Understanding Types and Features of best AGM battery:

The features of trolling boat batteries are mostly out of head terms. You will hardly understand what these terms stand for. Yet, it will be easy for you to sort the best power cells for your trolling motor knowing a few specific things. And, when you take the right decision for choosing the best electric back up source, you are confident while getting out on the water.

Moreover, you will find different types of Boat Batteries in the market. Each kind has its unique applications and features. Besides, some kinds of batteries are also the most recent upgraded version.

Hence, let us talk about the features you need to sort the best trolling motor batteries.

Dry Cell and Wet Cell Batteries:

Dry Cell Battery! Are you thinking which one it is? It is commonly known as the Sealed Battery. From household items to your favorite fishing boat, this type of battery is a common thing. From your torch to your cell phone, this Dry Cell Battery is everywhere. This battery indeed contains a paste or mat of its materials. Still, you will be surprised. It’s not entirely sealed. What! Yes, you will find no lead-acid battery, which is truly sealed. As the reaction produces Oxygen and Hydrogen, these batteries also keep a way to release the excessive pressure. Otherwise, the battery could explode.

Again, Wet Cell Lead Acid is just the opposite of a Dry Cell . Most of the anglers know it as the Flooded Cell Battery. Actually, Lead Acid Batteries are the ancient type of rechargeable power cell battery. Indeed, this is the earliest type of rechargeable battery. And, you will always need to keep it upright when it contains unsealed lead-acid. Besides, you have to ensure well ventilation for the battery. Why? It’s because it produces hydrogen gas while overcharging.

However, the Scientists have made more advanced Sealed Wet Cell Trolling Motor Batteries nowadays. You will now find Absorbed Glass Mat (AGM) batteries as well as Gel Batteries for your trolling motor. AGM and Gel boat batteries are also Wet Cell batteries that use advanced Valve-Regulated Lead-Acid Battery (VRLA) technology. We are now also going to discuss these types of batteries bellow.

Valve-Regulated Battery:

The Valve-Regulated (VRLA) battery is an advanced liquid electrolyte Lead Acid Battery. You will need no regular addition of water for your battery cell. Therefore, it will provide you a maintenance-free extra service. Actually, VRLA batteries are also wet cell batteries that have a safety valve for pressure relief. VRLA batteries usually are spill-proof as it uses comparatively less battery acid.

Here comes two more types of VRLA batteries. And, one of these  is Absorbed Glass Mat (AGM) battery, and the other one is the Gel battery. However, both types are completely sealed. And, you will find these battery cases are adequately enclosed. As a result, these batteries don’t need ventilation ways. In that way, these batteries serve as an essential facility. You can put these energy cells wherever you want on your boat.

AGM Batteries:

AGM deep cycle cells have a glass mat separator to hold the electrolytes. Generally, these batteries always offer a longer lifespan. You will love an AGM battery as it serves you with a leakage-proof stable power backup source. Another feature of a best AGM battery is its temperature tolerance capability. Besides, its vibration resistant uninterrupted power supply will undoubtedly give you a comfortable journey in the water. Moreover, its slow discharge rate will also make you smile.

Gel Batteries:

Like an AGM, a Gel Battery also uses Suspended Electrolytes. But, the main difference is the electrolyte. Gel Cell uses gelled electrolyte with Silica Additives. Besides, this power sources chemically use Calcium instead of Antimony in the Lead plates. Thus, these  power sources of trolling motor are extremely shock-proof as well as spill-proof.

Similarly, it can work efficiently at both high and low temperatures. These features made a Gel Battery a completely maintenance-free energy backup source. Again, a Gel Battery has a lower slow discharge rate compared to an AGM battery.

Deep Cycle and Dual Purpose Batteries:

When you want to start your boat engine, you will need a starter battery. A starting battery gives a high amount of energy at a time to power up your trolling motor. And, while starting the boat motor, it also discharges a more considerable amount of its power.

You will always look for a battery that gives a consistent and steady power supply. So, you should know the features- Dual-purpose and Deep cycle. The battery companies have used upgraded technology here to discharge the preserved power slowly. This will give you a steady and consistent power supply for more hours.

Again Deep cycling feature is designed for discharging its capacity over a more extended period. Deep cycle batteries are an angler’s best support in the deep water. You will never need to worry about the power backup. Normally, with a fully charged deep cycle battery, you will get electric power back up for hours.

Best Dual Purpose Marine Battery will serve you both the starting and deep cycle features. When you need to start your trolling motor, dual purpose battery is your best helping hand. Again it will give you a long battery backup too. That means if you buy a dual purpose deep cycle cell, it will take care of your entire boat. So, this feature always meets your dual purpose. Everyone expects to start his trolling boat engine easily. At the same time, he needs deep cycling performance for longer power backup. However, when a battery starts the boat engine, power backup goes lower for the rest of its duties.

