Boat Batteries 101

Boat Batteries for Sale OnlineThe battery is one of the most critical components of your boat. Not only does it keep your boat operating, it also powers your navigation lights, fish finder, pumps and much more. If it fails while you’re out on the water, you could be in big trouble.

As a result, you have to take a lot of considerations in mind when buying a new battery. Here’s a quick look at some of the different jobs a marine battery does and why the ODYSSEY® battery is your best choice.


If you fish, you know how important trolling your boat can be. For your boat to do this, it needs a deep cycle battery. Think about this type of battery like a marathon runner. When there’s no other charge available, your deep cycle battery will keep powering all electrical loads. Deep cycle batteries provide energy for extended periods, and the best designs can completely recover once you take your boat back to the marina.


You can’t start your boat without a battery, of course. A cranking battery provides the power needed for the motor to start. The problem with most starting batteries is that they can easily lose their charge. They need a strong alternator to get the charge back. Starting batteries also help power boat components such as bilge pumps, courtesy lights, etc. 

Dual Purpose

As the name implies, a dual purpose battery performs all functions of both deep cycle and starting batteries. Unlike conventional batteries, an Absorbed Glass Mat (AGM) dual-purpose battery can handle deep discharges. The plates inside this type of battery are typically larger and thicker, which gives it a great deal more power. Dual purpose batteries are very safe, very durable  and will perform for several hours at a time.

The EnerSys® ODYSSEY® Marine Dual Purpose battery is a true powerhouse with proprietary Thin Plate Pure Lead (TPPL) technology that makes it far superior to anything else you’ll find on the market.

Why is this important? Because the design of the ODYSSEY® Marine Dual Purpose battery allows it to hold many more plates than conventional lead acid models. Quite simply, more plates mean more power.
