winch+stock batt.=?

[ryguy]

Can I run a smittybilt xrc8 of my stock 710cca battery. I've been looking for the electrical req. online but I can't seem to find it. Any input would be appreciated.

I've run a stock battery for years with a winch with occasional use is fine. If you are going to use it daily or for long pulls then yes upgrade to a deep cycle or marine.

Thanks, that what I wanted to hear

It also depends on the loads you're winching. The larger the load, the higher the amp draw and sooner you will kill, permanantly, a stock battery. That said, I ran an 8274 for years on a only slightly than larger stock battery.

I always thought deep cycle batteries can go through many charge/discharge cycles, but don't like heavy current draws? (Else why not use them for everything?)

In which case a winch drawing 400 or 500 amps isn't going to be good for a deep cycle battery, and you're better off with a second normal starting battery.

Just a thought.

I had been running a stock setup with a winch with no problems.....keep the engine running a little of an idle to keep fighting the amps! Now with the dual battery system.....winching and amps draws are better managed.

The harder the pull the more pulleys i try to add to make it easier on the whole setup!

Hmmm that would explain 2 dead yellow tops,, sheesh

Speaking of pulleys, I was ordering some snatch blocks from Wil today and I got a little busy at work and pretty much hung up on him. I'll have to call him back tomorrow(if he'll pick up). Is it a good Idea to get a winch extension?

Never heard they don't like heavy current draws. That sort of flies in the face of this from Exide's web site.

The amazing new XCD battery provides unparalleled deep cycle power for the most demanding automotive applications. High performance audio vehicles often have one starting battery and one or more deep cycle batteries for energy hungry audio amplifiers, CDs, DVDs, VCRs and game players. The state of the art technology in the XCD is also ideal for SUVs with winches, hydraulic pumps and other power-hungry accessories.

It doesn't really say anything about actual damage when they do pull several hundred amps, though.

That article is comparing lead-acid to lead-acid. I wonder how an AMG or spiral cell would differ? Also, it didn't really say there would be any damage if a large load were placed on a deep cycle battery. It mentioned the use of deep cycle batteries in golf carts. I bet they can create quite a spike in amperage from time to time, probably not as much as a winch under load though.

Ah, yes, I see how it could be read that way.
But a winch doesn't really apply a surge, aside from at first engagement, but rather a steadily increasing load that can grow to 400amps or so and that draw will last for far longer than a regular starting battery is designed to support.
A starting battery is designed to provide 100-200amps for 30 seconds or so.

Another consideration if you do a lot of winching is to look at a high idle switch. At regular idle speed the generator is not putting out much power, maybe 50 to 70% of it's rated output depending on the vehicle and generator. A high idle cranks-up the motor to 1000 to 1100 rpm providing more power to the battery(ies) when winching.

Also be sure to watch-out for the winch/side-post issue; some batteries with dual posts (top and side) do not like pulling big amps through the side posts (I'm pretty sure the Optimas) and can melt the side post internals if this is done.

Thats a good idea. I'll have to look into that, thanks.

Use regular battery for everyday stuff, and a deep cycle on an isolator when you really need the amps. I have a red top / Vision X combination on a 300 amp fuse and a battery brain gold that has worked well for me!
