I run CAT batteries on everything at work. Cat has not been able to tell me who makes them but they are reasonably priced for me and they have lasted well. My other go to that I know are really good batteries are Deka. I have a pair of group 31 Deka batteries in my blazer that I got as good used ones out of a semi back in like 2012 and they were in my blazer at least 4 yrs with me only hooking them up once a month to run it up to temp then unhooking them. Then I drove it a few yrs and now the last year and a half it has sat and they are ready to go any time I decide to go fire it up.
