Marine batteries have quirks that make them different from their power sources from their automotive counterparts. Marine batteries generally have much heavier plates and more substantial construction, allowing them to run longer and better resist vibrations. In addition, many of them are resistant to deep discharge, which is vital when they need to power a trolling motor or other electrical accessories that require much power. To optimize the boat's electrical system and make it more reliable is recommended to have multiple batteries.
Check out our large collection of marine batteries featuring the latest technical achievements, which come from Odyssey, Attwood, and other brands.
