Marine Charger

There are a couple of important things to keep in mind when choosing the right marine charger. First, check to see whether your marine battery’s voltage is 12, 24 or 36 volts. Look for a charger with the same voltage setting. Another thing to consider is the kind of battery you have. Boat batteries are either flooded, gel, AGM or lithium. Be sure that the type of charger you choose works for the specific battery that you’re using.

Additionally, the needs of your marine battery charger depend upon where you'll be using it. If you'll be charging your battery in damp environments, it's important to have a shock-resistant and waterproof battery charger. A vibration resistant charger is also helpful if you'll be carrying it in your car or boat, as the extra strength will help prolong your charger life and functionality.

Choosing a New Boat Battery

Maintaining a proper charge is key to your battery’s health. If you have a vehicle that you store over the winter or just an old car that you don’t drive very often, a charger will help you keep it charged up and ready to go. Here are a few of the different battery chargers available.

Deep Cycle Batteries

A heavy charge and discharge cycle makes these batteries perfect for strong,
sustained power. Choose a deep cycle battery when you need to operate a live well pump, trolling motor or depth finder.

Shop Deep Cycle

Starting Batteries

These batteries provide strong and fast power. When you need to power an
inboard/outboard motor or operate accessories like radios and lights, starting batteries are the best choice.

Dual Purpose Batteries

When you're looking for power that does a bit of everything, dual purpose batteries deliver the strength you need. The burst of fast power starts your engine, while the
cycling capacities offer the sustained and reliable drive to operate your accessories.
