Just bought a new battery today, $143!!!! Any way i asked the bloke when he was fitting it whether or not he could tell me the age of the old one, he showed me where the code was on it, it said J3. He explained that the j meant the number of months so j = 10th month and 3 meant 2003. So the battery had been in the car since new. The old one was an Exide, so i got the same thing. I thought that five years was pretty good, anyone had one for longer?
