You simply don't understand, there's nothing different about your Optima that could cause it to be any more corrosion free than the others already mentioned. What you're not getting or refusing to believe is that there is NOTHING different about how your favored Optima battery works vs. any other sealed lead-acid battery like a Diehard, Duracell, Northstar, Odyssey, etc.. None of those are any more likely to cause battery connection corrosion than your Optima battery is. Again... your Optima is a LEAD-ACID battery with ACID-PASTE inside exactly like is inside the others. And again, your Optima is NOT a gel-cell battery.
And even an Optima can "gas" in some conditions which is what causes corrosion of the battery connectors. And those conditions are the same conditions that can cause any battery to gas causing corrosion. However, sealed batteries like all of the above are are not likely to experience corrosion even though in theory it can happen with any of them.
Have I had any battery connector corrosion in the past 25 years or so? Nope. The last time I experienced it was with a conventional wet cell battery which none of the above are.
The below is from Optima's website just to let you know that even Optima says it's not a gel cell battery. If you go to the same page on Optima's website you'll be able to read that even an Optima battery can vent gas just under the same conditions as the other types of batteries mentioned above which is what causes battery connection corrosion. Optima does not have anything different about it from the other batteries mentioned above that would or even could prevent corrosion in the right conditions.
