Why does my F350 PSD have two batteries?
This might seem like a dumb questions, but why does my 2001 F350 7.3L PSD have two batteries? I have two other F250, a 5.4L and 6.8L gassers, which both have 1 battery. Normally I drive the F350, but went on vacation for 3 weeks and of coarse the battery dies. When I went to jump it I notice two batteries. Do I charge both or just one? Is that normal for a diesel? or was the second one a add on?

Thanks Bill, I don't open the hood much, as I routinely maintain my trucks at least every 3 months through my mechanic. I am somewhat handy mechanically, but if it's something new that I never worked on it will take me forever to fix. Also I'm a perfectionist on my own stuff. Free time with family these days is more important. The diesel was bought a few months ago and really didn't take a close look.

I bought the same auto zone batts ! the warranty was better than the optimas but I do like optimas for some applications just not pairs like this set up the chances of both optimas failing at the same time was low and good luck telling them you want 2 because 1 went south .. on the other hand wet cells are easy to make no worky so you can get 2

I'm also running the yellow tops from Autozone. The original Motorcraft batteries lasted 4 years before giving up the ghost. I threw on some Energizers after that, and they died in no time.
I've had the Autozone batteries for a few months now and they seem to hold a charge really well. Had some injector o-ring problems recently that I haven't fixed yet, so my truck has been sitting in the driveway for some time now. I had to use my truck last night, and the batteries were strong as ever. If they last as long as the Motorcraft ones, I'll be happy.

Glow plugs also draw some current (100 Amp??) but it is not significant compared to the starter motor. If anything, the activity to operate the glow plugs helps to warm the battery a bit before starting, making the batteries more potent then if you did a fresh cold start crank.
