I know people disagree, but I
NEVER use sealed batteries... I only use wet cell batteries. If people
want no maintenance, they should not have a "survival mode" system.
That level of unconsciousness is what usually creates the need for
"survival mode". If it is grid tie with battery backup consider the
flooded lead calcium cells. They only need watering every 5 years or so. my .02 Todd Peter Parrish wrote: --I am an infrequent (3/year) designer/installer of grid-tied battery back up systems. I really like the SunXtender battery line. We can get them for a good price (contact me off line) here in Los Angeles.With that, I cannot vouch for cycling them 1,200 times to 80% DoD. That seems a bit severe. I have a graph of #/discharges vs. DoD for thee batteries. I will try to dig it up and make it available. - Peter Peter T.
