so today I had my first opportunity to use my winch i drove into soft wet ground and the tires just spun and sank i pulled cable and started the can i started pulling the cable in and the second it got tension on it and started pulling the jeep it sucked the life out of the battery and killed the jeep lucikily i put it in 4 low and was about to back out so you guys running winches have this problem do you still have the stock alternator i need to get this figured out

What brand and model of winch are you running and what CCA is your battery rated at? Most winches recommend at least 650 CCA, some more. I have a 1000 CCA and a Warn and haven't had any issues. Some of the cheaper winches and permanant magnet versions pull a ton of amps.

i have an xrc8 and I'm not sure on the battery

I've got a Redtop and a Warn 9000 and I've never noticed a problem. You are supposed to rev it up while using the winch as the alt doesn't charge well at idle, but it still shouldn't have drained it that badly that quickly. Mine is a Limited, so it does have a 100 amp alt stock.

how old is your batt. like it was all ready said you need atleast a 650 amp . i have a 12500 lb that was on my passport and a 1000 amp. never had any go wrong with that set up. yes i said passsport i just my cherokee last friday. did you use the winch for more then 2min. at a time if you did you should stop and let bat,. charge up a bit and keep your rpms up over 1000

I have an xrc 8 as well my battery is a 950 CCA with the stock alternator and have never had a problem. Maybe you should have your alternator and battery checked to make sure they are good and not weak.

both my battery and altornator are under a year old how ever i was noticing that i only have 450 cca so im guessing a problem and i have the stock 90 amp altornator

Your battery doesn't have the recommended minimum cca to run a winch, but it should have ran it longer than it sounds like it did. One thing I've found that lots of guys forget is that if their battery posts aren't clean and tight they will not keep the battery fully charged, also they don't transmit as many amps as they could.

weird...I have a POS autozone battery, prolly like 650CCA and I used my winch like 8 times last sunday (also for the first time ever as I just got it too!)

I did not rev the engine any of the times either, I was standing outside. I used it hard too, and for a long time, almost one winching after another.
