Last year I picked up a new cranking battery for my ranger and went with an interstate flooded battery that “met” the requirements. After a season of low voltage issues, graphs shutting down at start up and constantly getting the low voltage alarm I went with an expensive optima 31 agm battery and have to say I should have done it last season and saves the money I spent on that interstate. All the issues I had with the last battery are gone. Soon as my everstarts burn out I’ll get two more optimas to run the Tm. Can’t believe the difference. So happy.
