Mighty Max Battery ML55-12 SLA Trolling Motor Battery

Mighty Max Battery ML55-12 SLA Trolling Motor Battery

Mighty Max Battery 55-12 is a 12-volt battery designed specifically for trolling motors. This battery is ideal for smaller boats that require less power because it has a smaller capacity of 36 amp hours versus the more powerful 100 or 120 amp hour batteries available to purchase.

The ML55-12 has a lower cost, which is ideal for consumers who want to save money on their boat’s battery purchase and also factors into the higher environmental friendliness of using this battery. This is because a smaller capacity 12-volt battery uses less lead than a larger capacity 24-volt battery or other lead-acid batteries used for trolling motors. Also, the smaller capacity will last longer than larger capacity batteries when not in use because they will have less total storage time. A good example of this is the control circuit activates longer to drain the battery and that tends to reduce how often the battery is drained.

The ML55-12’s design allows it to fit easily into most trolling motors. The ML55-12 can be mounted flat against the motor or in a gravity position in a dual mounting system with an additional 12-volt trolling motor battery (the ML55-22). This is a unique feature of this particular battery. The ML55-22 is an identical battery to the ML55-12, but it has a higher capacity of 72 amp-hours. The ML55-22 is ideal for larger boats that require more power from their trolling motor, while the smaller capacity ML55-12 is ideal for smaller boats.

Pros:
This battery is cost-effective

This battery has a lower capacity than more powerful batteries

This battery is environmentally friendly and is made from lead-acid, which is not harmful to the environment when disposed of properly

This particular trolling motor battery has a dual mounting system for mounting with another trolling motor battery, which provides additional stability to the trolling motor

Cons:

While the ML55-12 can be mounted in a dual mounting system with another 12-volt trolling motor battery, it cannot be mounted in a dual.

The trolling motor brush used on the ML55-12 is not as durable as the brush available for use with other model trolling motor batteries.

Minn Kota 1820175 Trolling Motor Battery

Minn Kota 1820175 Trolling Motor Battery product review: A majority of trolling motors sold on the market today are powered by a 12-volt deep cycle battery. The Minn Kota 1820175 is an example of such a battery. However, there is some confusion as to which one might be best suited for the job.

This article will break down and compare both the pros and cons to help you make an informed decision about what type of battery suits your boat’s needs best.

Minn Kota 1820175 Trolling Motor Battery product review: The Minn Kota 1820175 is your typical trolling motor battery, but it offers some added features that drive me toward recommending it over others such as the Minn Kota 182019.

Pros:

Excellent timing lock feature allows for easier adjustment of start times for both trolling motors and standard engine motors. A simple 10-second button press allows the batteries to either be locked in their current settings or to be able to adjust them on the fly.

Includes a sealed heavy-duty dual-purpose protection circuit that completely isolates the battery from your boat while maintaining a high level of vibration and impact resistance.

Allows for the use of an optional “float switch” that allows the batteries to be shut down when they have reached a set level. This is ideal when your engine is started and then requires more time to warm up. The batteries will remain powered and locked in their settings until you unlock them with another 10-second pull of the simple button.

The Minn Kota 1820175, like most trolling motor batteries, has built-in connectors and dual-purpose terminals for both positive and negative connections. This makes installation simple. No need to find, purchase or install a separate set of terminals to connect the battery to your system.

Cons:

Like most similar trolling motor batteries, the Minn Kota 1820175 is a little pricey. This is not necessarily a con when you consider that it does have some very useful features you will not find with other trolling motor batteries. I think it is an investment worth making.

Summary:

If you are in the market for a really good trolling motor battery I suggest taking a closer look at the Minn Kota 1820175 or another product from this manufacturer. Both the Minn Kota 1820175 and the Minn Kota 182019 claim to be able to handle your trolling needs, regardless of your budget.

However, if you are on a tight budget, I would suggest trying a different brand. Brands such as Optima and Trojan are much less expensive than the Minn Kota batteries. You may find that they don’t have all of the useful features that make this battery so good.

In summary, the Minn Kota 1820175 is a quality trolling motor battery that is worth its premium prices.

