The Benefits of a Deep Cycle Marine Battery

The next time you cruise back to shore from a day on the water, thank your boat battery. The battery is a link between your enjoyment and your safety. Without a solid battery, you’re liable to get stuck out on the water. 

That said, not all marine batteries are the same. Understanding the difference between a deep cycle battery vs regular battery is important, and it might be time for you to brush up on that knowledge. 

We’re going to take a look at the idea of a deep cycle marine battery today, giving you some insight into why you might want one. Let’s get started. 

What are Deep Cycle Batteries?

The “cycle” of a battery is its transition from charge to discharge. Most batteries will come with an expected number of cycles that they can go through, and that number indicates how long your battery will last.

The idea of the cycle is a little misleading, though. There are healthy cycles and unhealthy cycles, and each brand of battery is a little different. In most cases, there’s a little fine print that tells you what level your battery needs to reach before it gets discharged. 

For most units, a healthy discharge occurs a while before the battery is technically dead. Many units need to get recharged at around 40 or 50 percent. 

When you start to dip below that number, your battery starts to lose efficacy. In other words, the next time you use the battery it won’t do as well out on the water. So, it’s important that you look into that number before you start using the equipment that the battery is powering. 

Standard batteries are more temperamental when it comes to discharging percentages. A deep cycle battery doesn’t have the same need. 

Deep cycle batteries can get recharged after they’re pushed to well below 20 percent. They require less maintenance and they’ll last a lot longer than standard batteries.

Understanding The Deep Cycle Marine Battery?

The marine deep cycle battery is designed with thicker plates. There are also fewer plates, which allows the power to flow continuously with fewer interruptions for a longer period of time. 

The standard boat battery is referred to as a “cranking battery.” These batteries can’t be used heavily and recharged many times without starting to fail. The deep cycle battery can, and it’s great for running your electronics. 

The cranking battery ensures that your boat starts effectively, but it might not be able to accommodate all of the other technology on board. To be safe, it’s wise to have a deep cycle battery that produces enough power for everything you have on the boat.
