whats the difference 12v vs 24v winch

the 24V is typically found on military vehicles. I'm no mechanic or know-all, but I don't know of any late model civilian vehicles (read: cars light duty trucks, etc. not big rigs or such) running 24V

In *theory* the 24v will draw lower amps.

Ohms law - (quick and dirty translation) in a given application as volts go up amps go down.

Which is why you burn up starters etc by running the battery down (below 10v) and keep on cranking. Volts down = amps up = burn up motor.

Again in theory, you could use the 24v winch by putting a dedicated second battery in series to provide 24v.

In actual practice, I wouldn't bother. There is nothing to be gained by it.

Now if someone just happened to give you a 24v winch, or it dropped in your lap for next to nothing, it might be worth the effort. Otherwise if you are buying it new - buy the 12v.

no...It will only be 24v if you have the batt. in series look at the pic but make the 6v a 12v that is in series(top pic)
 
volts

No. Your vehicle runs on 12v, the batteries are tied in parallel. If you tie two 12v batteries together is series you have 24v. Its kinda like laying two blocks beside each other, still the same height with more weight. Stack them and you have the same weight, plus more height.
 
I saw a write-up about it and they wired up the truck with two new batteries and put them in parallel for 12v. They also did the same truck in 24v with two new batteries. With 24v it was able to pull 1/3 longer before the batteries died compared to the 12v version.

For most people it isn't worth the time. If you need to pull that long just get a hydraulic milemarker.
 
For a temp 24V system you could also look at big rig shops. I am pretty sure some of them use 24V for the starter and then run on 12V. I would think that you are better off just doubling up the batteries in parrallel with a couple optimas or equiv. Then you can also run lights and radios without worry of a dead battery.

If you hook 2 batteries up in parallel, you have to isolate them, or they will drain each other down. .

I'm glad no one told that to my CTD.. As long as they are the same, (to include age), you'll be OK. OEM does it all the time.

Yes, but batteries are never equal, one will die before the other and without isolation it will take the other one with it.
One of the good things about running 2 batteries is having a backup, why not utilize that?

Also, if one battery totally loses a cell and the other is hooked to it, it could explode or cause a fire.
 
So, not knowing much about charging systems, this multi-battery isolator looks like it charges both or several batteries at the same time, yet lets them work independatly?

Yes it basically charges both batteries with the alt. but isolates them from each other in discharge situations and most allow you to start with either battery.

You would run seperate wiring for your 24v winch because you don't want the 24v in you cars wiring anyway.

That isolator is just one I found really quick online, JC Whitney or other places will have them with different current ratings and features.
So I'm not recommending the one in the link, just used it as an example.
