Thank you for replying. As you probably have gleaned I am a cranky retired lead acid (flooded) design engineer, whose company performed independent cycle life and troubleshooting investigations for several OEM's.
In your chart above am I correct in assuming a 50% DOD. OEM's had nothing but problems with group 31 cycling exercises due to significant issues with acid starvation. Thusly I do not see many non VRB group 31 batteries in the cyclable market place. Love to know if your 31 competition was a Rolls / Surrette :)
Finally your product enjoys a deservedly high reputation amongst the desert Baja Mil, racers because the spiral cell configuration seems to withstand high number G-force shocks with significant advantage over traditional VRB construction.
