Decided to go ahead to replace my expensive odyssey battery with a standard flooded type. (an expensive lesson!) It looks like the 40R has the highest reserve capacity, among the batteries that will fit into the space behind the driver seat. That includes the 41, 42, 48 and 91. Ironically, the 40R is also the 2nd smallest one at 10.9 inches long, the 42 is 9.6 inches.

Hate to have to replace my expensive solenoid I've bought from Go Westy, but don't think it will fit into the box with the battery?  So, think I will go ahead in purchase a sure power 1315. I remember quite a while ago somebody posted a link where you could get them for fairly cheap.  Any suggestions as to a good place to purchase them today? I think they cost as much as the battery, if not more.
