So you’re confused with marine batteries and wondering which one to buy for your new boat. Choosing the right battery for your new boat can be challenging as you’ll be overwhelmed with the choices. There are so many different types of batteries, and each one has its own advantages and disadvantages. With different types of batteries on the market, including deep cycle battery and lithium deep cycle battery, it can be quite tricky to choose the right one, especially if you’ve ever purchased a marine battery before. So, how to choose? Don’t fret; the following tips will help you choose the best battery for your boat:-

Different Types of Marine Batteries

Cranking Batteries

A boat’s engine requires abundant power. The battery’s lead plates should contain a larger surface area to deliver quick power than the batteries that lack a larger plate surface. This’s why cranking batteries are designed with several lead plates that are thin so that the alternator will regenerate the battery quickly while the boat runs.

If you have a boat with state-of-the-art sensors, pumps, and computer equipment, ...
... you’ll need more powerful batteries to run your boat. The last thing you want to do is skimp on starting power. Check your boat’s manual for the MCA/CA rating before buying the battery. Never purchase a battery with a rating that’s less than the recommended range. Instead, choose a battery with the same or high ratings for better performance of your boat.

Choose a Deep Cycle Battery with a High RC Number

If your battery has trolling motors and powerful electrical accessories, you’ll need to go for deep cycle batteries. Deep cycle batteries with a reverse capacity will let you know how long the battery will carry the load before it begins to conk out. Batteries with high reverse capacity numbers have the ability to power your accessories in the boat for a long period. Remember, a deep cycle battery with high RC can double or even triple the reverse capacity of a cranking battery, making it endure hundreds of discharge and recharge cycles.

Dual-Purpose Batteries

While deep cycle and cranking batteries are best and can power the boat for a long time, they’re not always suitable for most boats. Some smaller boats only have enough room for one boat battery due to weight limitations. Most dual-purpose batteries won’t last the number of deep discharge and recharge cycles. So, they’re suitable for small boats.
