- Battery Selection
Marine batteries provide 2 essential services: Start your motor, power your electronics and lights, both services are vital for your safety and enjoyment on the water. We offer a wide selection of marine batteries in a variety of sizes.
There are 3 types of marine batteries:
- Starting Batteries are built to crank your engine
- Deep Cycle Batteries are designed to run the electronics for long periods of time
- Dual-Purpose can provide both services
- CCA (Cold Cranking Amps) the number of amps a battery can discharge for 30 seconds at 0°F while maintaining its voltage above 7.2 volts
- MCA (Marine Cranking Amps) the number of amps a battery can discharge for 30 seconds at 32°F while maintaining its voltage above 7.2 volts
Chemical makeup of marine batteries:
- Flooded: the least expensive, and most popular marine battery. Available in all 3 types, may require maintenance.
- Gel: a mid-grade sealed, low maintenance battery, available in all 3 types
- AGM (Absorbed Glass Mat):
the most expensive, maintenance free battery, available in all three types
Battery Storage Capacity
We recommend your marine battery is capable of storing 4 times the average daily consumption. If your boat consumes 150Ah per day on average, consider purchasing a marine battery with 480Ah of storage capacity. This will avoid deep discharges, and reduce recharging times. Learn how to measure your boats daily battery consumption.
