If your starting point is unsure, continue to read about cranking batteries and which one you should get for your bass boat. What is the best cranking battery for bass boat?

The purchase of a boat can be an outstanding purchase. After all, it can be hard to keep the properties, styling, and prices involved in your purchase when you walk around the boat show and get excited about all the latest models of new bass boats. 

When you take your time and use this guide to prepare your next bass boat, you will have a good head on your shoulders, including what to look for in your future purchase. Then you can take a deep breath and think about whether this new high-tech template is what you need. Let’s start with the basics first.

What Are Bass Boats?

The bass boats are specifically designed for bass fishing, with sleek, low-profile water disrupting for better fishing. Typically these boats can carry two to three passengers or fishers, but some larger models can accommodate four or five people. The bass boats are between 16 and 26 feet in length and have a variety of options between them.

For all the benefits of these boats, the lack of passenger capacity, the lack of crossover options for other fishing excursions, and the relatively high cost to them in comparison to other boat types turn some people off. However, these boats are worth every penny for the true bass enthusiast.

Bass Boat Types

Different types of bass boats for sale include cruising boats and high-performance models for the severe angler. Large and small models are available with the option of fiberglass or aluminum hulls. Anglers can also choose bass boats, usually an outboard engine or trolling engine, based on their engine or motor type.

Be careful to remember that traditional bass boats are not all-purpose boats. They can occasionally be used to fish for other types of animals living in the same water as bass. These include freshwater fish in similar areas where you’d look for bass, but they aren’t very versatile as far as where you can catch and where you can fish.

Of course, people buy these boats for bass fishing specifically, so that it makes sense to customize these boats for that purpose. There are dozens of other boat styles available for other fishing needs. Mini bass models for the solitary angler are available with one passenger seat and room for you and your fish.

What Is A Cranking Battery?

A cranking battery enables a naval ship to start by sending the engine power when the ignition switch is switched on. This is why these batteries are also known as starting batteries. Short and strong energy explosions must be sent from the battery to start an engine.

The more flat surface in the battery, the easier it is to provide the necessary power to that battery. This is exactly why cranking batteries have a large number of small plates; they increase their surface area and make the start of a ship as smooth and reliable as possible.

The same elements that make a starting battery perfect for cranking a motor also make it less than ideal for continuous discharge or “cyclic” application. This is why deep marine cycle batteries are another necessity for boaters.

More Information

Marine batteries can include starters, dual-use batteries, or batteries with a deep cycle. They are often hybrid of start- and deep-cycle batteries with plastic sponge plates, which are louder and louder than battery plates but not as large as real deep-cycle battery plates.

You can hardly tell what you are getting in a marine battery, and the only way to know is to open it. The terms “marine” and “deep cycle” are often used together or interchangeably, which adds to the confusion. For example, the “deep cycle marine battery” battery can be built in the same way as the “deep cycle.” RV battery.

A starter battery is fine for inboard or outboard marine motor but goes on a deep cycle battery if you need a trolling motor.

What Is A Deep Marine Battery?

Deep cycle batteries have thick plates and can be discharged up to 80 percent (deeply cycled). On the other hand, starting batteries produce short high current bursts to crank an engine, which means that only a small part of the capacity is often discharged. 

The main difference between true deep-cycle batteries and other batteries is that deep-cycle batteries contain solid plates, not a sponge. They are most commonly used in industrial backup and solar energy applications.

Once the engine of a boat is starting, it no longer needs the same quick and powerful energy bursts from a starting battery. The boat needs constant, reliable power to troll – including operational electronics such as sonar, GPS, and radios. This is where deep marine cycle batteries come in.

There are several design differences to a deep marine cycle or trolling battery. One key is a plate: it has less, thicker plates that allow the battery to produce continuous power over long periods of time. The deep cycle batteries can be drained completely and recharged many times.

Selecting The Best Cranking Battery For Bass Boat

Here are a few tips to help you choose the best cranking battery for bass boat.


Ampere hours is the capacity measurement unit for marine batteries. With a capacity of 100Ah, your battery will give your boat this value for an hour. The greater the capacity, the longer your fishing trips last, of course.

Reserve Capacity

The reserve capacity is expressed as the number of minutes required to discharge the battery at a continuous rate of 10,5V by 25A at 80 ° F. Better because it means that your battery will not die under load quickly. 

It is important to know that it’s a theoretical value, and the battery will probably draw less amperage at another temperature so that the battery will last longer.


Acid spilling is a major marine battery problem. You should consider getting a battery that is spill-resistant. Check the battery specs to see if it is spill-resistant or not.

Dimensions & Weight

On bass boats, size and weight can be a problem, especially because they are small in size. Normally, a larger battery has a greater capacity. It is better to get a battery with enough capacity to meet the requirements of your boat. 

You can check the battery’s specifications and check if they are compatible with the design of your boat. Portability is another consideration, especially if the battery needs to be moved.
