Choosing the right marine battery can be a bit challenging. There are so many types out there that it can feel like you’re diving into the deep end. We’re here to help you find the best one for your needs.
Before you start battery shopping, take a look at the various types of marine batteries below that you can get from lithium battery manufacturers. This will help you identify which one is right for you.
Common Marine Battery Types
There are three basic types of marine batteries: dual-purpose, deep cycle and starter. Each of these batteries has a specific job to perform.
1. Starter Battery
A starter battery is used to start your boat’s motor. It’s also called a crank battery, and it produces a big amount of power in a short time. However, this type of battery won’t keep your boat running.
2. Deep Cycle Battery
Unlike starter batteries, deep cycle batteries have thick plates that allow them to provide consistent power. They’re ideal for powering various equipment such as your trolling motor, GPS and lights.
3. Dual Purpose Marine Batteries
The term dual-purpose refers to the type of battery that you can use for both your starter and deep cycle applications. However, like some “jacks of all trades,” dual-purpose batteries are not always capable of providing the power that you need. Most commonly, these types of batteries only last for a few cycles.
If you have a trolling motor, you’ll need both a deep cycle battery and a starter battery. It’s usually a good idea to purchase dual-purpose batteries to cut down on space and money. However, this method is only a good idea if you’re planning on using a lithium chemistry battery.
The chemistry of marine batteries is what makes them different from other types. In this article, we’ll talk about the most common types of marine batteries.
Types of Marine Batteries by Chemistry
All marine batteries are made with different materials. Some of the materials used in the production of these batteries are superior to others. Before you buy the remote control for your AC unit, you probably thought that the batteries at the dollar store were the cheapest option. However, what if they suddenly go out? You could get stranded in the heat without an AC supply.
The cost of batteries is always higher than the quality of their materials. However, if you’re planning on using a better quality marine battery, it’s usually a better investment than a cheap one.
1. Lead-Acid Batteries
One of the oldest types of batteries used in boats is lead-acid. This type of battery has a combination of acid and lead plates. It’s commonly used for powering various equipment such as your trolling motor. Compared to other types of batteries, lead-acid batteries are very heavy and bulky. They can weigh around 80 pounds each, and depending on the power that you need, you might need two or three batteries.
2. Ionic Lithium Batteries
Unlike lead-acid, lithium iron phosphate batteries are made with a different kind of chemistry. This combination eliminates the issues that plague lead-acid batteries. Compared to other types of batteries, lithium marine batteries are lighter, longer-lasting and charge faster.
Unlike lead-acid, lithium marine batteries are not prone to leaking. They also don’t require regular maintenance, which is great for both boaters and those who use their equipment for fishing and camping. With a lithium marine battery, you can expect to get the same output at 100% charged as with a low charge.
Unlike lead-acid batteries, lithium marine batteries can be discharged past 50% without damaging them. Also, with Bluetooth capabilities, you can monitor the status of your battery on your smartphone. These are dual-purpose batteries, which means they can be used to power various equipment such as your lights and fish finder.
Although lithium batteries are the most expensive type of marine battery, they’re also the best long-term investment. In the long run, you’ll get a better return on your money by considering how long these batteries will last. If you’re planning on using your boat for a long time, lithium is the best choice. There are various types of batteries available, and you can find one that’s right for you.
