I'm going to hook up my winch. What battery should I hook it to?

Are the two batteries connected together with some type of isolator.

Does only one start the truck and the other is aux?

Thanks in advance

They are hooked together like one unit.

They have a big as wire, 0, 00?? connecting the two of them as 1 unit to increase the CCA's to meet the starting demand of the motor.

I will be wiring my winch shortly and will be wiring to the pass side battery as thats where my which gets it power from. I plan to add a large ground to the driver battery thou, and when wiring the ground to the winch I will wire the battery to the frame, and from that same bolt wire the winch. This increases my chassis ground and makes it easier for both batteries to provide power.

I had to do some research for my boat. I put in an inverter to power the boat lift. the lift has a blower that raises and lowers the boat. The blower is 12 amps @ 120 volts A/C for about a minute. I needed a system that would be able to handle that, took lots of reading but works great. I remember reading that it is really hard on batteries to drain them down more than 50% then recharge. If I remember right the best setup would be cycling the batteries to 80% (12.4 volts) is the best setup. Now back to the truck question, running the grid heaters, starter, fuel pump and everything else electrical would probably zap a single battery. With two batterys (the same type and age) share the load and stay above the 80% mark. Batteries charge and discharge differently with age (don't we all ) That is why you replace these batteries in pairs. here is one spot I got some information on, FYI. http://www.windsun.com/Batteries/Battery_FAQ.htm

they are in parallel to give you piles of cranking amps. + to + and - to - to you add amps not voltage. If they were + to - then you would add voltage. But then you would buy two big amp 6 volt batteries.

That's exactly what a lot of people up here where it actually gets cold in winter do...............run two big 6V batteries in series, reather than 2 small 12V's in parallel. In series they don't fight each other, and last a LOT longer.

Stickler where is up here?

I spent a week with "Leaf River Guide Service" a few years ago, hunting Bear, in that area............Fantastic country!
