my red tops are over 5 years old now and never had a problem but when they bit the dirt i will go to the platinum's.
thanks for the heads up on the new red tops

|whiteyj||Careful on the red top's before you go down that road. Search through the threads on here first. There have been a few threads on batteries. Concensus is that: 1. Optima quality has gone into the toilet. 2. Red Top not rated to support winching draws 3. Crowd is heading towards the newer Sears Die Hard Platinum's with glass mat technology.|

yep running two batteries is the best and i really like the red top gel cell batteries and any boat shop has all the stuff you need to hook them up right.
i also just adjust my idle a little higher with the idle screw on my carb to help push more amps to the battery and the mean green alternator i use puts out 180 amps and that really helps at night when running all the lights and winching out all the stuck fords, chevy's, toyota's, datsun's,hummers ( if they are still around )............

Thanks for the replies. I was getting a little neverous when looking at the specs on the XRC8 saying it could draw up to 480 amps and thought I'd see what everyone recommended. I'll run it on one bat for now with 2x rpm.
There looks like there's a lot of space under the hood for a second bat to run in parallel so I might add that option later when I replace my current battery.
Thanx again everyone

Try to think of it like a golf cart motor, its electric, needs a ton of torque and drains batterys fast. We run marine deep cycle batteries in our golf cart, (6) 6v batteries in series for a total of 36 Volts. Now, that big motor is pushing a thousand pounds up hills. Thats a lot of strain.
We expect our winches to pull a couple thousand pounds off from one battery... You can't run 'em in series because it will double your voltage, so I would suggest running in parallel with 2 12v high CCA (Cold Cranking Amp) batteries. And try not to ever run them dead as it damages the individual cells. Pulling with the engine running, high RPM x2. Your draw is always on your battery. Then, the alternator charges as you go.
I always hook up cables and run at a high rpm for about 2-3 minutes when jump starting another car before having them try it. It will use my alternator to charge their battery enough to help start it without 100% of the load hitting the alternator.
Another good example of something with such a load on its battery are digital cameras, throw regular batteries in 'em and they burn up in no time! Use some of the e3 or others like it and they will run the camera 3-5x longer.

|Indy||A LOT of people here (including me with XRC10) run our winches while the engine is running and have no problems. You should be okay as well. Just get a stronger battery like Diehard Platinum from Sears.|

The sudden high current draw from the winch while the alternator is running is more what I was thinking. Voltage regulators don't always catch overvolt once the load is released and this condition can damage the ECM and other electronic components in vehicles.
Would running two batteries at some point in parallel and adding a closed loop charge isolator be the ideal setup?

Not to mention winching w/o the Engine running may well leave you stranded w/ a dead battery, winching with it running prevents this rather well.
Long story short, run the engine while winching unless you have no choice. Keeping the revs. up is also a good plan. (as stated earlier in thread).

Think I already got my answer from the last post here but is it a good idea then to have the motor running while winching to get some output from the alternator?
Only asking because I was wondering what kind of a strain the xrc8 winch puts on the alternator and voltage regulator vs. just running this off the battery only. Obviously I wouldn't want to kill the battery completely to where the Jeep wouldn't be able to start but I'd rather wear down the battery prematurely than the alternator due to cost.
Winching with battery only a real option or is the alternator spinning an absolute must have for the extra amperage?

Such a winch nees up to 450A under full load.
A stock 66Ah battery will not be able to start the Jeep engine after winching for 5-6 minutes when you dont run the engine with higher RPMs while you winch. With about 1800-2000 RPM (alternator max. performance) you can winch some minutes longer.
The winch needs up to 450A. Changing a stock 90A or 117A alternator to a 200A alternator gives you only 1-2 more minutes before the battery is empty. IMO a good and big (deep accle) battery is more important than a bigger alternator.

|Jeepsr4me||Your battery was not up to the pull. More likely it was weak to begin with. You can get a larger CCA battery. Or run two batteries. There are setups for this in a boat supply place. If you gonna do a lot of winching go the 2 battery route, if not get a new higher CCA battery. Also there are some better alternators out there. Putting out more amps. Do a search for upgraded one. They come out of other cars but cheap and at most junk yards.|

winch drains battery
so i just got the smittybilt xrc8 winch. i put the thing on mounted it up and got it runnin. i went out the the hills and got stuck to test it out. i started winching and it just drained my start battery to the point that my tach turned off. it eventualy got me out after having to stop and go but i was wondering what the best solution for this is.
PS can a deep cycle be charged off the same charging system as the start battery
