape it in such a way that you see it before you drive off. If you use the passenger side foot well socket and have it come in from the passenger door, the cord blends in with the dark carpet and it's possible to forget it's there and drive off without unplugging it (don't ask me how I know

 

Oops! That's unfortunate!

+1 on the cigarette lighter - it will be fine. I run the cable in through the driver's window from the charger mounted conveniently on the wall beside the car.
The Porsche branded device is a C-Tek, btw.

 

It works fine for me too thought the lighter in the middle, cord through the door,

 

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.

 

So is there really any tangible reason to do the direct battery hook up vs the lighter?

 

Not unless you want to.

 

Thank you all... Cigarette lighter then.....

 

Same. Works for me.

 

That was my worry too. What I do is I put the cardboard box that the charger come with on top of the sun roof to remind myself the car is plugged in.
