I just got 2 new Optima D34M batteries and I went to hook them up to my ProMariner ProSport 12 on-board charger. Then I got to thinking do I need to do anything different when hooking these Optima D34M batteries up compared to my old everstarts that I had?
There is a label on the ProSport that says Lead Acid and Gel Selectable and that is what has me wondering….
Thanks in advance!
