ONE OR BOTH???

[GORILLA BE STROKINNN]

I'm about to go on deployment again and I was wondering if I unhooked one battery would that open the circuit to where that is all I have to unhook? I was thinking about buying a quick disconnect (screw type) lead for the negative for one of the batteries if it would wrok with just one lead out of the 4 disconnected.... does anyone understand and does anyone think it will work.... also it will be hooked up to a set of battery tenders...... and will just sit in my driveway and my girlfriend will be watching it for me.....she wont drive it.... she drives a jetta so she wont drive it......

No, you have to unhook both.

Yup, if you only undo one, the truck will still draw power from the hooked up battery.

Now if they were wired in series, that would be different.

Untrue....They have to be wired in series otherwise it would take 2 alternators to charge them one for each battery...... I'm pretty sure they dont have to be both hooked up but I want to make sure...... I just need to figure out where to put the quick disconnect....

For your truck, a parallel battery system, unhooking one cable from one batter does nothing. The same cable on the other battery takes up the slack.
Usually quick D/Cs are on the hot side.
I looked at some a while ago that were made for motor homes, and was gonna do them, but never did.

jesilvas is right.
these are a parallel curcuit system to keep voltage at 12v.
If one is unhooked, the other will continue to power the system.

Trace the wiring. There is seperate ground wires but they share one common positive wire.

Wrong. They aren't series batteries they are parallel. they can work without the other one present (but not a good idea whatsoever). Disconnect the hotside of each battery and you should be fine.

Why would you even disconnect the batteries if your going to have a tender on it? I personally would rather have the small draw that the vehicle electronics create than nothing at all. Just my .02.

Just wondering why the hot side instead of the ground?

This might be a dumb question, where are you deploying to ?
