Good question on an Optima's heat resistance ? I am in North Dakota, so our climate is a little cooler than say, the deep south or desert south west. A good flooded cell battery will generlly last 5-8 years "Here" while the Spiral cell AGM batteries seem to go 15+. both Optima and Orbital are valve regulated AGM batteries. Each cell has a little pressure relief valve that does not allow any of the electrolyte to get out unless something goes wrong and they have to relieve pressure before the case explodes.
Normally they will not gas off any electrolyte unless you seriously overcharge them, such as putting a big unregulated charger on them then walk away for a few hours, or alternator/. regulator problems where the charging voltage exceeds 14.6 volts. The only electrolyte in there is what is in those absorbed glass mat separators, so they don't have to gas off very much to wreck the battery.
The spiral cell design seems very rugged, no cell connector breakage or plate material shedding off like a conventional flooded flat plate battery.
About the only maintenance I have to do is tighten the lead cable clamp ends a bit every couple years, as lead slowly creeps away from pressure and relaxes it's grip on the posts.

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
