Does anyone know what the battery typ is in the 718 GT4? My Porsche Charg-omatic nas noral battery and Li-ion settings so want to ensure i set it sorrectly. Also I'm guessing the chsrging port is the 12v port in the passenegr footwell. Must say I'm disappointed in the Drievrs Manual as it doesnt mention anything and this is the sort of car youre goign to keep on trickle charge. TIA
Trickle Charge 718 GT4

If it is the same set up as the GT4 981 you will have a Banner AGM battery with c60AH. So AGM setting on the charger. NOT a LiON battery !
If the sameas the 981 GT4, your Porsche will also 'lock' the charging ports after about a 20 (?) minutes after your car is shut, stopping you trickle charging from the internal sockets, I think it was to stop people leaving their phones etc. plugged in to the socket and draining the battery completely while the engine was not running. From Rennlist in the US, I understand that this feature can be coded out by the dealer (in 981 it was called the WG38 campaign and was needed because Porsche supplied a charger with its Lithium battery option whcih then didn't work!).
However most people either open the front and charge the car direct to battery or put in a permanent trickle charge connection. There is another active thread (andrew CS talking about his new to him GT4 and I think he shows how he has done his CTEK).
Good luck with the new car, everything I've read about them sounds fantastic and a nice step forward! Do post a photo. Snowy

Earth to chassis and Positive to + battery post. Far left of image to the right of the suspension turret is the stud recommended by Porsche for earth connection when using crocodile clips. I use the N/S suspension turret which has an unused M6 or M8 (sorry I don't recall which) threaded hole which after removing a small but sufficient amount of paint provides a more convenient earth when using the shorter eyelet cables.

Picture of my 981S so common I believe to all 981 stop/start.
To answer Carl's original question, looking on the Porsche Configurator the only cars that appear to have the lightweight LiFePO4 battery as standard are the 911 Turbo S and [oddly enough] the Cayenne range, although it may have been a standard fit on the 991.2 GT3. Doesn't look as though it's an option on the 718 GT4 though; still using the AGM battery.

Thanks, My Cayenne Coupe Turbo has the Li Battery tooMotorhead said:
Thanks, my understandind is that the 12V port in the passenger well will work for trackle charge purpsoes but USB ports do deactive after 20mins. Works fine on my Cayenne Coupe Turbo when left on.snowy999 said:
Hi there,
I have a 718 GT4 which is garaged at the moment with a Ctek 5.0 that has been maintaining the battery for the past couple of months. However, the Ctek 5.0 has been on the 'car' mode for this time but wonder if a) I need to set it to AGM and b) if I do need to set it to AGM has there been an issue having it on 'car' mode previously?
Thanks in advance.

Tim,
Others will confirm but I’m sure that your 718 will have an AGM battery. If you look at the CTEK 5.0 manual it says that the Normal battery programme is suitable for “many AGM batteries” whereas the AGM option is suitable for “charging most AGM batteries like Optima and Odyssey”, so make of that what you will. The only difference between the two options seems to be the charge voltage - 14.4V versus 14.7V respectively - so I can’t see that you’ve caused any ill effects by using the Normal setting.

Thanks Jeff,
I do remember that a few months ago I equired on this subject but for the life of me I couldn't seem to find the post to review.
I have now switched to AGM but feel better that I hopefully haven't caused any ill effects from the previous setting.
Thanks again and Happy New Year to you.

CTEK 5.0 has an AGM selection, I use that.
The lower middle two lights are lit, the others left and right are not. Car and AGM seemed the right ones to select.

Thank you for this Ralph, it was very helpful.
Given this latest lockdown and the recent ice and snow in our area I’ve not been able to take my car out as I would have liked, so I decided last night to adopt your more permanent solution for connecting my CTek up to the car using your suggestion above and so far all seems well.
Does anyone know why we can’t connect the negative earth directly to the battery? Also if the car goes into the main dealer at any time, should I remove the CTek hardwiring?
My previous car a 992 had a Lithium Ion battery so I had to purchase another charger for that car and it certainly needed it, because of all the electrical wizardry it lost its charge really quickly if it was left for a couple of weeks or more. I seem to be amassing a nice collection of chargers now...
Thanks again,
Martin
Martin,
My Centre fitted the CTEK tails to the battery/top mount post and so I would say don't remove when taking the car to your Centre.
But of course on my previous Cayman S 3.8L, I initially connected the conditioner earth to the battery post; I also had a replacement battery fitted without "coding" it to the car and nothing strange happened on either circumstances. I reverted to the correct method after discussing it with some independent service agents.
As I understand it, the battery earth is part of the battery monitoring system in that it feeds data to the relevant ECU. Attaching a conditioner or charger directly to the battery earth post somehow confuses the monitoring process. It is in all the technical literature and handbook so I now follow that.

Martin,
I have to agree with Ralph and Andrew that there’s no problem leaving the wiring attached when taking the car to any dealership. After all the CTEK conditioner is offered by Porsche as an accessory, albeit relabelled Charge-o-mat.
I think you’ll find that in their user manual CTEK recommend using a body earthing point rather than the battery negative terminal.
