Hello:

I bought my Max when it had 64,000 miles. Now it has 104,000 (it's '97)
I have basically had the car for 4 years, 40K miles. Although I don't have any problems with the Battery, I was wondering when should I change it. I didn't want to wait till one day the car didn't start, but at the same time, everything looks fine right now.

I don't have any Sound system, etc, pretty much all stock.

How long have you guys gone with your battery? (miles/years)

 

no reason to change it if its working properly. You'll see signs where the battery is weakening. My alternator when bad at about 70,000 miles, so i switched that out along with a new optima red top battery. if u do chose to switch it out, the deep cycle batteries rock for our car...and comes with a 7 year warranty (3 years replacement, 4 years pro rated)
