Porsche Cayman battery

[alan.jenkin]

Hi New to Porsche. I need to disconnect battery on Porsche Cayman and then replace it.
Please advise how I do this without affecting the settings/ electronics and Scorpion tracker.
The replace it with no problems.
Thank you
Alan

Post this again in the Cayman Register forum for a better response. Here technical matters on the Club platform itself are discussed.

Hi Alan. Welcome

Unfortunately if you disconnect the battery you'll lose most, if not all, your settings I'm afraid. I don't think it'll effect your tracker as that should start up again once the new battery is fitted but if it's a monitored system it may be worth calling the service to let them know you're changing the battery or you'll be getting a call saying the car has been stolen.

Hi Alan,

As Dan says, no doubt you’ll lose your PCM settings, etc., but in addition you may need to reset the window limits so that the single-touch operation works correctly. You may get a steering sensor warning when you next turn on the ignition, but that should clear once you start driving.

Apparently sometimes there’s no need to reset anything, so perhaps it just depends upon how long it takes to change the battery, and if you have a battery conditioner you could try leaving that connected while you change the battery?

Which model do you have Alan? I can only speak from experience that my 981 stood for 48 hours with no battery in it whilst I waited for the new one to be delivered. I said a little prayer (optional) and put the new one in and fired it up. Everything worked fine. Nothing needed re-setting (e.g. windows or steering sensors) and I had no unwantedlights on the dashboard.

My understanding is that, without recoding, (PIWIS required) the battery management system may not be so effective and may result in shorter battery life. That remains to be seen, but so far it has been OK throughout this year.

987 Boxster and Cayman have no problems with PCM/radio etc when removing and refitting a new battery.
Steering angle sensor requires you to literally drive the car for a few yards tbh, and window closure settings, thats about it

As far as the tracker is concerned and keeping power to it, it may be an idea to connect something like a CTEK directly to the +ve and -ve cables from the battery to keep a small voltage going through it.

Or even booster cables from the new battery connected to the +ve and -ve cables while you remove the terminals off the old battery and move it to the new one.