How to Choose the Best Trolling Motor Battery Buyers Guide

Trolling motors are battery-powered engines used to move fishing vessels. These motors are installed on the stern of the boat and can be tilted from flat to vertical at any angle in between. The electric motor is a simple component that eliminates the need for a heavy outboard gasoline engine, suitable for slow-speed maneuvering in shallow waters. Trolling motors have come under criticism by environmental organizations like Greenpeace, who thoroughly dispute that it’s eco-friendly, while there has been little effort from manufacturers to address these worries or produce more efficient models of the device.

 

In this article, we will examine three major factors – durability, peak power draw, and maintenance – when choosing a trolling motor battery. These are important specifications to consider if one wishes to obtain a reliable motor that will perform well and last for many years. We will also discuss how to choose the right voltage for your boat and help you understand the importance of having adequate power output.

 

Overview

 

Durability is an important factor when choosing a trolling motor battery because they tend to be weak and won’t keep up with high speeds or high loads. These components can be frequently overworked, so it’s a good idea to find one that’s built for high peak power draws and maximum vibration resistance. This results in batteries that can withstand rough conditions and are durable enough to last through many fishing trips without failing before its time.

 

Peak Power Draw is a measurement of the maximum amount of current (amps) used by the trolling motor. It’s important to choose one with ample power output because if this number is too low it will only be able to sustain a slow speed and will eventually die during extended periods of use. A battery with too much draw can cause problems when trying to turn at high speeds because they tend to lack torque.

 

Maintenance is an important factor when choosing to troll motor batteries because they can be sensitive to over-discharge or faulty charging systems. One should always use a charger rated for the given battery, and keep an eye out for signs of failure or sulfur buildup, which requires immediate cleaning on the ports and terminals. Experts recommend never letting a battery sit in a discharged state for long periods of time.

 

Weight-On average, trolling motor batteries weigh between 6 and 12 pounds, so it’s important to find one with a minimalistic design if one wishes to haul it around easily. Smaller batteries with excellent weight distribution can be carried by the operator while bigger models will need to be lifted and hoisted by lifting tackle or other equipment.

 

Run Time is a measurement of the amount of time before the battery needs recharging. High run times are generally considered to be better because they generally last longer, although it’s important to consider power draw when making a decision. Smaller batteries are often used on smaller boats and require a shorter run time than bigger batteries which can often be used on larger ones.

 

Lifespan is the number of cycles (recharges) that a battery can survive before it starts deteriorating. Larger batteries tend to have longer lifespans than larger ones, but this doesn’t mean that one should completely ignore the size of the battery. It’s important to find one that will last a relatively long period of time without excessive deterioration or damage from misuse.

 

Vibration Resistance is an important feature to consider when selecting a trolling motor battery because it will determine how long the battery lasts. It’s recommended that batteries be placed in well-protected cases or individual mounts or carriers to avoid damage. If possible, avoid storing batteries indirectly exposed areas where they can be rattled and beaten by wind and waves.

 

Size is important because it determines how large the battery has to be and can greatly affect the weight of the boat. Larger boats will need larger batteries, which are often heavier, so it’s important to take this into consideration when choosing a trolling motor battery. Finding a balance between size and weight can help you find equipment that will last longer without becoming too burdensome on the operator.

 

Recharging is necessary for every trolling motor battery, and there are a few different ways to do this. There are battery chargers which can be plugged into an electrical outlet, solar panels which can be installed on the boat to directly recharge the battery, or portable rechargers that can be brought with you wherever you go. It’s important to choose one that will easily fit your budget and work best in your setting.

 

Electric trolling motors function by using an electric generator to power a propeller assembly of multiple blades. These motors create thrust by using electricity stored in batteries to spin the propeller. This method is often used when fishing in shallow waters with slow-moving boats and is also popular as a form of entertainment when waterskiing or tubing behind a boat.

 

These motors have individual control panels that can be used to rotate the propeller at different speeds while allowing different amounts of thrust to be generated. They can be tilted up or down in order to control the position of the propeller assembly and steer the boat accordingly. Recent models have been solar-powered, which eliminates the need for onboard power storage. This allows them to be much lighter and easier to maneuver than traditional trolling motor batteries.

