Best marine battery for electric trolling motor

Trolling motor batteries are specifically designed batteries for use with boat trolling motors. Their main function is to provide trolling boats with more electricity as they slowly navigate different fishing zones. Trolling motor batteries are sometimes confused with starting batteries used for ignition. Marine batteries require that you first start the engine, and once the motor has enough power to sustain itself and the devices connected to then this battery type can pick up. Here is an overview of the top factors to consider and our top picks.

Types of marine batteries

Several types of marine batteries are designed to power the boat’s motor. The most common ones include:

Deep Cycle Batteries/ Dual Purpose Batteries

They are the best marine battery for electric trolling motor with consistent energy supply. Deep cycle batteries are unique, unlike other products found in the same industry. They work efficiently to keep the engine running for a lasting timeframe.

Deep cycle batteries are unique because their stability in energy provision is consistent. So, you are guaranteed an exceptional fishing experience while trolling for motor in the waters.

It’s worth noting that a dual-purpose battery is quite powerful and can easily start the boat’s engine and still turn it over. Besides that, it can be used to supply your trolling motor with consistent energy efficiently.

You can choose either battery, but if you want to experience the best of each world, then choose a dual-purpose battery. Meanwhile, if durability and a lasting life cycle are important to you, a deep cycle battery will cater to your needs.

Lithium Marine Batteries

They are superior battery alternatives since they have better profiles than AGM and lead-acid wet cell batteries. Lithium batteries stand out because they have deep cycles and longer life spans. Besides that, they consistently maintain power without the need for maintenance.

These batteries have faster charge times, which helps ensure that you can have an amazing marine time anytime. Besides, they offer a high-quality energy supply even though they are lightweight in nature. I consider purchasing a lithium battery, then you are guaranteed of:

  • Safety due to the battery’s non-hazardous design
  • Temperature resistance
  • Long-lasting shelf life
  • Constant power supply

Absorbed Glass Mat (AGM) and Lead Wet Cell

When choosing the best marine motor for electric trolling motor, AGM is usually more popular than Lead Wet Cell batteries. However, the latter remains one of the most used batteries to troll motors.

Lead acid wet cell stands out since it’s affordable and offers value for money. Besides that, it has design features that make it possible to handle every day trolling activities. But some people might easily avoid it due to the shorter life cycle that often lasts between 2 and 3 years. Additionally, this battery type needs some maintenance.

AGM batteries, unlike lead-acid batteries, are fully sealed. Their seal-proof nature makes them quite expensive. However, they don’t need any maintenance, so they offer value for money.

So, what’s the best marine battery for trolling motor? The truth is that it all depends on your preferences, needs, and budgets. Choose a battery that you think suits you, including your marine life.

Factors to consider when selecting a trolling motor battery

There are many components that make choosing the best marine battery for trolling motor quite challenging. However, knowing these factors beforehand can help you make the best choice, especially when choosing a battery that suits your needs and meets your budget. The most important factors to consider when buying a trolling motor vehicle include:

Battery Type

As stated above, there are multiple battery types, but the primary ones include the 12V deep cycle and AGM batteries. However, lithium batteries are also becoming quickly popular in the recent past due to:

  • Lightweight nature: they are extremely light than the traditional batteries, i.e., almost 70% light
  • 100% discharge is important in ensuring that you have a constant energy supply regardless of the battery’s discharge level.
  • Consistent power: many activities happen while fishing, including sudden speed fluctuations, cranking torque, and consistency in supply. Well, lithium batteries now offer all these.

Amperage Power

For understanding, you can equate a battery’s amperage-hour rating to that of a gas tank. Take note that a battery’s amp-hour is crucial in determining the longevity of use. So, the higher the amp-hour time, the longer the battery will last.

That’s why a battery with 150-Ah will last longer than its counterpart with 100-Ah. When choosing a battery for marine trolling motor, ensure that it has at least 100 Ah. This is important in ensuring that you stay in water for as long as possible. If you are going for longer expeditions, get a higher AH battery.

Note: when choosing the Amp-Hour battery rating, ensure that you also consider the group size rating and voltage. Of course, the standard voltage in this scenario consists of 12V. But if you have a battery of group size 24, then the amp-hour rating should be between 70-85. Meanwhile, a Group Size 31 will need an amp-hour rating to deliver the best results.

Voltage

The standard voltage, especially for deep cycle batteries, is 12 volts. However, it’s advisable that you always check your power system before heading outdoors to determine if you should power up or not.

Note: when it comes to voltage, some subsystems may need 24 V or sometimes 36V. But for trolling motorboats, 12 V is the best.
