If fishing or boating are your hobbies, you have obviously used or heard about a trolling motor that is affixed to boats. These motors are mainly used to provide additional propulsion in water. Alongside the main engine unit of small boats meant for such activities, trolling motors increase speed and maneuverability. Using a trolling motor, you can speed up your boat or guide it through tricky corners easily. Trolling motors are mainly of two types:

  • Hand operated – which are used to allow greater maneuverability
  • Foot operated – which are used to increase speed as and when required.

Logically speaking, all motors need to have a power supply from which it harnesses operating power. For trolling motors, this power source is a trolling motor battery. These batteries are specifically designed for medium power output, enough to power an auxiliary motor. The best trolling motor battery provides you just enough juice to keep your boat running in case of main engine failure as well. You can always switch on a trolling motor battery in case you want to save engine fuel, which is quite a cost effective option.

    Types of Trolling Motor Batteries

    A trolling motor battery basically works as a secondary power option that you use when you need extra power. It also extends the active life of your main engine by providing it with rest and decreasing fuel usage. All this goes on to help you save money on maintaining as well as operating your boat. Trolling motor batteries can be of many kinds and made with different technologies. There are two distinctly demarcated types of 12-volt (typically) batteries which can be used with trolling motors: AGM (Sealed Lead Acid) and Lead Acid Wet-Cell batteries. The explanations of these types of trolling motor batteries are as follows:

    Lead Acid Wet-Cell

    These batteries arefrequently found in trolling motors. These are also the most affordable options for budget buyers. These can effectively handle the regular draining or re-charging associated with the usage of trolling motors. Usually, these units will last you between one to two and a half years, at best. These batteriesare usually priced at less than $100 and are of quite good quality. There is a downside to this kind of batteries. It is that they occasionally require maintenance measures like topping off accumulated water. These are also quite prone to damage from vibration and acid spillage. This uncertainty makes them a secondary choice for buyers.

    Absorbed Glass Mat (AGM) Batteries

    The second kind is AGM Batteries, where AGM stands for Absorbed Glass Mat. AGM refers to a sealing technology that is incorporated for security and safe usage. These units are completely sealed while manufacturing, making them leak proof. These batteries generally have afar better backup and longer active life than wet-cellbatteries. While a customarywet-cell battery lastsaround two years, an AGM deep-cycle battery will typically last a user approximately four years. AGM batteries are the best trolling motor batteryfor improved performance and durability. They also come withthe added benefit of being completely maintenance free for their lifetime.

    Care and Maintenance Guide

    Since trolling motor batteries are used regularly, they will need maintenance from time to time. Trolling motors might face all kinds of rough weather because you can never be sure it will be all clear skies when you are out on water. Also, trolling motor batteries face a lot of direct exposure to water, which has electrical risks associated with it. It is important that you check and take proper care of the battery at regular intervals. Some of the basic standing instructions for trolling motor battery usage and care are as follows:

    • Do not mix battery types in a single circuit, or old ones with new ones. You will be risking a short circuit if you do.
    • Charge and discharge your batteries at regular intervals, even when they are not being used. Batteries that remain unused lose their potential through trickle discharges. This consequently reduces longevity of the battery unit.
    • In case of wet cell batteries, do check the fluid levels and refill as and when required. This helps the battery work at its maximum potential for a long time.
    • Check the battery terminals and clean the connector points regularly. If needed, use a solution of 1:2 baking soda in water to clean corroded metal.

    It is very important that you charge wet cell batteries in a place that is well ventilated place. This should be done so that no gas accumulates in its vicinity when it is being charged. Also, you should take care not to introduce any kind of fire or electrical sparks near a battery. That means no smoking or lighting up flares near an active battery in a confined space. Also, wet cell batteries should be kept out of reach of children or toddlers. If disturbed or toppled, a battery might leak fluid and gases which can be deadly when inhaled or brought in physical contact.
