Worrying about your battery or engine failing is the last thing to come to your mind while you’re in your boat. To ensure that you enjoy a safe and thrilling ride, use only a top-quality battery for your trolling motor.
Things to Consider When Buying a Trolling Motor Battery
You may face some difficulties when choosing the ideal trolling motor battery to buy. Although they’re all batteries, yet they’re different in some aspects. For this reason, you should do some research before buying to avoid regrets. To help ease your work, here are some of the things you should consider.
The wet-cell is the cheapest trolling motor battery available on the market. It uses an electrolyte to energize the cells. They can withstand frequent charging, discharging, and even overcharging. Thus, they’ve become the perfect alternative power source for cars and trolling motors.
The major issue to worry in this battery is the need for frequent maintenance. If you’ve been using a wet-cell battery in your car, you know what I’m talking about. So, you’ll need to add some quantity of distilled water to the liquid acid to keep it in good condition. Besides adding water, you’ll need to test the concentration of the acid with a hydrometer.
Since wet-cell batteries are not sealed, the sulfuric acid could leak. This will result in corrosion further decay of the cells. Any of these will dull the performance of the battery.
Your boat will likely venture into some rocky areas in the water and the resulting impact may cause leakage or permanent damage to the battery. Thus, the casing should be able to withstand the shocks. Also, your battery compartment should have enough ventilation to ward off hydrogen gas which they release.
Most anglers may prefer AGM (Absorbed Glass Mat) batteries to the wet-cell battery because they neither leak nor emit hydrogen gas. Since they’re sealed, you can mount them in any position. They’re mostly compact making them perfect for use in lightweight water vessels.
Also, AGM batteries will charge to full capacity within a short time. After a complete charge, it’ll take a long time to discharge, unlike a wet-cell. They’re lightweight, yet can store more power per area than a wet-cells. Thus, they’re the perfect trolling battery for small kayaks and boats.
Another advantage of the AGM batteries is that you can charge and discharge them without the need to maintain. Besides, they can withstand vibrations and bad weather.
It is important to use a smart charger with an AGM battery to avoid overcharging. Also, it is damaging to expose it to extreme heat. You may have to look beyond the initial cost of buying an AGM battery and focus on its long term benefits.
The Lithium-ion battery is the latest among other trolling motor battery types. Yet, they’re becoming more popular among anglers and hobbyist. This is because of their many benefits. The most outstanding feature of a lithium-ion battery is weight. This is because they’re lighter than both AGM and wet-cell batteries. Although they’re more expensive, yet they give the best performance.
Many manufacturers of electronic gadgets like smartphones and laptops rely on lithium-ion batteries. The reason is that they’re fast to charge and very slow to discharge. The Lithium-ion battery is more popular among sport anglers. This is because they charge fast, meaning you’ll spend less time waiting for its recovery. Also, being a lightweight trolling motor battery, your kayak will be light, fast, and easy to maneuver.
The only drawback with lithium-ion batteries is their tendency to catch fire when overheating. To avoid this, keep them away from direct heat sources.
2. Dual Purpose Batteries vs. Deep Cycle Batteries
You can either use a dual purpose or deep cycle battery to power your trolling motor. The design of these batteries allows them to discharge gradually until all the power is gone. A starting battery works differently in the sense that it’ll release a great percentage of its power only to trigger the engine to start. So, instead of a starting battery, you’ll need a dual purpose or deep cycle battery for your trolling motors.
Dual-purpose batteries can crank engines and power trolling motors too. So, dual-purpose batteries are used for both deep cycling and starting. If you desire to power your boat’s motors with a single battery, then dual-purpose battery is perfect.
Deep cycle batteries will discharge more of its power gradually over time. When used in trolling motors, deep cycle batteries tend to last longer than dual-purpose batteries. If you need a battery that’ll power only your trolling motor, then deep cycle battery is for you.
A deep cycle battery is designed to withstand all vibrations and shocks from the boat. Also, they’re not easily affected by heat. This makes them the right choice for kayaking in the sun.
3. Ampere hours (Ah)
The energy rating for deep cycle batteries is Ampere hours. This is defined as the total charge in the battery when one ampere of current is discharged for an hour. This unit is a measurement of the capacity of the battery. It gives a clue to the quantity of energy that the battery can store.
Some of the smallest deep cycle batteries have 25 to 50Ah while larger batteries can be as high as100Ah. Yet, there is no ideal ampere-hour rating for a trolling motor battery. You’ll buy a battery that’ll match your boat’s energy needs and fishing style.
So, if the Ah value is high, then the battery can power the motor and other appliances a bit longer. Also, if your vessel is large, then you’ll need a battery with a higher Ah rating. Besides, this value will drop with continuous usage of the battery. So, try checking the Ah rating before paying for the product.
4. Cold Cranking Amps (CCA)
It’s important to know the CCA of the battery when buying the best marine battery for your trolling motor. Cold Cranking Amps gives the quantity of current that leaves the battery within the first 30 seconds. If you’re buying a starter battery, then you’ll need to know its CCA. This will help you to know the initial large amount of power the starter battery can release.
While the CCA is only associated with a starter battery, the reserve capacity is for the trolling motor battery. The reserve capacity is given by the time it takes a battery to supply its energy before it runs out. You’ll only need the CCA if you’re getting a battery that will start your equipment and still run it.
5. Cycle life
This rating is mostly between 2 to 4 years. But you’ll rarely see it in the product specification. If the manufacturer doesn’t state the cycle life, you’ll need to read the product’s review to get the information.
6. Vibration Resistance and Durability
Before you decide on the trolling motor battery to buy, you need to know its vibration resistance. This factor is very important in the lifespan of the battery. This is because your battery will experience shocks when kayaking across choppy areas of the water. The ability of your battery to withstand this impact will determine its durability.
Looking at the weight is very important when shopping for your ideal trolling motor battery. The battery’s weight shouldn’t exceed your boat’s weight limit. Most trolling motor batteries weigh between 20 to 60 pounds. The best batteries for kayak trolling motor should weigh about 30pounds or less.
8. Design and construction
The type of battery will determine its design and construction. For example, all AGM batteries are sealed. Although wet-cells contain liquid acids like AGM’s, they’re not completely air tight. Some of the best-rated trolling motor batteries come with thick bodies that insulate them. This feature helps to extend the life of the battery and prevent the need for its early replacement.
One of the reasons you’ll prefer AGM batteries is their zero need for maintenance. Now, you’ll invest the money for buying distilled water regularly in other things. Also, AGM batteries are leak-proof making them easy to position or carry.
Some battery types are more convenient in terms of handling, installation, and maintenance. Reading real customer reviews of the product will inform you of its convenience.
Most batteries will only start the motor but won’t power other electrical equipment. So, the versatility of the battery is given by its number of applications in and outside the boat. Besides, your batteries should be used to power a motorcycle, wheelchair, alarm systems and much more.
