it there a graph showing temp vs capacity . here in oregon day temps are 40-50s and night 30-40's is this why my range is 50% of GOM ?
Yes, all types of batteries are "cold-blooded" -- they slow down and perform worse when cold. There are lots of graphs of capacity loss vs. temperature.
But you have to find one for the particular type battery you have -- they are all different. What chemistry is it? What make/model (not who sold it, but who actually made the cells)?
