What type of battery should be use for a trolling motor –introduction and size?

Jan 22, 2022   Pageview:307

Your electric motor system's battery is a crucial component. Always choose a top-of-the-line deep cycle marine battery. Deep cycle marine batteries, unlike vehicle batteries, are mean to be depleted and then recharged. Note: Always recharge your battery after usage to extend its life. The absence of proper charging is the leading cause of trolling motor battery failure. A 12-volt deep cycle marine battery with at least a 110-amp hour rating, often a group 27 size battery, always recommended. You will get more run time if the amp hour rating is higher. If an amp hour rating is not available, choose a deep cycle battery with a minimum reserve capacity of 180 minutes. A trolling motor is one of those difficult to live without, but getting the most out of it is difficult. Spring is on its way, and it is time to get your boat ready for fishing. The battery, including its initial selection, maintenance, and charging, is critical to the performance of a trolling engine. A trolling engine requires a deep cycle battery to maintain a constant high power demand. Ideally, you should match your battery discharge to the trolling motor's power usage. Trolling motor batteries are manufacture exclusively. They are design to provide electricity over a longer period. For fishing trips, using a trolling motor battery to prevent battery failure is critical to maintaining the required amount of power. Car batteries, on the other hand, they are used to start the car or give enough power to start the vehicle's engine. Starting the engine with marine batteries is critical, as is providing enough power to support the motor and other boat-connected gadgets.

Can you use a regular battery for a trolling motor?

You can, but you should not. It may be more cost effective to use an existing battery than purchase a new deep cycle battery for occasional use, but if it will be sitting around unused, it is better to have a deep cycle battery. Regular automotive batteries are not "Deep Cycle" batteries, therefore thus cannot be completely discharged or left unused for long periods. Deep cycle batteries made to be depleting almost completely and then gently recharged. Car batteries are design to handle a high-amp load for a short period before being recharge. The difference is in the construction of the battery plates, as deep cycle battery plates are engineer to avoid corrosion from deep discharge. Furthermore, fast allow current to flow in a circuit, a car battery features thin lead plates that are close together and have a lot of surface area. In the world of batteries, it is a sprinter. Sure, it can run an endurance race, but it has not built for it. It does not enjoy it, and will have a limited lifespan if forced to do so. A marine battery, on the other hand, is design to release a moderate quantity of energy over a lengthy period and features thicker lead plates with less surface area. In the world of batteries, it is comparable to a middle distance or endurance athlete. It is never the best sprinter, but it can go the distance time after time. Your trolling motor can be power by a 12-volt automobile battery. However, you will only be able to do so for a fraction of the time that a dedicated deep cycle battery could, and your car battery's lifespan will be drastically reduce if you chose to deep-cycle it for trolling.

What size battery do I need for a trolling motor?

You will be able to get away with a group size 24M battery with roughly 70-80AH for minimal trolling. If you use your trolling motor frequently, a group 27 M with roughly, 80-90AH would generally suffice. A group size 31M battery with roughly 90-110AH is ideal for a lot of trolling. The higher the amp hour (AH) value, the longer the battery will last. The group size is simply a reference to the battery's actual measurements.

Is a deep cycle battery better for trolling motor?

Deep cycle batteries are not like regular batteries. They made to give your trolling motor consistent energy over a longer period. When combined with a trolling motor, they will deliver outstanding results. It depends on your needs; with a dual-purpose motor, you can have the best of both worlds. Deep cycle batteries are a good option if you want a battery that will last longer in your trolling motor. Deep cycle batteries made to supply your trolling motor with consistent energy and power over a longer period. Navigation aids, fish finders, running lights, radios, and trolling motors are some of the main loads that these batteries are used to power. Depending on your needs, a dual-purpose motor can provide the best of both worlds, but if you want a battery that will last longer in your trolling motor, deep cycle batteries should be consider. RELiON offers a wide range of deep cycle devices, including lithium and AGM batteries.


The correct charge has the greatest impact on the battery life of your trolling motor. For best performance, use a trickle loader to maintain maximum charging throughout the season. Charge your trolling motor battery on a regular basis, save it in a clean container, and store it in a dry, temperature-controlled location for a more responsible use. If you are concerned about vibration or jostling damaging the cells, consider investing in a more durable AGM battery or testing lead-acid wet cell batteries with a hydrometer or voltmeter. When trolling, drain as much as possible by keeping your speed low and constant and remaining still in choppy condition. By understanding energy usage needs, taking proper care of your battery, and practicing prudence while on the water, you will have consistent, trouble-free performance from your trolling motor season after season. Suggestions that are beneficial when it comes to choosing a trolling motor battery, it all comes down to how you want to use it. The following are some useful hints: After each use, recharge the batteries. To keep batteries from depleting, keep them in a cold, dark place. Make cautious to inspect for corrosion before using. Batteries should never be mix. Corrosion can severely diminish the trolling motor's power output. If you notice rust on the battery's surface, you can quickly clean it using a solution of water and baking soda.