 

Step-Up/Down Converters

 

Step-up converters convert low voltage (12V) to high voltage (120V) and step-down converters are used to convert high voltage (120V) to low voltage (12V). These inverters are necessary for power-supply applications where AC current is not available. It’s a good idea to keep an extra converter on hand, as most solar panels come with one that will need replacing if it gets damaged. If the converter is damaged it can be replaced with the same type or opposite type. A single step up or down converter can also be used in two opposite ways such as a 12 volt down step upconverter or a 220 volt up step down converter.

Best Trolling Motor Battery Types

If you are looking for the best trolling motor battery that can handle rugged terrain and extreme conditions, a trolling motor battery is a type for you. There are several different types of these batteries available, but it is important to know what type is right for your needs. This article will go through some of the different trolling motor battery types including:

Marine Trolling Motor Battery- A deep cycle marine battery has heavy-duty plates for better performance in tough conditions and temperatures.
The Deep Cycle Trolling Motor Battery- A deep cycle battery has strong plates that can be recharged after draining completely, containing electrolyte that absorbs the energy as the acid in a liquid form due to its porous material. It performs well during both high discharge cycles and long periods when not used often.
The Dual Purpose Trolling Motor Battery- A dual-purpose battery is a combination of deep cycle and marine batteries. It has stronger plates than the deep cycle battery, but can be recharged more easily than the marine battery. This type of battery is often recommended for use in smaller recreational vehicles, such as cars and boats.
The Car or Starting Trolling Motor Battery- A starting or car battery is less powerful and designed to provide power only until a car engine starts. It has a lower weight capacity, but a longer lifespan when used regularly for several years.
Internal Makeup of  Trolling Motor Battery- The internal makeup of a trolling motor battery can vary from one type to another. Most batteries have a positive and negative sides that will connect with the battery terminals of your trolling motor.
The Lead-Acid Wet-Cell Trolling Motor Battery- The wet cell is an older type of battery that has become obsolete with newer technology. It consists of lead-acid cells connected in a series and then plates inside the battery case that forms the electrolyte. The plates are made up of lead oxide, an electrochemical material used for traditional wet cell batteries.
AGM Trolling Motor Battery- AGM batteries are sealed by being encapsulated in a plastic synthetic material, making them water-resistant and able to be stored outdoors without risk of damage. The electrolyte is suspended in a gel, which prevents the acid from spilling. This type of battery is gaining popularity as they are more resistant to damage than other types of batteries.

Best Trolling Motor Battery Tips

Trolling Motor Battery Output and Capacity-

First, know that a battery’s output and capacity have no relationship to its physical size. A deep-cycle battery is usually taller than it is wide or long, but its power/energy capability is rated in ampere-hours (Ah). For example, a battery with an Ah rating of 100 will deliver twice the power of one with 50. A typical deep-cycle 12-volt lead-acid battery has an Ah rating of around 80 to 100. To work out how many amps you need for the boat’s systems take your amp draw from the main engine alternator. To find the amp/hour rating of your battery subtract 10% from the number you read on the label. For example, if you read 100 amps on your battery, then take away 10% (40 amps) and divide that number by 2. The result is how many Ah’s you should have to give it a fighting chance to make it through that day. That is assuming you are using a good quality battery like Kirkland lithium batteries or the batteries I use in both my boat and truck.

Trolling Motor Battery Maintenance –

Maintenance consists of changing out electrolytes every month or so and adding distilled water where necessary. Make sure you change them at least once a month (and more often during hot weather and in saltwater applications). Be sure to clean and check the battery terminals for corrosion regularly. Do not use a wire brush on the battery posts, but instead use a cloth to wipe any corrosion/factory-applied protective coating from the metal contact points.

Trolling Motor Battery Charging Maintenance –

Always turn off the charger before removing the battery from your boat or RV. Never overcharge your batteries. In fact, it’s good practice, in general, to disconnect your batteries after each use and store them separately when charging is not being performed. This helps to preserve their life between uses while at the same time allowing more frequent rotation between them (to prolong their lives).

