What Type Of Battery Is Best For Trolling Motor. Over the course of the last several decades, trolling motors have seen a meteoric rise in demand owing to the fact that they are comparatively affordable, silent, and lightweight.
It doesn’t matter whether you use them for trolling, for maintaining your boat in a certain position with a GPS anchor, or for fine adjusting boat control by utilizing a foot pedal while fishing from your boat; trolling motors have completely changed the landscape of recreational fishing.
When choosing a battery for your trolling motor, there are a few important considerations to keep in mind, including the following: The budget, the amperage hour rating, and the kind of battery all need to be considered.
For trolling motor, what sort of battery do you recommend I use?
You need a battery that can handle deep cycling, like a marine battery.
What are the distinctive characteristics of the various Deep Cycle Battery types?
Batteries with a sealed absorbed glass mat (AGM) and lead acid wet cells
Will the battery from my vehicle be able to power my trolling motor?
No, we do not advocate using automobile batteries since they might damage your engine.
Which of these is the least expensive choice?
The most cost-effective alternative for your trolling motor is to go with lead acid wet cell batteries. On Amazon, this 35ah battery, this 55ah battery, this 70ah battery, or this 100ah battery is one that we often suggest to customers.
Deep Cycle versus Starter Batteries
The majority of people are acquainted with huge and heavy automotive batteries; however, there are really two different kinds of batteries that suit this description: starter batteries and deep cycle batteries. Batteries known as deep-cycle batteries are characterized by their capacity to discharge a relatively low quantity of current over an extended period of time (ex. running a trolling motor for hours).
Starter batteries, on the other hand, are intended to discharge a significant quantity of electricity in a very little period of time (ex. starting a car engine). Starter batteries are not intended to have their charge repeatedly drained to a level below 50 percent, only to then have that charge brought back up again and again.
When put through this kind of usage, starting batteries won’t have a very long lifespan. If you use a starting battery with a trolling motor on a regular basis, you might end up damaging both the battery and the motor.
It is advised to use either Lead Acid Wet-Cell or AGM batteries, both of which are deep-cycle batteries with a voltage of 12 volts, for an electric trolling motor.
Wet Cell vs. AGM: Lead Acid
Wet-Cell: Lead Acid AGM: Activated Glycol Monohydrate Wet-Cell batteries are by far the most prevalent and cost-effective alternative for trolling motors. Their lifespan is typically between two and three years.
They often cost less than one hundred dollars, but they are sensitive to vibrations and subject to spillage; in addition, they do need some care.
The term “wet-cell” describes a kind of battery in which the individual cells or plates are “flooded” or completely covered by an electrolyte solution that is a mixture of water and sulfuric acid. If the battery is recharged an excessive number of times, the water level will decrease;
in order to maintain the appropriate water level, it is important to sometimes top up the battery with distilled water. Damage to the battery and a reduction in the amount of time it may be used effectively can occur if the electrolyte level falls low enough to reveal the plates and cells of the battery.
AGM batteries are more recent than their Wet-Cell counterparts; in addition to being entirely sealed, they are also able to hold their charge for a longer period of time and have a longer lifetime overall. Because AGM batteries are sealed, they do not need any kind of maintenance; yet, their cost is more than that of identical Wet-Cell units due to the fact that they have a life expectancy of up to four years.
Absorbed Glass Mat is the abbreviation for this kind of battery, which is also known as a Valve-Regulated Lead-Acid Battery (VRLA) or a Sealed Lead-Acid Battery (SLA). The electrolytes, in contrast to the case with wet-cell units, are contained in glass mats rather than fluid.
These glass mats are constructed from extremely fine glass fibers that are braided together to form a mat in order to increase the surface area. This increase in surface area is sufficient to keep electrolytes on the cells throughout the life of the battery, which results in the battery being lighter, more resistant to spilling, and less likely to be damaged by vibration.
It is the real quantity of charge that the battery is able to hold, and the Amp Hour Rating is what decides how long you will be able to run the motor for. If you want your trolling motor to operate for a longer period of time, you will need additional amp hours.
A more precise definition of capacity would be the amount of charge in a battery that would enable one ampere of current to flow continuously for one hour, as well as the amount of energy that could be stored by the battery itself. A battery with 80 AH capacity, for instance, will be able to provide 100 amp hours of electricity to a trolling motor and will last far longer than a battery with 50 AH capacity.
With some basic algebra, you should be able to figure out how long a motor will keep running on a given battery. When operating at maximum speed and attached to a battery with a capacity of 50 AH, a trolling motor will draw 52 amps from the battery.
Which will result in the battery lasting around 0.96 hours. (52 amps drawn from a 50 AH battery Equals 0.96 hours of run time) On our page devoted to calculating the run time of trolling motors, you may find more information.
The application is the single most important factor to consider when determining the appropriate battery amperage hour rating. A battery with a rating of 100 to 120 ampere-hours would be required in order to power a Newport Vessels 55-pound thrust motor continuously for two hours at maximum speed.
On the other hand, if you drive for two hours at moderate speeds with pauses in between, you’ll only need a battery with a rating of between 50 and 100 AH. Using the calculation up above, you should be able to get a rough estimate of the battery that will be the most suitable for your requirements.
- Never combine batteries of different ages or kinds.
- After each usage, the battery should be recharged right away.
- Maintain the charge on the battery.
- Regularly checking the fluid level of lead acid wet-cell batteries and topping them up with water as needed is recommended maintenance for these types of batteries.
- Inspect the terminal connections of the motor for any indications of corrosion, which may cause an increase in the motor’s resistance and a decrease in its power output.
- Baking soda and toothpaste may be used to scrub away any corrosion.
- To prevent the battery from being entirely depleted, keep it stored in a cool, dark area while also attached to a trickle charger.
- In order to get the most out of your trolling motor battery, we recommend using this in conjunction with our Smart Battery Box.
