Need a marine starting battery? We have the model that fits your boat. NAPA’s marine batteries are built to resist vibrations and deliver their power to ensure smooth start of your boat’s engine. Use our battery selector to confirm fitment or browse by application to find the perfect match and get the CAA you need.

Need power you can count on? Shop our deep cycle batteries. These batteries will never let you down and are perfect for powering accessories on your boat like your lights or radio, but can also power your golf cart, a wheelchair or any electrical vehicle that requires strong and long lasting power.


Marine batteries may be starting batteries, deep cycle batteries or dual-purpose batteries. The biggest difference between a starter battery and a cycle battery is the way they discharge their energy. Starter batteries are designed to discharge a large amount of energy on a short period of time. They are ideal for starting engines, such as a car or even a marine engine. In contrast, deep cycle batteries are designed to discharge a smaller amount of energy over a longer period of time. This kind of battery is ideal for all your boat’s accessories like navigation devices, radio, or lighting system. Often, deep cycle batteries spend almost their entire energy capacity and then can be recharged so they can start another cycle. We also use deep cycle batteries for small vehicles, such as electrical wheelchairs or golf cart. Depending on your leisure, you can buy a starting or deep cycle battery, or even buy both of them.


Deep cycle batteries consists of fewer but thicker plates than regular batteries. This characteristic allows the battery to provide continuous power output over long periods of time. They are designed to discharge a small amount of energy over a long period. Often, deep cycle batteries are compared to a marathon runner. Indeed, those kinds of batteries offer less speed than starting batteries, but much more endurance. Because they are designed to discharge a small amount of energy over a longer period, deep cycle batteries are often used to power small vehicles, such as electrical wheelchairs, golf carts, a trolling motor, etc. Depending on your form of transportation, get the right deep cycle batteries for better results!
