Here is what I am wanting to do. I have the KC 6" 130W on the windshield and the KC 6" 100W on the bumper. I am wanting to add the Rally 800 130W 8" light from KC, will the battery handle it. The other electrical loads are a Trail Guide GPS, Cell Phone Booster and CB Radio. Please keep in mind that the other junk is not full time use.

 

With 4 lights @ 130w. And 2 lights @ 100w = 720w. So about a 60A lighting load. Now you also have to consider the load tha your Jeep requires just to operate. And that also depends on what you are operating in the jeep. If I remember correctly, this could be up to a 60A load also. So now we are up to about 120A total load. Some Jeeps came with a 140A alternator. And some came with a 160A alternator. Even though either one will be able to handle this load. It's still approaching the upper capacity of the system. Hope this wasn't to much information?
