Porsche 964 c2 battery replacement

[mechagran]

hi there

This is a bit of a silly question (probably) but I do a fair bit of tinkering however I have never (not even on my 67th vehicle) ever had to change a battery myself.

If anyone owns a 964 could they talk me through it - any little things I need to look out for and of course general advice is welcome. I have the battery sat next to car and im sick to death of having to jump it. Tonight is the night!!

Many thanks in advance....

For unintended consequence's sake, I would ensure that the alarm/immobiliser is in its "disarmed" state (which would include the doors being unlocked) and at least one window is wound down before disconnecting the battery.

Thanks for that - I don't think this cobra alarm thing has an "off" setting - just basically doesn't work if the car is dead. It did do one wiesrd thing where it would sort of say"woo-woo" in a pathetic dying sheep sense if the battery was draining. So I unplugged whatever that sensor was under the engine lid.

I hear horror stories of setting fire, welding spanners to bodies (presumably cars) and all sorts of general nastiness....so I thought id ask the gurus.