Trolling Motor Batteries Maintenance Tips – 

If a battery is left unused for more than six months, its water must be checked and added on a monthly basis to prevent sulfation. If you have a lot of batteries stored, mark the date of the last usage on the battery itself with a permanent marker so that you can keep track of when maintenance is required. An easy way to tell when your battery needs water is to check it with an inexpensive hydrometer (which floats in the electrolyte) and note the reading. Next month, if your hydrometer reads less than 1.25 volts, it probably needs water. Otherwise, let them sit till next spring. A little maintenance goes a long way.

Trolling Motor Battery Run Time – 

When you are at the trolling motor or motor controller on your boat, it is important that you select the correct battery settings for your application; this will maximize run time. Most trolling motor controllers have a dual battery configuration option that provides automatic shut down if both batteries are discharged to dangerous levels. Before selecting automatic shut down, be sure to set the output of the controller to its highest setting so you can get longer run times out of each battery. If you are running 2 batteries in parallel and plan to use them at peak performance (no load), then set your controller’s setting between 20 and 30 amps per battery (to prolong their life).

Picking the Right Trolling Motor Battery –

There are many choices of trolling motor systems and many brands of trolling motors. The quality of the trolling motor depends on a variety of factors: what type of trolling motor (outboard, inboard, stern drive), what size (i.e., foot control or helm) is desired, and what type of boat is being used. The first factor that needs to be addressed is whether you plan to use a heavy lift prop or not. Most boats will benefit from an increase in power by running at high speeds with a heavy lift prop when you are charging the batteries for long periods such as during a weekend outing. You can also use a smaller prop and charge the batteries on a daily basis for a weekend.

Trolling Motor Battery and Setup-

In order to calibrate your trolling motor, you should always have the exact load in amps that your motor will be pulling, as this will tell you how much current you should set your trolling motor controller at to get the desired amount of power. The best way to accomplish this is to make sure your battery is fully charged, and then connect a fish finder (with live data shown) or digital panel amps meter directly to your battery terminals. Now start the trolling motor and pull up the boat’s anchor (or engage the boat’s windlass).

Best Trolling Motor Battery FAQ

How To Charge These Types Of Batteries While On The Lake?
The best thing you can do is connect the trolling motor battery charger directly to your cigarette lighter outlet and let it charge while on the water. Keep in mind that this method of charging will not be as effective because of low amperage due to engine noise and vibration. It’s best if you can find a place where there’s shore power so that you can plug it into an electrical socket. However, if you can’t then take the boat to a marina where there is ample shore power. It is highly recommended that you keep your trolling motor battery charged while on the water so that it will last longer.

How long will a 12v battery run a trolling motor?  There are two basic types of batteries: flooded and deep cycle. The first type of batteries have acid inside and they are designed to be flooded while the other type of batteries does not contain any acid. You’ll need a charger rated at 50 amps for these types of batteries while you can use a trickle charger if your trolling motor runs on 4 J or 6 J.

How To Wire A Trolling Motor To The Batteries?  If you’re using a dual battery system and your trolling motor is connected to one of them, then all you’ll need to do is connect the red clip on the wire directly to the positive terminal and then connect the black clip directly to the negative terminal. If you’re using a single battery system then take off your ground wire and attach it to both terminals.  If you wish, you can resist the corrosion by using a silicone spray or apply NoCorrode or another similar protection product on both terminals just before connecting them together.

Can I use a car battery for a trolling motor?  No, because these types of batteries are for marine use only.
How Long Should This Type of Batteries Last?  The average life span of a 12-volt battery is about four years. The average life span of a 24-volt battery is about seven years. On average, they should last about 12 years before you probably need to replace them and this value varies depending on how you treat your batteries and how often you charge them or when you put them in storage. If you have stored your batter}’s for an extended period of time then the % of performance left in it will decrease with time, this will cause the strength to become weaker.
Do you need to charge your trolling motor battery every month?  This depends on how often you use it and how you take care of it. If your battery is left standing around for a long period of time without being recharged then it will lose its effectiveness and discharge sooner. If your battery is left out in the sun then it will lose its effectiveness and discharge sooner, but if you use a trickle charger (not recommended) then it will not discharge as fast. You should charge your battery every 3 months but this varies depending on how you treat and store it so for it to last longer you should take care of it.
How often should I charge my trolling motor battery?  This really depends on the size of your motor and how often you use it. If you’re using a small one then once or twice a week would be good enough while if you’re using a big one that has lots of power then once a week is fine. If you’re using one of the new digital trolling motors then it takes longer to charge and discharge (depending on what you’re charging) so it’s recommended that you charge it every 3 months.

