battery terminals

I dunno what one's to recommend. Just don't replace them with the hoop style (like factory). I made that mistake & I hate them.


Also, check your terminal wires while you have them off. The wires can get corroded all the way down. If they are, they really need to be replaced. And get some of that anti-corrosion spray from the parts store (few bux).
 
just get those red and green rings that you see in the battery section at the parts store I have used them for 3 years on all my cars and I dont have any corrosion or acid on my batteries or terminals

Wouldn't build up mostly be due to the battery? What kind of battery do you have? I've had my Optima for two years and theres not even a spec of build up on it.

But clean the terminals and posts with water and baking soda.

Build-up is usually caused from the different metals being in contact with each other. Corrosion is inevitable, at some stage or another. A lead acid battery has lead plates and the two battery terminals are lead. This should be obvious because the terminals are very soft. With steel or brass terminals, electrolysis occurs and corrosion is it's by-product.

Another is caused from acid fumes from over charging. Lead-acid batteries vent hydrogen gas, which is the reason for the vent caps. But sometimes, fumes from the acid mixture can vent past the caps, and find it's way to the terminals.

And the reason your Optima battery doesn't corrode is because it's not a lead-acid battery.

Clean the terminals on the battery and connectors with a terminal cleaner tool (2-3 bucks at autozone), reinstall the connectors and spray the preventive spray. It helps.
