[RE-wrenches] intermittent battery problem; ...Battery Sulfation

I digress but... the best battery for grid tie with backup is not lead antimony, but lead calcuum. Surrette makes these too and they use next to no water and have a much longer warrantied life.

 No doubt these would be great in some standby grid connected system but I no longer use them in off grid.  This was also at a time when battery manufacturers were just discovering solar so maybe battery designs have changed.
