Marine Battery FAQs
What’s the difference between starting, deep cycle, and dual purpose batteries?
Starting batteries give high short bursts of energy to turn over your engine. Deep Cycle batteries provide steady power for longer periods. Dual-purpose batteries do both — for boats that need a single, versatile option.
Do I need a second battery for my boat?
If you’re running accessories like fridges, lights or electronics when the engine’s off, you’ll likely need a Deep Cycle house battery in addition to your Starter battery.
How do I choose the right marine battery?
Use our Battery Finder or speak to your local Marshall dealer. We’ll help you match your battery to your boat size, engine type, and electrical loads.