Thus, it would be best to have a Deep Cycle Battery for running your trolling motor. A deep cycle battery is specially designed for long time reserve capacity. It doesn’t discharge a larger amount of its capacity at a single time. Therefore, for more extended power backup, a Deep Cycle Battery is better than a Dual Purpose Battery.

So, what can we say now? You can choose a Dual Purpose Battery when you need an all-doing energy storehouse. But, a Deep Cycle Battery is the right choice when you are thinking about your Trolling Motor.

Float use and Cycle Use Batteries:

Do you need a standby alternative power source for your Trolling Motor Boat? Then you are thinking about a Float use Battery. It’s a continuous alternative source of your primary source of power.

On the other hand, a Cyclic use battery works just like a Deep Cycle Battery. That means you can discharge as well as recharge this battery continuously. When you pick a Cyclic use Battery, you are getting a power backup of years’ lifespan indeed.

Things that One Should Consider Before Buying Trolling Boat Batteries:

You now know about the features of different types of Trolling Motor Boat Batteries. So, you have confidence about which marine battery you need. But, still, there are more things to know about. You need to know these things to fit your battery with the Trolling Motor best. It will help if you consider these factors after listing the best trolling motor batteries.


Size and Weight of Trolling Motor Battery:

The weight of a Trolling Motor Battery depends on its size. The larger the size is, the heavier is the weight. Most anglers know that with a large group size battery, you will have higher Ampere-Hour capacity. Do you need to fish in a windy environment? Then you should consider a large Group size Marine Battery. At the end of the day, you will realize how much benefit you got from it.

Battery Group:

Moreover, if you observe thoughtfully, you will find out an interesting thing. Every marine battery has an “M” at somewhere of its group number. Here “M” refers to Marine Battery, determined by Battery Council International (BCI). There are several group-size trolling motor batteries in the market. Some of these are 24M, 27M, 31M, and 34M, and so on.

Boat Space and Capacity:

Besides, you should also measure how much free space you have on the boat. When you have work for a long time in the deep water, you would need more space on your boat. It’s because a large size battery will be then perfect for you.

Again, the weight also depends on the battery type. A Gel Battery is comparatively heavier than an AGM Battery. But, you know, Gel Battery gives more runtime as well as maintenance-free better service. So, what size battery will you choose now?


The most important thing about a battery is its power system. That means the Voltage (V). Indeed, you will see most of the Deep Cycle Marine Batteries are of 12V. However, you may need a 24V or 36V battery to support your Trolling Motor. In this case, you will need to connect multiple batteries in a series circuit. Sometimes, you can connect multiple batteries in parallel, depending on your need.

Ampere Hour:

You will see several ampere-Hour (AH) units on different marine batteries. This AH defines how much amperage the battery can supply in one hour. That means you can estimate the total electric-store capacity of the battery with this Ampere-Hour.

You would need higher or lower AH depending on your boat, as well as on your runtime. For say, you have a small fishing kayak. And, your friend has a large trolling motorboat. Now, you will surprisingly notice that a 55 AH battery might serve you the same runtime as a 200AH battery gives to your friend’s boat.

Benefit of higher Amp Hour:

So, you should select the AH according to your boat size and speed. Yet, if you consider higher AH for a small boat, you would get an added benefit. Which is that? You will have a greater runtime. And you know that the more the runtime is, the more time will you have for fishing.

By the way, a 24 lb thrust trolling motor draws around 27 ampere on average per hour. In comparison, a trolling motor of 55 lb thrust draws 55 ampere per hour.

Reserve Capacity:

Reserve Capacity is the most important thing that an angler considers first. Theoretically, it means the total time a battery needs to supply a certain amount of amperage before downing to discharge fully. Typically, when a 12V Marine Battery goes to below 10.5V, it is considered completely discharged. For example, the best battery for trolling motor with 120 Minute of Reserve Capacity usually supplies 25 amperage constant loads for 2 hours before fully discharged. But, practical experiences show the actual backup hour usually is a bit lower than the theoretical hour. 

However, calculating this parameter is very important to select the best Deep Cycle battery. The higher the reserve capacity is, the longer will be your fishing on the water.

Cold Cranking Ampere (CCA) and Marine Cranking Ampere (MCA):

Cold Cranking Ampere parameter is very much essential to start your boat engine in cold weather. When you are using a Dual Purpose Battery or a starter battery at almost freezing temperature, you will need a better CCA rating. Actually, the CCA rating shows how much load a battery can provide at 0 degree Fahrenheit for 30 seconds.

However, in a warm-weather area, you would need to look for other criteria rather than emphasize on CCA. You know the starting power of a battery decreases over time. So, you will need a higher starting power battery when you are in a cold-weather zone. For this reason, CCA is a very important rating of a battery while considering very low-temperature areas.

