Battery issues

On Friday last week I had the Jeep all packed up for a road trip to Disney when I went to start it and it only clicked. Shit. I had just drove it home from work about an hour ago with out so much as a hiccup.

Anyway, I pushed the Jeep into a safe spot and loaded up the other car and hit the road. When I got back on Sunday I immediately tried to jump the Jeep with a set of cables to see if it would hold a charge once started. Well the only cables I had were crap and couldn't carry the amperage to start it. It also seemed the battery wouldn't take a charge after 20 min of jumping so I took it out and got another. The terminals and battery bracket had mild corrosion and powdery build up, but nothing too bad.

I put the new battery in and it worked and started fine. I also changed the positive terminal and cleaned the neg. Now today I pop the hood and I see that the corrosion has started creeping back in again. Both the positive, negative and bracket hardware has that powdery buildup on it. Very little at this point, but that doesn't seem good after only a few days.

What is going on here? What can I do to keep this battery and connections in good shape? Why is there a buildup on the bracket hardware as well? I can't imagine why that would be happening.

Thanks!

Clean both terminals and connectors with a wire brush. Use an anti-corrosion compound on the terminals and connectors before reattaching. (Vasoline works) Make sure you tighten the connectors enough.

Any parts store sells a spray terminal coating that works well. I use it on all my bAtteries. Clean them first.

Thanks everyone. I went out and bought some silicone spray and covered the terminals and screws. I will check on it again in a few days.
