Is a 96 amp alt. enough to keep battery charged hen using my 12,000 lb winch with a good battery.

id like to see dual battery setup with a good 100amp - 140amp alternator for good charging.

well the alt tag says it puts out 107, a dual battery is doable thou.

ya have a good starting battery on the one side and a deep cycle on the other side for the winch.

yea it will to a point but in long hard winching it will not keep up i would up grade to 140 amp a least but it also depends on what you do

You could do something like the CUCVs have and just use another alternator. Then just use that separate alt to charge another battery. Thats what I'm doin when I get a winch

I run a stock 105 amp alt. with a Yellow top with no issues. 99% of the pulls will just be a couple feet. In my last 7 years of wheeling I only had 1 long pull. Winched a dead 3/4 ton Dodge up a hill about 75 yards. I did that with a Jeep TJ with a stock alt and yellow top. That was a hard pull and I would have to let the battery catch up but it got the job done. I do use mine pretty hard doing recovery at RCroks comps at Rausch Creek.
No - no alternator can. My Ramsey 9500 draws around 400 amps at full power draw according to the manual. It's like cranking your truck over for a long time. The longer it takes, the more time the battery will need to recover.
IMO the 96 amp is fine.

thanks guys, i was wondering, would i just a lead from the rear of the alt. to the second battery. or is there something else I'll need.
You can spend a little money on hooking up a second battery, or a lot.
The cheap solution is more or less what you're talking about. I'd run a #4 from the positive of the one battery to the other, obviously grounding both of them. Then connect your winch to either of them, and you're good. As long as you leave the engine running, you can run the winch.
The problem is if your engine won't start, you'll run the batteries down real quick and then you can't start the truck. In this case you use a battery isolator, to, duh, isolate the auxiliary battery from the starting one. Both batteries get charged when the engine is running (i.e. the alternator is putting out juice), and you can discharge the aux battery with a winch, lights, fridge, stereo, USB pole dancer, whatever ... and still start from the main battery.
Isolators (and related technologies) are a favorite topic here, do a search. Ryoken is a big fan of a fancy expensive thing; I'm a big fan of cheap solutions like solenoids or at most the diode isolators. Search on either of our usernames, you'll find a goldmine of threads.

As already mentioned a typical winch during a recover draws way more amps than any normal alternator can power, so during a winch recover it's running on the alternator AND battery power. So if you winch long enough it will pull the battery down.
But I will also completely agree with another statement that a typical winch pull is only a few feet, and therefore even a standard single battery and stock alternator would have no issues. Even with the engine not running you should be able to use the winch to pull the truck out of the stuck (if it's the normal short pull) or back over on it's wheels if it rolled. I've seen people use their winches quite a few times in the above situations and they always been able to restart the trucks afterwards.
