I am wanting to get a battery tender since I only drive the truck a couple of days a week.
Is the Battery Tender Jr a good option for these trucks? If not, what are you using?
If your driving the truck a couple of times a week, and more than 5-10 miles at a time...you should be good. I say all this with one disclaimer...unless you've had a problem with dead batteries in the past. Battery tenders are more for vehicles that are stored more than they move (classic hot rods, motorcycles in winter, etc...). I've left my truck sitting for a week at a time without battery issues. But then I put 500 miles a week on my truck when I do drive it.
My float voltage now is at 12.4. I was hoping to get as much life out of the batteries and my FICM as possible. When I do drive it, its usually a 100 miles round trip.

You should be fine, with that kind of mileage everything is getting warmed up/recharged. Just for the sake of discussion, how old are the batteries?
This is the one i have hard wired into the passengerside battery one thing you need, new battery bolts because they will screwup if you do it this way when i want to chage just set it by the battery and plug it in. Car Battery Tender Plus 1.25 Amp 12 Volt New | eBay

I use a simple Schumacher 1.5 amp like the one below, only mine is older and the mount is different. I think .75 amp might be a little light for 2 big batteries and I preferred something that permanently mounted.
I also have a Battery Minder for my deep cycle battery. It is supposed to use some high frequency technology to prevent the battery from building up sulfates on the plates. You might look at something like this one.
If you're driving the vehicle enough, the battery shouldn't be a problem. Where I run into trouble is if it sits for more than 2 weeks, or when I start using it around town. Around town for me is just far enough for the glow plugs to shut off before I'm where I'm going, so the battery never gets a chance to charge.

I will be putting my FICM in tomorrow evening and will check for the date and report back.
But it sounds like the consensus is that I really don't need a battery tender unless I am letting it set for weeks at a time. Which won't happen, cuz I just can't go that long without driving it!
Been wanting to do this for some time now, thanks for bringing it up. Is there a solenoid that separates the batteries from each other when the ignition is turned off? That would require 2 separate tenders if so?

I do not believe so. They are still connected together even when the ignition is turned off.

Nope, they're paired together...regardless of what the ignition is doing. That's why when you load test 'em, you've got to unhook one of them so that a good battery isn't covering up for a weak one. It's also why when you use your truck to jump start a minivan...the van all the sudden has all kinds of power to start with
Wow really. I guess one tender will do the trick then
I have Tenders on my '02 7.3, my '03 6.0, and my E350, all with dual batteries, just one Tender. Hard wired in. I use them on all of my vehicles that have any inactivity at all, boat, buggy, 4 stroke quads and motorcycles.
Very nice SoCal. I have them on all the toys but my truck. I will probably wire it behind the bumper with the block heater that way when I plug it up does both.

That is a cool idea Ed, if I lived in 'Chillinois', I would definitely wire them in together!
LOL, yea its starting to get cold over here. I thought wired together would work till David brought up a good point. What if I just want to have the charger on without the block heater for other than the cold time. Looks like Im going to be installing 2 Marinco plugs now. https://www.ford-trucks.com/forums/1...ry-minder.html
