on a different note.... just changed the battery on the green frog today.... i tested the battery myself and it looks like its not holding a charge as well as it should anymore. didnt want to wait until the battery went completely flat so i changed it pre-emptively.
quoted price from dealer = $300 + cost of 1 hour labor + tax
price of replacement battery from walmart (EverStart sealed battery) = $118 + tax +DIY
battery swap was very simple to do. took me 20 mins from start to finish and i was taking my own sweet time. plus the walmart battery has a 3 year warranty versus 1 year warranty on the porsche battery. and walmart battery has higher cold cranking amps than the stock battery as well. also has higher amp-hour rating (battery capacity).
cant believe how much of a rip off these stealerships are. anyone who needs to get a battery change should just pay me $20 to do it... thats how easy it is. one thing you need is to have a battery maintainer handy so you can make sure the car doesnt lose all its memory and go crazy when you disconnect the stock battery from the car.
