hi roadrat! it's slightly more difficult than any other 'normal' car I've owned, but it's not too bad. open hood. disconnect negative battery terminal. disconnect positive terminal. remove driver's side lower side panel (there are a few screws that hold it in; the tough one is between the door and lower sill; you need a thin (I think 10mm but don't remember for sure) wrench to slip it in there). remove the screws and you can gently remove the side panel. now you need a long extension on a 3/8" socket wrench and remove the bigger (14mm I think?) bolt which holds down the pinch block to secure the battery to the battery box. now hopefully your battery has a strap on it from the factory -- that makes it much easier to pull straight up; not a lot of room in there for your hands!

take it slow and should be no problem. I've taken my battery in and out several times. (don't leave a C4 ZR-1 sitting without driving for more than several weeks -- it seems the batteries like to be killed off quick from sitting in these cars. either disconnect the negative battery cable or keep it on a battery tender like I do)

oh one more thing - when you put the new battery back in and replace the side panel -- take an extra 5 minutes and carefully align the side panel with the door and the fender -- there is alot of adjustment in (play) and if not done right it looks really sloppy when you close the hood and door. the previous owner before me had had the battery replaced by a shop and they had just bolted up the side panel without taking care to line it up and it looked terrible. when I was done with it it looked MUCH better

EDIT -- WVZR-1 just beat me to it lol
