A few weeks ago I emailed optima with that very question - their reply was to use the yellow top, the red top is strictly for starting, winching is considered abusive to the battey. The yellow top is a deep cycle battery. I emailed them at firstname.lastname@example.orgI'm looking to replace my battery. Which Optima battery is recommended for a starting/winching. Would the red top get me by?? I also have an electric fan on my Chevy V8 that seems to drain my current battery. Any help would be greatly appreciated!
I run the Red Top dual post. I buy them new at Costco for $100.00
