Battery Tender

Battery Tender (by Deltran) changed the way boaters maintain their batteries with their "set-and-forget" smart charging technology. Unlike traditional trickle chargers that can overcharge and damage cells, Battery Tender units feature a 4-step charging program that automatically switches to a storage/float mode once the battery is full. Their marine-grade, waterproof chargers are ideal for maintaining starting and house batteries during the off-season or between weekend trips. Shop Freeport Marine Supply for Battery Tender to ensure your batteries are always charged, healthy, and ready for your next launch.
