2nd Battery

RE: 2nd Battery
Thats where i would start, with a larger output alternator. I know many years ago, me and my buddys used to run Warn 8,000 Lb winches on our Jeep CJ's, as well as 3-5 KC Hiliters, it put a strain on our batteries. I believe we replaced stock alternator with higher output ones, and also put in bigger batteries. Never did 2 batteries tho, but wanted to.

A higher output alternator will work. Try a Optima Yellow top battery before you do two batteries. Yellow tops have a high reserve capacity, like a maqrine battery would, only with more cold cranking amps.
