You might consider AGM batteries, they are pretty much maintenance free, no water to add. Penn Manufacturing makes the Deka brand which we have used for several years, I will never go back to lead/acid batteries. The AGM's charge quicker, hold the charge better. I just clean the terminals annually. They are not as expensive as the ones you mention, I believe.
Skip why are AGM's better? I heard because you cannot add water to them they won't last as long simply because the water/ electrolyte does evaporate in the long run.
Also does AGM's last longer?
Thank you, Mike
AGM are sealed (they do vent in extreme overcharging) so the hydrogen does not escape. There is recombination inside the battery, thus they do not need water added.
