Choosing the Right Marine Battery for Your Needs

Not all marine batteries are created equal. Before you buy, consider how you'll use your boat. Deep cycle batteries are ideal for powering electronics, trolling motors, and onboard accessories over long periods. Starting batteries, on the other hand, are built to deliver a strong burst of energy to get your engine running. If you need both, a dual-purpose battery provides a convenient all-in-one solution to handle both tasks.
