Marine Batteries for Sale

There are many kinds of marine batteries for sale. A lot of them are very inexpensive. The problem with that is if you go cheap, the battery might not perform when you need it the most. EnerSys® produces one of the most powerful and reliable batteries on the market – ODYSSEY® Marine Dual Purpose batteries. Losing power while on your boat won’t even be a distant concern, and that peace of mind will be much more important than saving a few bucks.

How We Pack so Much Power Into the ODYSSEY® Battery

Marine Batteries for SaleHow can we say that the ODYSSEY® Marine Dual Purpose battery is the most powerful available? The secret lies in our proprietary Thin Plate Pure Lead (TPPL) design. TPPL has been around for about five decades – it’s the way we use it that’s different.

Most types of batteries have lead plates. These plates supply the batteries with whatever amount of power they contain. But the plates in ODYSSEY® Marine Dual Purpose batteries are thinner than those in conventional lead acid models. As a result, we can fit more inside.

Without bogging you down in a lot of science, the bottom line is this – the more plates a battery has, the more powerful it will be. Our batteries also contain an Absorbed Glass Mat (AGM) design. So, they won’t just give your boat a considerable boost; they’ll also be virtually maintenance-free.


Another great feature of ODYSSEY® batteries is that they last a very long time. They can go through several discharging cycles and then go through several charging cycles without losing any strength. That’s one of the reasons why they can keep their power for hours and hours. ODYSSEY® batteries are also incredibly rugged. If you’re on choppy water, your battery will be able to withstand vibrations other batteries simply can’t.

Getting back to durability, one of the reasons why conventional lead acid batteries fail is they corrode after a certain amount of time. The typical battery has a grid structure inside, and this grid is immersed in sulfuric acid. After a while, this combination results in oxidization. That’s why you see corrosion at the connection points.

When corrosion develops, a battery finds it harder to handle current. The more corrosion occurs, the more stressful the environment. After a certain amount of time, the battery will no longer be able to supply current.

Because ODYSSEY® Marine Dual Purpose batteries have TPPL technology, they won’t undergo nearly the amount of corrosion seen in conventional lead acid batteries. Less corrosion means a longer lifespan. Our batteries produce two times the power and last three times as long as conventional lead acid batteries. ODYSSEY® Marine Dual Purpose batteries have a service life of as long as ten years, can perform in temperatures ranging from as low as -40°F (-40°C) to as high as 176°F (80°C) and can be stored for up to two years and still be effective.
