Buying a Trolling Motor Battery

 

trolling-motor-batteryThe most important consideration for the motor and the battery is determining the amount of thrust that is required. Thrust is the amount of power needed to move through the water and is measured as ‘pounds of thrust’. You need the right amount of power behind you to manoeuvre weather and waters. This article assumes that you have already assessed the size of the boat, amount of gear and the other weight conditions, and you at least have your eye on the best trolling motor for your needs.

Trolling motors come in three power systems: 12-volt, 24-volt, or 36-volt. Batteries are manufactured in 12 volts, so that would mean that you will need two batteries for a 24-volt power system and three for a 36-volt power system. You won’t pay much for a 12-volt motor, but a 24-volt or 36-volt motor will allow you to stay out on the water longer, as they have more power and lower amp draw. The best battery for a trolling motor is the battery that has the most power and longevity.

Trolling motor batteries are designed for prolonged, harsh use so this is another important consideration. The best brands will allow you to spend more time fishing than charging your battery. Sticker shock may cause you to want to back away from a high-end battery, but buying a less expensive battery may bring you back to the store more often. Factoring in thrust, weight and fishing conditions the right battery could well be worth the price when the right, quality battery can last up to six years.

Construction

Marine batteries have two purposes. One purpose is cranking the engine, and the other is powering the trolling motor and other electronics used on the boat. The cranking battery constructed with more numerous, thin plates is designed for the burst of energy needed to engage the starter and within a few seconds is recharged by the alternator. The cranking battery will overheat when used for the trolling motor.

The deep cycle batteries are designed to withstand the higher temperature requirement without adverse effect. The fewer, thicker plates provide better output for longer periods of time. The thinner plates in the cranking battery are also subject to damage from the vibration of the trolling motor. The thicker plates of the deep cycle battery are better able to withstand the vibrations. The vibrations can cause the internal plates to shift and damage the battery. You may find that the battery does not charge as it did before, or the battery is destroyed.

The best battery for trolling motors has a spill-proof design allowing the batteries to be configured in multiple ways. This becomes important when you need multiple battery hookups because of the size of your motor. A 24-volt motor will typically need to have a second trolling motor battery for consistent results.

Care and Maintenance

Even if you think you found the best battery for trolling motors, it will be a waste of money if the battery is not properly maintained.

  • As soon as you return to shore, it is important to recharge the battery. Not only will you be ready for the next time you go out, but it will protect the lifespan of the battery. Leaving the battery discharged will decrease longevity and performance.
  • Never mix battery types. If one battery is a wet cell battery, then the remaining batteries should be wet cell batteries also.
  • Never put an older battery with a new battery because the older battery will pull down the new battery.
  • A wet cell battery requires routine fluid level checks. Be sure to top off with distilled water to protect against chlorine damage from tap water.
  • Store batteries in a cool, dry place during the off season and hook the battery up to a trickle charge. If a trickle charge is not used, charge the battery at least once per month.
  • Ensure the tops of the batteries are clean and that the terminals are free from corrosion. If signs of corrosion are found, clean with a paste of baking soda and water or with a wire brush.
  • The 24-volt and 36-volt motor will require two or three batteries. This requires the batteries to be wired in series. In other words, the batteries need to be connected to each other. The positive cable from the motor should be connected to the positive terminal of the first battery. The next step is to connect the negative terminal of the first battery to the positive terminal of the second battery and so on.
