I had my air bag light come on a few weeks after getting the car. When I took it in to the dealer and they ran the codes, I got several low voltages codes. Those codes could have been from the car sitting at port for months.
I almost always drive my car at least once a week, but I figure it can’t hurt to throw a maintainer on the car. Per advice of Mike in CA and others and got a Ctek 7002 rather than buying the Porsche branded one. The more sophisticated 7002 still costs less than the Porsche branded Ctek while offering more features and charging/maintaining options.
I also opted for the 2.5m extension cable in order to hard-wire an easy to connect pigtail for regular maintaining. I have not figured out what I’m going to do to have a more permanent solution in the garage. The Ctek has holes for wall mounting. I’ll probably also get some felt tape to wrap the wire that makes contact with the paint.
I hadn’t actually seen the center lock tool yet. Next up, I need to order a torque wrench, wheel guide, etc. to be able to take the wheels off.
I ran the wire/fuse along the backside of the battery and zip-tied to some of the existing factory wiring.
The positive terminal has the handy little area to add an accessory, but the negative terminal does not. I cut the circular wire terminator into a u-shape to make it slide onto the negative battery terminal. The nut on the negative terminal doesn’t come off easily, so I left it on.
The OCD me wouldn’t allow the rubber trim to look unfinished.
