I don''t think its apples and oranges.
You said that you had two Optimas last you ten years as if they were super batteries so I then pointed out that I had two batts, that aren''t very well respected in the marine battery arena, last me the same period of time.
Its good to get opinions but you have to reasearch, run the specs and consider cost yourself. Only then should you choose what brand or type to buy.
How much did you guys pay for your Optimas? I have specs for them but do not yet have prices.
