Todd, I asked Surrette about their lead calcium batteries this morning, right after reading your post. Here's their reply:
I'm afraid our flooded calcium line is not yet available. Product testing went very well but at this time our present high demand for our other product lines has prevented us from moving forward on this new product line. At this time there is no estimated production date for a flooded calcium line. Bummer.

Surrette makes these too and they use next to no water and have a much longer warrantied life.

This was also at a time when battery manufacturers were just discovering solar so maybe battery designs have changed.
