What To Look For When Examining The Best Trolling Motor Battery


Amperage Hour Rating


The amperage hour rating is the total amount of current a product can deliver theoretically. For instance, a 100 amp hour model should be able to deliver 1 amp for 100 hours or 100 amps for one hour. This means that if a motor is drawing 5 amps of current, the charge should sustain it for about 20 hours. In the same way, if the electric motor was running at a very high speed and drawing 40 amps, the 100 amp hour battery will only sustain it for 2.5 hours. Generally, the higher the amp hours, the longer it should hold a charge, if the current drawn is the same. This is one of the number one things when looking for good marine batteries.

Cell Type


Two types of cells are commonly used to make deep cycle batteries: lead acid wet cells and absorbed glass mat. (AGM) dry cells. The wet cell batteries are currently the most affordable. However, these batteries require frequent maintenance and they last for about 18 to 24 months. They are also prone to vibration and spillage of the electrolyte. On the other hand, AGM deep cycle batteries can last for up to four years. These batteries are maintenance-free and can be protected from vibrations. However, they are quite expensive – they cost twice as much as the standard deep cycle battery.

Ability to Hold Charge


One of the distinct features of a good trolling motor battery is the ability to hold charge for a long period. Frequent charging will lead to a rise in your electricity bills and nullify all the savings you made when you bought the battery newly. The ability to hold charge is sometimes measured by number of charge cycles the battery can offer. The best batteries don’t get discharged while in storage, they can stay charged throughout the off-season and even retain their charge for up to 1 year.

Vibration Resistance


Trolling motors vibrate a lot while in use, unfortunately this causes vibration of the inside plates, which reduces their ability to retain their charge. That is why the best brands of trolling motor batteries are vibration resistant. Some high end batteries use a wound construction to minimize the damage due to internal vibration. Similarly, premium quality batteries have a spill proof design that prevents the product from leaking out its contents. So you can mount your batteries in almost any position within the boat.



Some top line brands provide special accessories such as battery power centers and digital charge readers, which aid the transport and storage of the battery. The transportation case provides safer access to the terminals while the built in meter enables you to know how soon you will need to recharge it.


Why You Should Only Use A Marine Battery For A Trolling Motor

A boat that uses a motor is in many ways like any other type of vehicle powered by internal combustion. This means that a boat motor operates using the basic principles of a cycle of rapidly firing controlled explosions of fuel which then move the pistons inside of the engine block and transmit the same motion to the drive shaft.

In cars and other land vehicles, this movement is transmitted to the wheels which then turn and provide motion. In boats, the movement is transferred to the boat’s propeller, which spins in the water and provides the same effect – the craft moves forward. Because all of these vehicles operate on the same principle, they also come with the general set of parts which makes up their engine components.

You may know of many individuals who own and operate boats, and are tempted to think that a part which looks the same and operates on 12 volts can come from any source. After all, they might wonder why should anyone buy specialized maritime parts and elements for a boat operation if any other can do the job as well at a cheaper price.

This type of reasoning is especially prominent in the case of trolling motor boat batteries which are regularly replaced with car batteries by the novice owners. However, this approach is exceedingly problematic and can lead to a range of issues which would be otherwise completely avoidable. Here are the key reasons why all boat owners should always purchase batteries which are specifically designed to be used for trolling motors.

The Size of Plates

When it comes to lead acid 12 volt batteries there are two types. The first ones are starter batteries, which are used in cars, while the other ones are called deep cycle batteries and they usually become employed in solar power systems.

Car batteries have more lead plates, but these are thinner. Deep cycle models have a smaller number of plates but are a lot thicker and heavier. Marine batteries, on the other hand, is classified as a hybrid solution, which places in between these two. They are similar to regular car batteries in size but they come with a lot thicker plates.

The Build of Boat Batteries

Each marine battery is built in a way that makes them a lot sturdier than regular car batteries. This is done to prevent damage from shaking and vibration, which are a regular occurrence on any boat. Additionally, most of them are not meant to ever discharge more than half of their capacity in order to protect the longevity of its plates.

Maritime batteries that operate using the deep cycle system are recommended only for boats that have a large array of electrical devices, like GPS and fish finders, navigation lights, radios and rolling motors. These tend to siphon power constantly during the use of the boat. In this case, the deep cycle models, which can discharge about 75 percent of their charge in continuity, are usually recommended as an option.

But, in any case, a car battery, which is designed for the rapid initial discharge of current that is needed to start turning the engine, simply has neither the built nor the capacity for a boat-type use. When it comes to voltage, a marine battery will be able to provide a deeper discharge process, but also more frequent discharges than any product designed for a car.

Because of all of these reasons, it is clear that utilizing a car battery in a boat is not a good option. Instead, using specialized maritime batteries can provide the boat owners with more power and a substantially longer working life of the same product.



Things To Consider When Purchasing A New Trolling Motor

If you have replaced your trolling motor battery and your trolling motor is still not working properly it may be time to by a new one. Below is a brief overview of what to look for when in the market for a new device.


It is important to determine the amount of thrust you would like your motor to have. It is usually measured in pounds and it is the main determinant of the motor’s power. Normally, the heavier and larger a boat is, the more thrust it requires for satisfactory performance. You should not skimp on thrust power. It is very frustrating to be in a spot where the fish are biting good, but your trolling motor will not hold you in the proper position.

Boat weight

The rule of many anglers on the water is that for every 100 pounds of boat weight, you require a minimum of 2 pounds of thrust. It is advisable that in the boat weight calculation, the worst case scenario is considered. This normally occurs when the boat is full of people, gear and has a full tank of fuel.

Fishing conditions and style

Individuals who go fishing on lakes that have little or no current (generally smooth) require trolling motors with minimum thrust. On the other hand, people who fish in water bodies with strong currents (rough conditions) need trolling motors with significant thrust.

Additionally, if fishing for long periods is your poison then considering a powerful motor should be on top of your priority list. This implies that you will need an engine with a higher voltage and more than a single battery. Electric motors for fishing are available in 36, 24 and 12 volts. A 24-volt requires two batteries to run while a 36-volt requires three batteries. The higher voltage types use lower amps to provide higher thrust and consequently higher power.

There are charts that contain thrust recommendations for all boat types. They clearly highlight common thrust ranges for common boats depending on their weight and application.

Location of motor

Trolling motors that most people use can often be put into two categories. The transom mount and the bow mount. The transom mount type is installed at the back of the boat while the bow mount type is installed at the front of the boat.

Boats that have trolling mounted out front in the bow mounted offer greater control and maneuverability. This promotes easier and more efficient fishing. Increase in maneuverability directly translates to a stronger pull in water.

Transom mounts are more suitable for smaller trolling boats.

Additional features to consider when looking for this equipment is devices with built in advance technology, trolling motors are coming to market with new features everyday. Some of these include the following:

Built in gauges – Some models are designed with battery gauges that are incorporated into the housing. These help to check the amount of power that is left in a battery.

Digital displays – Exorbitant models readily come fitted with digital screens together with readouts of depth and speed.

Self-directional motors with GPS  – These permit complete hand and foot free operation . It follows spot lock location or depth contours of shorelines without any guidance. It is even effective in windy conditions.




Buying a durable trolling motor battery that can hold charge and deliver adequate power to the electric motor is a wise investment. Although some lower end batteries may provide service when you are on a budget, it is better to buy a product that will last longer and give you peace of mind.
