It's time for me to replace my batteries in my boat. Currently I have two Optima blue tops with 750CCA. They are still holding a charge but are 7-8 years old. Has anyone purchased Duracell AGM marine batteries from "Batteries + Bulbs"? Looking to stay away Optima's because of all the terrible reviews in this forum and elsewhere (due to manufacturing change) even though my experience has been positive with them over 16 years with them. My boat is a Trophy Pro 2352 with a 5.7L engine. Fish mostly saltwater in the sound & the ocean. Not a lot of electronics on board, typical Lowrance GPS/sonar but two Scotty downriggers that draw on the batteries quite a bit. Planning on getting dual purpose batteries again and would prefer to stay under $275 each.
