I just got a Die hard from Sears. Inter State are also good batteries as well. they have 3 different DieHard line, GOld being the best. it was ballpark around $55.
I have had 3 Redtop Optimas in the last 3 years. for the $109 that they cost, i saw no significant worth. Thier only good point is that they are sealed and use Gel, not water. they do not leak, Period.
Each red top lasted me an avg of 1.5 years. I wont be buying another one soon.
