Optima battery??..

I use optimas in most of my junk. There are specific charging instructions with a gel or agm battery. If you follow them, the batteries last a long, long time. If you buy an optima, look up optimatrays.com. Specific holders for optima batteries. They are priced fair and bad ***. My boss’ boat is 21 years old. It’s on its second set of optima blue tops.
