You love your boat. You take it out with family and friends, and it's the perfect getaway on the weekends or for longer trips. Eventually, the day to buy a new battery comes along. You go to the local boat store, and you're bombarded with battery options.
Most marine stores will have an entire aisle dedicated to batteries. It can be overwhelming. Unfortunately, you can't simply pick one and hope it works.
Here, we're going to discuss the different kinds of marine batteries, and how to choose the right one.
Types of Marine Batteries
Like we mentioned before, there are many batteries to choose from. But, we can break down battery types into three categories. Sometimes you will require more than one type of battery.
Once you know what category you fall into, you can determine what size battery you need.
Also known as cranking batteries, and just like the name, these batteries start the boat's engine. Somewhat similar to how a car battery works. Starting batteries put out a lot of power for short bursts to crank up the boat and get you moving.
Starting batteries cannot run electronics on the boat. If you try to use a starting battery to also run electronics, you will likely drain the battery and kill it.
Deep Cycle Battery
If your boat has electronics onboard, you'll likely have a deep cycle or running, battery along with a starting battery. These batteries keep everything running while you're offshore.
These batteries are rechargeable and can withstand battery depletion more than starting batteries. With each charge, they are back to full capacity, much like a cell phone.
Since these batteries keep your GPS, lights, or other electronics running, you'll want to have a battery with a running time at least twice of what size you think you'll need. It's better safe than stranded!
Many people are choosing dual-purpose, or hybrid, batteries now. These batteries act as both a starter and a deep cycle. Because this is a 2-in-1, you might sacrifice some power that you would get from two batteries. However, many small boats with minimal electronics to run use these dual-purpose batteries without issues.
Choosing the Right Marine Battery For Your Boat
Now that you know the kinds of batteries that exist, you can narrow down what you need. Always stick to the same kind of batteries your boat manual recommends. The manual will also tell you what size, or rating, your engine, and boat use. Always get at least the recommended rating.
Some tips for maintaining marine batteries:
Don‘t mix old and new batteries in the same bank. The old battery will drain the new one.
Keep away corrosion by using baking soda and water.
Use a battery monitor to check the output of your batteries regularly.
Discard old batteries in a safe, eco-friendly way. (Most marine stores will have a free drop off for old batteries.)
