    I know the red top is better for short bursts of power like starting or winching and the yellow is better for long steady draws, like a powerful stereo or bright lights. I have all of the above and will eventually have a welder also. I am thinking of putting in a big ass alternator. Is the deep cycle yellow top really worth the extra $50? Or will the alternator take care of the lights and stereo without any problems?

    That's because I'm the devil.

    I think you should go with a dual battery setup. You would get the best of both worlds. Are you going with an onboard style welder? Or a come along with an inverter. Most onborads come with a hi-amp alternator or an upgrade option. Check your options with dual battery setups at http://www.off-road.com/chevy/reviews/hellroaring/ Click on this to read the article.

    I have the dual from Wrangler NW. And yes, fr8 nailed it. High CCA for primary and starting, deep cycle for long power draws.

    Painless Wiring also makes some nice dual-battery setups.

  5. Here is a link to my set-up

    This is the write-up I did for Off-road.com on my WranglerNW dual battery set-up in my 2000 Z71. It's an awesome setup and I am running the stock battery with one red top Optima. The installation was a breeze and the harness was very easy to work with. It almost looks stock ! <a target="_blank" href=http://www.off-road.com/chevy/reviews/wranglerdb/>http://www.off-road.com/chevy/reviews/wranglerdb/</a>

    one of each?

    So I can run one of each with an isolator?

    If that is the case, then I'll start with the red top and alternator, and later, when my bank account is recovered, I will go ahead and add a yellow top and an isolator.

    Re: one of each?

    I got a Yellow top for $145. Shop around, sometimes it pays.

    Re: one of each?

    When looking for an alternator, check some local starter shops for a rewound one. I got a black powder coated 180A alternator from a shop here in Dallas that is teh exact same size as the stock one for about $130. They sell them over the counter or on ebay. I think they are good quality and worth the money. You can probably find you a local shop that does the same. It would be a LOT cheaper than a new one.

    Just my 2 pennies

    Re: one of each?

    If you have a serpentine belt system - upgrade to an alternator that has the beefy bearings. Wrangler NW has one that pumps out 100 amps at idle with the heavy duty bearings.
    It was so expensive I forgot how much but I will be going to that soon.

    You could run two stock batteries if you wanted to. You could buy the battery tray(one from a diesel will work), then battery, then solenoid, then switch/harness and cables until you piece it all together, but like everthing else in this world it would probably be cheaper to but it at once. Call Steve and Wrangler he will get you an answer to any dual battery questions.
