Gday, Have done an archive search but can't find the answers I'm after. I am looking around for a second hand winch.

What is the difference between a 12v electric winch and a 24v?

Is a heavy duty main battery with 700CCA big enough to handle a Warn 24v 10000lb? If not what would be a more suitable battery?

Well for a start you'd need two batteries to connect in series to give yourself 24v.

You could use the second battery in parallel as your aux battery for most use, then connect it in series to give you 24v for the winch. But that'd be a lot of mucking around at the same time as you're trying to get away from the rising river, stuck in the mud or under the sun bogged in soft sand and trying to find a solid tree for the winch cable.

24v is fantastic to run your vehicle with, as I do, but mine was built for it. Most aren't. Half the current draw and all the benefits of smaller cabling etc. Do another search just on 24v winch and you're likely to find a thread or two.

I've got a PTO winch so won't be guiding you on batteries. Search for winch battery will help get you started on that thread.

24v winches are designed to be used in vehicles with 24v electrics. Stick to a 12v model and you'll be fine.

The only benefit is that you can use smaller cable since the voltage drop is lower. But the cost of heavier cable is offset about ten times by the cost of that extra battery. Stick to 12-volts and use thick cable.
Trust this helps

Quite a few comp vehicles run with 12V electrics and also have 24V winch and seperate alternator to charge it. Means you need at least three batteries, two alternators. The main benefit is a much longer winch time before dischargeing the 24V battery circuit (2x12v in series). Less heat build up and a faster recovery rate of charge. However, it's an expensive set up cost for very little gain for part-time winching. If doing lots of winching, ie every day for an hour or more each time, then you would have to say that PTO is the best option, but then, these days, very few makers have the option of PTO. Then we can get into all sorts of discussions regarding hydraulic winches, wheel winches and seperate engine-power winches, ie Capstain.

Thanks to you blokes that replied. It's a bit clearer now. I will stick to 12v with an auxilliary deep cycle.

Barnesy, If you are wanting an auxiliary battery for winching, then you should use a Cranking battery, not a deep cycle. Deep cycle's are ideal for fridges and light current-drain lights etc, but not recommended for high-amp, high discharge rates, like starting and winching.

Thanks desert, i knew that, i meant i will stick to my 12v battery and also have a deep cycle. Rather than getting 2 cranking batteries to make it up to 24v.
