Boat Batteries

Marine batteries in their three uses: starter (short high-current burst to crank inboard or outboard engines), service or cabin (slow deep discharge powering radio, GPS, plotter, fridge, lights, windlass) and dual purpose (compromise for small boats with a single bank).

Marine batteries operate in permanent humidity, engine vibration, extreme angles and tilt at anchor: that's why we recommend sealed AGM or GEL — spill-proof and vibration-tolerant. For long autonomy, LiFePO4 lithium delivers 4x cycles and 100% usable capacity.