What is the best way to charge this type of battery?  You should use a marine battery charger rated at 50 amps and do not use a trickle charger. You can do this in either your house or the garage and you should let it charge up completely before you start using it. It’s also a good idea to check your battery every year because if you’re not using it for an extended period of time then there are chances that its performance will be diminished, this is why we always recommend that you take care of your boat’s equipment by keeping them charged. Take care of your battery too to prolong its lifespan.

How fast will a deep cycle battery discharge? This depends on how you use it, but if you leave it connected to a 12-volt system for a long time then it will discharge faster than if you keep it hooked up to an alternator. You should follow the directions that come with your marine charger and recharge the battery about once every 3 months. If you’re not using the battery then let it discharge out completely so that it has no charge left in it.

How long will a deep cycle battery hold its charge? This depends on how you treat your battery. If you’re not using your battery then it should last for about 3 months. If you’re using it constantly then it should last for about 2 weeks. The average life span for this type of battery is about 4 years, but this value varies depending on how you treat them.

How do I dispose of a deep-cycle marine battery? You can’t just throw them away into the garbage because they contain corrosive acid so before tossing them into the garbage make sure that they are completely drained out and remove all the caps that are on them.

Why are Deep Cycle batteries best for Trolling Motors?
Deep cycle batteries are designed to discharge their entire capacity many times over and can withstand many cycles of this type of use. While the engine isn’t running, the trolling motor draws a small amount of current from the battery to power electronics such as lights and sonar units. This continues until the battery is almost discharged (about 10% remains in most cases). Then it switches over to “float mode,” using less current but holding up the voltage to keep those last few percent from going out while it charges back up again.

How many amps do trolling motors draw?
The average trolling motor draws about 3 to 7 amps.

How long can a trolling motor run on a deep cycle battery?
Fully discharged batteries should not be used for extended such as long fishing trips. When the motor stops, you will not be able to start the engine again until it recharges the battery. Therefore, the boat must be returned to land and recharged. If you let the battery run down too low, you will not be able to get it started again.

What kind of charger do I need for AGM trolling motor batteries?
The best type of charger is an automatic charging system. These systems are designed to charge your trolling motor battery exactly as it needs to be, and not overcharge the battery like some chargers do. They will work great with AGM batteries as well as wet cell batteries.

How important is a Battery Warranty?
Most batteries have a limited warranty, usually around 1 year. Some longer warranties are available, but in most cases, they do not apply to trolling motor batteries. These batteries can use at least twice the abuse of 12 Volt car or truck batteries. They need more frequent maintenance and water testing than regular car or truck batteries. If the warranty on your battery is less than 1 year, you may want to consider a longer battery with a longer warranty.

How do I find what Group Size my Old Batteries are?
Most batteries are marked on the bottom with letters such as AGM or GEL. This stands for “Absorbed Glass Mat” or “Gelled electrolyte”. The initials come from the type of electrolyte used in each battery. The battery type also has a number or code which is usually 3 or 4 digits, sometimes letters. The first letter in the code is the size of the battery. If you have one battery, check it, and if it matches, your looking at the right group code. It is important to match both batteries in a set to have balanced performance and cycle life.

Are AGM batteries worth the price over Wet Cell?
Yes! AGM batteries are made by using glass mats to hold acid inside a battery. These mats are not the same as lead-acid batteries. They are made of specially blended glass that is resistant to breakage.

What Are My Battery Type Choices?
There are many different types of AGM Batteries on the market today, some with longer warranties than others. The most common type of AGM battery is the Wet Cell which has a 1-year warranty and great cycling capability, but it doesn’t have as good of a long-term storage life as an AGM battery with higher wet or absorbed electrolyte levels.
