Tips for Optimizing the Life of Your 24V Trolling Battery

24V 100 Ah Lithium Battery - Tournament Lithium Marine Trolling BatteriesAvid anglers understand the importance of a reliable and consistent power source for their trolling motors. To make the most out of their fishing excursions, it is critical to select the best trolling battery for the boat. In this post, we will guide you through the process of choosing the best 24V trolling battery on the market, taking into consideration factors such as types of batteries, capacity, lifespan, and more. This ultimate guide will provide you with all the necessary information to make an informed decision, ensuring your time on the water is both enjoyable and successful.

  1. Types of Trolling Batteries:

There are three main types of trolling batteries available – lead-acid, absorbed glass mat (AGM), and lithium-ion. Lead-acid batteries are the most traditional and affordable option, but are known to have a shorter lifespan and require regular maintenance. AGM batteries are a more modern choice, are completely maintenance-free, and offer a longer battery life than lead-acid options; however, they are comparatively pricier. Lithium-ion batteries are the latest technology in trolling batteries, providing the longest lifespan and best performance overall. They are also the most expensive, but their advantages could outweigh the cost for some anglers.


  1. Battery capacity and runtime:

Battery capacity is expressed in amp-hours (Ah). A higher capacity battery will offer a longer runtime, allowing you to stay on the water for extended periods without needing to recharge or replace your battery. When selecting a 24V trolling battery, opt for one that will provide enough capacity to meet your demands during your typical fishing trip. Keep in mind that trolling motors have varying power requirements, so be sure to consider the motor size and hrs needed.


  1. Charging and maintenance:

Battery maintenance is essential for preserving the longevity of your battery. Regular maintenance can include checking electrolyte levels, cleaning terminals, and topping off in case of lead-acid batteries. However, AGM and lithium-ion batteries are both maintenance-free, requiring only a simple wipe-down now and then. Charging your trolling battery properly is also critical in ensuring its longevity. Keep in mind that some batteries may charge at different rates or require specific chargers, so make sure to follow the manufacturer’s recommendations. Using a compatible battery charger will help prevent overcharging and potential damage to your battery.


  1. Weight and size constraints:

The weight and size of the trolling battery are other significant factors to consider. Boats have specific weight limits and space constraints that must be taken into account when choosing a battery. In general, lithium-ion batteries are the lightest and most compact, followed by AGM and then lead-acid batteries. Factoring in these constraints can help you select a battery that not only meets your power needs but also fits comfortably within your boat’s designated space.


  1. Price:

Finally, the price of the battery should be considered, especially within the context of your budget. While lithium-ion batteries boast numerous advantages, they are substantially more expensive than AGM or lead-acid options. Take some time to assess the benefits of each battery type and weigh these against their cost. A high-quality trolling battery may be more expensive upfront, but the potential for a longer lifespan and improved performance could make the investment worthwhile in the long run.



In conclusion, choosing the best 24V trolling battery for your boat requires careful consideration of factors such as battery type, capacity, maintenance, size, and cost. By taking the time to assess your specific needs and understanding the advantages and disadvantages of each battery option, you can make a well-informed decision that will support your angling endeavors for years to come. With the right trolling battery, you can enjoy your time on the water knowing that your motor will be reliably powered throughout your journey.
