A cranking battery plays a crucial role in a boat’s electrical system. Its primary function is to provide the necessary power to start the engine and get the boat moving. For fishing enthusiasts, having a dependable cranking battery can significantly impact their experience on the water. This article will cover the basics of bass boat cranking batteries, the importance of selecting the right one, and a list of the best ones.

What is a Bass Boat Cranking Battery?

A bass boat cranking battery is a special kind of battery used to power up the engine of a bass boat with quick and powerful bursts of energy. It is different from a deep cycle battery, which is made to provide a consistent flow of power over a longer duration. A cranking battery is designed to deliver short bursts of energy for starting the engine.

The Importance of Choosing the Right Cranking Battery:

Selecting the appropriate cranking battery for your bass boat is important for several reasons:

  1. Using a battery that lacks the necessary power or specifications for your boat can cause damage to your engine or fail to provide sufficient power to start it.
  2. An inadequately chosen battery can malfunction at critical moments, leaving you stranded in the water.
  3. The right cranking battery can enhance your boat’s performance and provide additional power to onboard electronic devices.

Therefore, making an informed decision when selecting a cranking battery for your bass boat is crucial to ensure its smooth and reliable functioning.

Factors to Consider When Choosing a Cranking Battery:

Before deciding which cranking battery to purchase, there are several key factors to consider.

Battery Type:

There are two primary types of cranking batteries: lead-acid batteries and absorbed glass mat (AGM) batteries. While lead-acid batteries are generally less expensive, they require more maintenance than their AGM counterparts. On the other hand, AGM batteries may be more expensive upfront. Still, they typically require less maintenance in the long run.

Reserve Capacity:

When we talk about the reserve capacity of a battery, it means the amount of time for which a fully charged battery can power a particular load. If the reserve capacity is high, then the battery will last for a longer time. In simple terms, reserve capacity determines how long a battery can keep running after it is fully charged.

Cold Cranking Amps:

Cold Cranking Amps (CCA) measure the battery’s ability when starting your engine in cold weather. The higher the CCA rating, the better the battery will work in chilly temperatures. Choosing a battery with a high CCA rating is essential if you live in an area with cold winters or frequently experience low temperatures. This ensures your car starts easily, even on the coldest mornings.

Maintenance Requirements:

Each type of battery has its own set of maintenance needs. Some batteries need to be checked and maintained regularly, while others do not require any maintenance. When selecting a battery, it’s essential to consider how much time and energy you are prepared to invest in maintaining it.


The cost of a cranking battery can differ greatly based on the brand, type, and features it offers. Considering your budget and determining which features are necessary for your specific requirements is crucial.

How to Properly Maintain Your Cranking Battery

To ensure the longevity and optimal performance of your cranking battery, it’s important to follow these maintenance tips:

  • Regularly clean the battery terminals and cables to prevent corrosion.
  • Check the water levels in lead-acid batteries and top up with distilled water as needed.
  • Keep the battery fully charged to prevent sulfation and extend its lifespan.
  • Store the battery in a cool, dry place when not in use.

How long does a cranking battery last?

The lifespan of a cranking battery depends on various factors, such as the brand, type, and maintenance. A well-maintained cranking battery can last approximately 3-5 years.

How do I determine the size of the cranking battery required for my boat?

To determine the right size and type of cranking battery for your boat, refer to the boat’s manual or seek advice from a professional.

Can I charge my cranking battery while connected to my boat?

It’s possible to charge your cranking battery. At the same time, it’s still connected to your boat. Still, it’s recommended to disconnect the battery to avoid any electrical hazards and ensure a proper charge.

Can I use a car battery as a cranking battery for my boat?

While a car battery may work temporarily, it’s not recommended as it’s not intended for marine use. It may not provide the power or durability required for your boat’s needs.
