I am thinking about buying a blue top marine deep cycle for a extra battery for the Truck Camper and also use it in the boat when I am not camping. Anyone have good luck with this battery?
This has more amp/hrs than the blue top and they work very well. If you use two batts, I would use two of equal type/size/age for peak performance. Deep cycle batteries should be charged and discharged at the same rate.
I have one starting Optima and two deep cycle optima batteries in my Bass boat, for the last 4 years. No problems, they are lighter in weight, no water to add, seem to hold the charge longer.
I have had three and they all went bad, two were covered under warranted. Another thing to look at they only have 55amphrs. For about the same price you can get an AGM with more amphrs.
Old Days, when battery shopping don't forget to comparison that battery you are looking in Optima to any brand name in a AGM style battery. They get a lot of money for that name brand just because they did a great job selling back in the day.
