Battery failure in the middle of a trip can be the worst thing that could happen to a boater. To avoid any such misadventures, you should think about buying a quality deep cycle battery that is powerful and lasts longer than a normal battery.
In this article, we will cover everything you need to know about a Best deep cycle battery trolling motor battery. So, let’s get right into it.
Buyer’s guide to choosing your next trolling motor battery
Although batteries for trolling motors are made by very few companies. But if you are new to this, choosing the right battery even from these handful batteries, would be a tough decision.
Don’t worry, our team has researched well for you. Before going into our battery recommendations, we would like to educate you about different factors that determine the quality of a battery.
Batteries that are used in the trolling motor are generally of two types
Lead-acid wet cell batteries
These types of batteries are quite affordable, but they require a lot of care. After every few days, the user is required to manually check the water level of the battery, which is a tiring process. Moreover, they don’t last for long.
Absorbed glass mat (AGM) batteries
Although AGM batteries are expensive, they make life easier for you. You are not required to add water into these batteries because its ingenious catalytic cap makes water by itself. They don’t require any maintenance but need to be replaced once they wear out.
A deep cycle battery is the most reliable option for a trolling motor. They generate power that can last longer than most common batteries. These batteries ensure reliability and are safer to use.
Usage of a battery
Batteries are usually required to achieve two different usages.
This refers to the use of a battery as an alternate power source and not the main source. If you need the battery only for emergencies, you can use cheap batteries that don’t allow repetitive discharge.
It refers to the use of the battery as the main source in trolling motors. For this type of usage, you need expensive batteries that allow repetitive charge and discharge.
The weight of a battery matters a lot. A heavily weighted battery makes the installation /removal process very tiring. Although some anglers don’t care much about the weight and don’t mind wrestling with it. But we would advise you to always check the weight of the battery before buying it. A light-weighted battery will prove to be very convenient for most people.
Amp Hour Rating
Amp hour rating is the measure of time for a battery’s life provided with a given amperage. Amp-hour rating is generally an important factor for all types of batteries. But when we specifically talk about batteries for trolling motors, its importance multiplies.
Trolling motors are usually used for long trips and anglers don’t have the exact calculation of time in mind. You can’t take risk battery failure during the trip. So, in order to avoid such issues, you need to go for a battery with a greater amp hour rating.
Cold Cranking Amps (CCA)
Cold-cranking amps is another important factor that has many applications. Look for a battery with at least one CCA for every cubic inch of engine displacement. CCA is directly proportional to the starting power of a battery.
Battery’s reserve capacity
For trolling motor batteries, the reserve capacity is a very critical factor. It is the measure of time that a charged battery can sustain provided with constant high load. If your trolling motor constantly requires greater amperes, a greater reserve capacity will prove to be very handy.
The importance of this factor is dependent on the user type. If someone likes to go fishing every now and then, this factor will not have much of an impact as there will be time to completely charge the battery.
On the contrary, if someone likes to go fishing frequently and is a fan of multiple trips in a single day. There will not be much time to charge the battery. So, opting for one with less charging time will be a smart choice.
Maintenance & Safety
Maintaining a battery demands a constant effort that could be very tiring. We recommend choosing a battery that does not demand time and effort.
Following the instructions religiously while installing or removing a battery is crucial. Not following precautions can cause safety hazards.
