Secure and vented
Mount the battery in a proper battery box, strapped down so it cannot move in rough water or on the trailer, with ventilation as required.
Applications
Boats need strong cranking plus resistance to wave pounding and trailer vibration. Fit a sealed, vibration-resistant lead-acid battery, secured properly in a vented battery box.
On the water
Early starts at the ramp, a day on the water and a reliable start for the run home. Marine batteries have to handle vibration, spray and wave pounding.
Mount the battery in a proper battery box, strapped down so it cannot move in rough water or on the trailer, with ventilation as required.
Salt air is hard on connections. Keep terminals clean and protected, and check cables for corrosion before each season.
Boats can sit for weeks. Keep the battery charged during storage with a suitable smart charger so it is ready for the next trip.
