The Ultimate Guide to Marine Cranking Batteries

Marine cranking batteries are designed for use on boats, and they offer some unique features that make them perfect for this purpose. This buying guide will help you learn about the different types of marine cranking batteries available to consumers, as well as what to look for when buying one. By understanding these factors before you buy a battery, you'll be able to find the best option at an affordable price point.

What Are Marine Cranking Batteries?

Marine cranking batteries are commonly known as starting or car batteries. They have a high cold-cranking amps (CCA) rating, which is the number of amps that can be continuously drawn from it for 30 seconds at 0 Fahrenheit/degree without dropping below its minimum operating voltage level.

CCA is an important spec to look for when purchasing a marine cranking battery because it determines how well the battery will start your engine in cold weather.

What Size Battery Do I Need?

The size of your battery is determined by the amount of power it can provide. You need to select a battery that has a CCA rating that is equal to or greater than the sum of all the electrical loads that will be connected to it.

For example, if you have a boat with a 60-amp alternator and you plan to install an extra refrigerator, then you need a battery with a CCA rating of at least 120 (60 + 60).

Marine Cranking Battery Types

There are two types of marine cranking batteries: lead-acid and lithium-ion.

Lead-acid batteries are the most common type and they come in both flooded and sealed versions. Flooded lead-acid batteries like Car Audio Batteries require periodic watering, while sealed lead-acid batteries do not.

Lithium-ion marine cranking batteries are becoming more popular because they have a higher power-to-weight ratio and a longer service life than lead-acid batteries. They do not require any type of maintenance, which makes them ideal for boats that spend most of their time in the water.

Things To Consider While Purchasing Marine Cranking Batteries

There are still many more factors that you should consider before deciding on a set for your boat or personal watercraft. If you're interested in learning more, you can continue reading below.

Affordability 

The marine cranking battery is the most common type of boat and personal watercraft battery because they are inexpensive to purchase and maintain. You can check the Battery NKC which are also affordable battery options. 

Multiple Vessels 

A single marine cranking battery will likely not be enough for smaller boats or vessels with less electrical demand. You'll need at least one set to provide power for starting the engine and running essential electronics.

Battery Life

Marine cranking batteries will typically only keep their full power output for a few hours, so you'll want to consider this when planning your day on the water. But you can check Portable Marine Battery Chargers to charge them quickly anywhere.

Conclusion

In conclusion, the marine cranking battery is a very important part of your boat. It can be dangerous not to have one in good condition, and if you do end up buying the right kind for your needs it will last a long time. Remember all these things when looking at batteries so that you make sure you buy the best possible option for yourself.
