OptimaJim;
It really is good to see vendors offering help with product issues and I am sure that your presence has helped a number of people sort out common battery issues.
The real world fact remains that Optima batteries (and even most other AGM batteries) do not perform at all well in series applications. In fact, the charge/re-charge/float characteristics for AGM batteries to survive in daily driven and expedition-type vehicles is almost never met even remotely adequately in the vehicles we drive by the stock alternator and voltage regulator.
I have the experience of dealing with dozens and dozens of Optima batteries over the years (had my first one in the early/mid 1990s) and I can tell you that they by far and above the most problematic battery in 24V applications. Some users are fortunate and get perhaps 2 or 3 years of use out of them, but not without a lot of battery swapping (side to side in the vehicle) and maintenance charging to keep them working at a barely acceptable level.
As a result, I do not recommend that AGMs are used in series applications. If I can save someone the experience of spending too much money on an under-performing battery, then I will. And, I'll point them in the direction of something that will give them better service for their application and intended usage. Usually, that means they are going to get heavy duty flooded batteries along with some instructions on how to get the most from their battery purchase.
In parallel battery applications, where the person's budget capable of spending more on batteries, I'll recommend AGM batteries - such as in sailboats, some diesels, and cars.
In marine applications, AGMs perform very well when the alternator and voltage regulator are properly set up for AGM use, and also where a high quality stand-by charging and maintenance system is in place. In cars and light trucks, especially older models, AGMs are just not always a good fit.
A few other points to consider: here in Canada, Optima batteries are very over-priced when compared to other brands and types. The number of vendors carrying Optima is probably closely related to this type of pricing - even low cost vendors such as WalMart sell these batteries for much more than what one would normally pay in the USA. As a business owner myself, I cannot justify stocking and selling a battery or product that I can make any margin on as I cannot compete with big box vendors - I need to survive in business, and Optima battery (and many others - including ARB, Warn winch etc.) do NOT help the situation by only selling to large distributors for marked-up redistribution to smaller businesses such as mine. Pricing policies that penalize Canadians with pricing that can be 2 to 3 times what is paid in the USA is very counter-productive to doing business (Toyota Canada is very guilty of this).
In summary, I have not had very many good experiences with Optima since that one battery I owned in the 1990s (12V single battery application). I do see the yellow tops performing somewhat better than the red tops, but this is in 12V parallel applications and not 24V series applications. I am unable to sell Optima in my business because I cannot obtain them for a reasonable wholesale price point - not that I would really want to offer them, other than they are perhaps the most recognizable AGM battery in the 4WD/automotive market.
I do appreciate you providing information helping people out, but I simply can not recommend products that have, in my experience and that of my clients, weak performance in real world use.
