Thanks to Rich and Joe for your comments.
It sounds like the Dynasty UPS 12-475 might
be a great EV battery. The weight is impressive
at 99 lbs since most Group 31 batteries including
Dynasty's 12-300 and the Optima weigh about
70 lbs or so.
This battery is promising enough for me seek more
information. I'm planning to replace the tired
T-105s in my Ranger sometime in 2002 and
12-475s might be the answer.
