Re: Start Battery Questions!

My local NAPA has learned to not ask.
Regarding your battery trays, you can always have the mobile welder-fabricator come out and make new ones on site, if your neighbors don't mind the ruckus.
Regarding battery weight, if there are three flavors of Group 31 batteries the heaviest is most likely the one with the most amp hour capacity. Regarding the Cold Cranking Amperage, they're all Starting Lighting and Ignition batteries. True deep cycle batteries are few and far between. Even Trojan, in the 8D size sells an AGM as 'deep cycle."
