I would say my battery is pretty old. I bought a 2006 unlimited with 700 miles in 2008, I don't think anyone ever touched the battery. So its 6 years. I guess its time, I have also had 5 times problems with the car not starting at all, dead. The first time it was under warranty and was 2 weeks at the dealer. That time the remote did not work and the key did not let me into the car without alarm. The car did not start, did not recognize the key. I have no clue what they did, but I think they changed the ignition part. For me its an issue with the RCM. However after 1 year again, car does not start, the lights went on, ignition just a ticking, another time the car totally dead. I disconnected the battery and connected it back and yeahhhh, everything worked again.
So back to my new issue:
I guess I get a new battery, where I find a good one and what brand would be a good one? I know its a H6 48, right?
Thanks again for all your help, I love this forum, I learned so many things......
