Battery question

[smokeless]

I have a 06 powerstroke with about 45000 miles. It always starts and I never have any indication on the dash of voltage problem but the tops of my batteries always look wet. And my cables are corroded. I clean them and it doesn't take long for them to become corroded again. Before my truck was out of the 36000 mile warranty I noticed that one of the batteries indicators showed yellow so I took it into the dealership so they could look at it. I was told that they tested fine and that you cannot rely on those indicators. They could show red and the battery could be just fine. Just the batteries looking wet all the time bothers me. Any help is appreciated and thank you.

They could be leaking. If you have the extra money I would replace them. Especially if your in the cold part of the country. Because if they are leaking then they won't last long in cold weather.

One thing I left out is it looks like the acid is coming out of where the caps snap in on the top of the battery. I have noticed this for probably the last 10-12 thousand miles. I didn't figure batteries would go bad that early. My last couple of powerstrokes that I have had I kept till about 50-60 thousand miles and never had this problem with the other trucks.

Same thing happened to me, I just replaced the batteries.

I have a question though, my passenger side battery was showing signs of corrosion on the positive post, and I asked the guy at Autozone about it and he told me this is due to the alternator charging too much.

What say y'all?

on mine both positive battery cables are corroding.

I just replaced both of mine weekend before last. Changed fuel filters and cycled the key to get the fuel up then it wouldn't start. One of the batteries show a red indicator showing. I threw my charger on it and the charge needle would bounce between full charge and 6v like it had a short. I just went ahead and threw 2 new red top Optimas in. 05 with 63k miles. I didn't want to mess with it with winter coming on.

That's probably what I am going to go ahead and do. I don't want to take the chance of getting stranded somewhere this winter.
