winching killing battery

INFO:
-I have a warn 9500
-No problem with the jeep ever starting becouse the battery

Last night I was off roading with my some of my buddies and we got a f-150 stuck bad in a pit (I know damn ford right). So got out my tow straps and ARB snatch and hooked everything up to pull him out. While I was pulling him out the battery started dying (yes jeep was running). So I had to put on the gas while still winching. Well got him out of the pit and my jeep ran fine after that. I guess the question I have is do i need to get a better battery like an optima, get a better alternator,or run duel batteries.
Thanks for the help.

Yes winching even with motor running can kill a battery. Been there, done that. Screw the Optima, the old ones were great, the new ones are junk. If you want a real good deep cycle battery that will survive, go to NAPA and get their Excide Jell battery.

There are people who swear by Sears Die Hard Battery. I think the NAPA battery is the best choice, but it is also $200.00 whereas the Die Hard is probably 50% of this.

Just go with a quality battery, and charge it with a battery charger if you drain it too much. I don't think too much of Optima batteries, personally...even the old ones.

If it's worth doing, then it's worth overdoing.

I think your alt kicked out. And it be because you batt is old?? The alt shut down is a good thing. it means to me I won't kill an alternator from over taxing the unit. Pulling for more than 15 seconds is not advised in the instructions in most winchs due to over heating of the winch motor. mine kicked out one night and i stopped winching for a min and it came right back on.
Most winches pulling more 2000lbs pull more then 200 amps as well. No single alternator on Jeeps is going to keep up with that.

You need a deep cycle battery. That why it kept running down under heavy load. Yes it will still do it with a deep cycle, But not as bad and they are made for it. I run a blue top D34M, All my other jeeps and vehicles have red tops. Only had problem with one, But for the price, Ill replace my blue with a DH, Has a way better warranty. Good luck

MOPAR!

If you want a quality battery at a good price go O'Reillys for their Extreme AGM battery. It's only $139 and can handle winch loads very well and will also handle the shock of off-road driving too.





Extreme AGM (Absorbed Glass Mat)

* 84 month warranty
* 3 year free replacement
* Great for high powered accessories and high vibration applications
* Spill proof and leak proof - mount in virtually any position
* Sealed construction eliminates terminal corrosion
* 100% maintenance free design

Any of the high capacity AGM batteries are a better choice for a Jeep, much less a Jeep with a winch.

I run the East Penn Deka AGM battery as sold by O'Reillys with their Super Start Extreme AGM name for about $140 and it runs my Warn M8000 without breaking a sweat.

Edit: I'm a bit slower than sportcoupe, above. He said it well!

Since you were winching at night, were you running any aux lights and head lights, etc. Lights are additional load that you would not normally experience during winching in day light. Just a thought.

Depending upon the exact situation, this may work a time or two, or it may not work at all. After I winched my battery beyond its limits, it was never the same. No matter what I did, it was a weak battery from that day forward.

install a hand throttle, set your rpms up when winching and get an upgraded alternator coupled with a better battery if you do a lot of night riding with lights and winching involved.

Well, by "quality battery" I refer to such models as the ones listed above. Furthermore, I haven't ever had a battery that couldn't survive being drained down a bit, but if I was unclear when I said "too much" I apologize. I agree wholeheartedly that if you take a battery beyond its limitations, then you may never get it back...however, I also see a big difference between "too much" and "beyond its limits." The former is a reparable danger zone. The latter is not.

Thanks for pointing that out!

If it's worth doing, then it's worth overdoing.
