Dual Purpose Batteries vs Deep Cycle Batteries
Trolling motors need a steady and consistent source of electrical power, and that’s why you need to use either a deep cycle or a dual purpose battery. These two batteries have been designed to gradually discharge a considerable percentage of their power capacity for a long period of time. The dual purpose and the deep cycle batteries are different from a starting battery which has been designed to discharge a large amount of power at once to start the engine. This is why you can use a dual purpose battery to power your boat the whole time you’ll be on the water.
Dual purpose batteries have been designed to crank up engines and still provide a consistent source of power for 12v electrical devices like trolling motors. If you want only one battery for your boat, then a dual purpose battery is your best bet. As the name suggests, a dual purpose battery serves a dual purpose, and this is both starting the boat as well as to keep it in motion when deep cycling.
Deep cycle batteries have been designed to specifically discharge large amounts of power over a long, gradual period of time. Deep cycle batteries last longer as compared to dual-purpose batteries when they are being used with trolling motors.
If you want an all-round battery that can be used for starting your inboard or outboard motor and still power your motor, then the dual purpose battery is your best bet. If you need one specifically for your trolling motor, then your best bet is the deep cycle battery.
Best Trolling Motor Batteries
They look like any other, and they tend to do the same work; however, some batteries are better than others when it comes to their performance as well as other factors. You have a lot of options, but you are on the lookout for the best. Here are some of the best;

Wilderness Tarpon 100 is one of the best kayak trolling motor battery. It’s a 12v 35Ah battery with a little size and great power. This can run a 55lb kayak carrying 4 people for about 45-50 minutes without the charge running out.
This battery is smaller than other marine trolling batteries with its dimensions being 7.7 * 6.5 inches; it weighs a mere 23 lbs. This can fit in any compartment of your boat, but if your boat doesn’t have any, then you should get some.
How To Choose The Best Trolling Motor Battery
You need to consider a few things before you pick a good trolling motor battery. Some of the things you need to consider are;
Amp Hours (Ah)
Deep cycle batteries get rated in ampere-hours (Ah) which is a unit that measures the total amount of charge in a battery that allows one ampere of current to discharge for 1 hour period. This is to say the number of amp hours a battery is rate shows how much electricity the battery can store. Ampere-hour is one of the most important features you should look for when buying a deep cycle battery since it determines the number of hours a battery can power a trolling boat.
For dual-purpose batteries, this unit of measurement is not always available, which makes it difficult when calculating the amount of time the it can run a trolling vessel. All in all, small trolling motor batteries should have between 25 and 50 Ah while a larger deep cycle battery for trolling should go up to 100Ah.
There is however no perfect amount of ampere-hours that a trolling motor battery should have but the higher the Ah, the better for you because you’ll have longer hours in the waters.
The Power System
Most of these deep cycle batteries are in 12v which means you might need several to power a 24v trolling motors. Therefore, before you get any battery or batteries, it is essential to know your motor power system as well as it demands. Most boats are built with 12 volts system, but occasionally especially if it’s a larger boat, it needs either 24volts or 36volts to power it.
It is imperative to look at the weight of your batter although it is not as important unless it slows you down when on the waters. Most of the best trolling motor batteries weigh between 20 to 50 pounds; the lower the weight of the battery, the better it is. The weight of the battery depends on your weight capacity which means if your boat has like 500lbs free, you can definitely go for a 50lb trolling motor battery. Most people who use kayaks prefer to go with a trolling battery that weighs less than 30lbs.
Cold cranking amps (CCA)
Cold cranking amps or CCA as it is commonly known is the number of amps releases in the first 30 seconds of powering at 0°F. CCA is only important for starting batteries where large amounts of power need to be released for a short amount of time. The reserve capacity the length of time a battery can release electricity usually under 25 amps before it needs to be recharged.
The CCA unit is only useful when you are looking for a dual purpose trolling battery since the battery has two functions; starter motor and keeping it running during your fishing expeditions.
The cycle life
The lifespan of your battery is known as a cycle life. It is however not common to see companies advertising the cycle life of their batteries. Most trolling motor batteries cycle life is between 2-4 years. Since most companies don’t declare their batteries’ cycle life, your best bet is reading the product reviews; most customers give honest opinions so, you’ll get an idea on the cycle life of a particular brand.
|Trolling Motor Thurst (lbs)||Amps Drawn at Various Speeds||Approximate Run Times with 35AH (In Hours)||Approximate Run Times with 50AH (In Hours)||Approximate Run Times with 100AH (In Hours)|

Types of batteries
There are many trolling motor batteries in the market, and it can be quite confusing when choosing the one that fulfils your angling needs. Just because they are all batteries doesn’t mean they function the same way. Using low quality batteries can lower your trolling motor’s efficiency. If you are looking to have a smooth time in the waters, then you should do your research thoroughly;
Wet or flooded lead acid (FLA)
These are classified into three classifications. The first classification is the wet lead acid batteries commonly known as the flooded trolling batteries. They have a simple design, but they can live up to two years. They are manufactured easily and cheaply which also means they are easy to buy.
Less wet lead acid batteries are being produced to power trolling motor batteries; you should only buy these flooded trolling batteries only if you understand how to use and maintain them.
Absorbed glass mats (AGM)
This is the second classification of trolling motor batteries, and they are considered more high end. These batteries have been made to provide constant charge for a longer time. Amazingly, AGM batteries last longer per every use and they last longer as compared to the other trolling motor batteries. Their lifespan is twice as long as the wet cell batteries. It is because of this longer lifespan that they tend to be more expensive as compared to other batteries.
Off late, the absorbed glass mats are moving out, they are more common, and the prices are evening out. The absorbed glass mats are most recommended for average anglers because they are more efficient as compared to wet lead acid batteries and they are also easy to take care of. The only downside to them is that they are a little pricier.
Gel batteries just like the name suggests are filled with a fluid that looks like gel. The fluid is what powers the battery, and it also protects it. Gel batteries tend to be a little resistant to vibrations as well as discharging when the battery is idle. These batteries are however not common in the stores, but with a little research, you can find quite a number of them.
Gel batteries are not so common which means the market is not as huge; there are few of them that have been made for trolling motors. The AGM batteries are the most common.
In conclusion, the best trolling motor batteries are an important part of your kayak or a fishing boat. Never overlook these batteries because they can be a matter of life and death when you are out there in the waters. A trolling motor battery is what determines whether you will go back to the dry land in one piece or not; therefore, research extensively and make a sound decision before you buy one.
