I keep a small fishing boat at one of the marinas near Dubai Marina and the deep cycle I've been using is struggling to hold a charge after just one season. The guys at the dock said most people either upgrade to a proper 200AH or end up replacing cheap ones every year. I started looking around and found a mention of Superior Battery Specialist Dubai Marina that apparently handles bigger batteries for marine and off grid use, not just car swaps. Has anyone here dealt with them for something that isn't a standard sedan? I'm mostly curious if they come to the boat or if I'd need to drag the battery out myself which is a pain given how heavy these things are. Also wondering if there's a noticeable difference between maintenance free and the ones where you top up distilled water because I don't mind checking levels if it lasts longer. Just tired of losing power halfway through a day out.