On the other hand, Marine Cranking Ampere (MCA) rating is somehow the same as the CCA rating. The basic difference is the considered temperature. Here, the load is assessed at 32 degree Fahrenheit for 30 second.

Charge Rate (C rate):

The Charge Rate or C-rating of a battery shows how quickly it goes to empty. You can measure how long a battery could take to charge or discharge fully. For example, a 200 AH battery with a C-20 rating will need 20 hours to be charged entirely with a 10 amp load per hour.

Now, let us surprise you. When a battery is charged faster, it will store less amount of energy. Frankly, when a battery is charged or discharged more quickly, it produces more heat.  This heat reduces the energy consumption capacity of the battery. That’s why the calculating C-rating is a very much essential criterion while buying a marine battery. So, C-rating is one of the vital criteria for being the best AGM battery.

Depth of Discharge (DOD) and State of Charge (SOC):

Depth of Discharge (DOD) stands for the amount of power a battery has used. Always, you should know this term for your battery longevity. For example, 70% DOD means you have already used 70% electric power of the battery. The range is 0% (fully charged) to 100% (fully empty). The truth is that the Experts always forbid discharging your battery deeper. Otherwise, it will harm your battery lifecycle. Hence, it would help if you always kept an eye on your Marine Battery for the DOD rate.

On the other hand, SOC means the State of Charge. It’s just the opposite of DOD. SOC shows how much charge is left in your battery. Here you only need to alter the range- (0%- empty and 100%- fully charged).

Then, what do 70% SOC and 30% DOD mean? This means you have 70% power left in your battery, as you have already used 30% of the reserved power.

Marine Battery Charger:

Different kinds of chargers are there for different types of batteries. An AGM battery charger is not best suited for a Gel Marine battery. There are regular, onboard and smart chargers and even some portable chargers too. A smart charger always cares about your battery by restricting overcharging. Again choosing a non-compatible charger for your deep cycle battery will result in money expense. You will need to buy a new battery within a few years. Nowadays, most battery manufacturers have their own charger recommendation. You should always follow their guide while charging. Besides, a shock-proof vibration absorbent battery case with the charger will keep your battery alive for years.

You can have an onboard charger for your marine battery. But if you have space limitation on your kayak, canoe, or small Minnkota trolling boat, this charger will be a hassle. In this situation, a portable charger will be your best pick.

However, you should know that rapid charging is not always good for your battery health. The more the charging time is, the better will be the reserve capacity as well as lifespan.

Connecting a Trolling Motor Battery in Parallel or Series Circuit:

You can connect your trolling motor boat battery in parallel or series, as you required. When you need to stay long in the deep water, capacity is the most vital part to consider. So, you now need to increase the capacity? Well! It would help if you then connect multiple batteries in parallel as required. For example, if you need 60 ampere hour capacity for your motor boat, you need to connect two 30 ampere hour batteries in parallel. Here, it would be best if you keep the same voltage batteries in the circuit.

When you need extreme voltage for your boat engine, connect multiple batteries of the same specification in a series circuit. This will increase the battery voltage leaving the capacity the same. Here is an example. To have a 24V power voltage, you need to install two 12Va batteries in a series.

When you want a parallel circuit, connect one positive terminal with another positive one and the negative with the negative. But, for a series circuit, connect every positive terminal of one battery with the negative terminal of another battery.

Maintenance and Safety Issues for any Marine Boat Battery:

Nowadays, the advanced battery technology gives the boaters relief from the Trolling Motor Boat Battery’s regular maintenance. Besides, you need to worry less about your safety issues. Yet, there are few factors you should always keep an eye on. What are those? Let us talk here.

  • You should add distilled water to your regular Lead Acid Flooded Battery. You should refill it every 2 to 3 weeks. Why? The chemical reactions in the battery always result in a decrease in water. Be careful. Always ensure distilled water before pouring in the battery. However, for a Sealed Lead Acid AGM or Gel) you don’t need to add any water.
  • Always keep an eye on the State of Charge (SOC) and Depth of Charge (DOD). Always the Experts recommend not to go below 50% DOD for better Battery health.
  • Be careful when connecting multiple batteries in the circuit. Never use boat batteries of different power and capacity in the same circuit. It will always cause you an early expense for buying a new battery. Besides, it may cause an accident at any time.
  • Never empty your battery. It definitely reduces the battery life cycle. Experts observed that a10% less discharge might cause 2 to 3 years more lifespan as a result.
  • Cleaning battery top is always a good thing. It will help you by reducing the risk of more expenses.
  • Check your battery connections regularly. Always keep the connections tighten.
  • Always be careful to use a charger. You should use the best charger that is recommended by the battery company.
  • Do not overcharge your battery. Otherwise, it will result in a decrease in the efficiency of the battery. This is why expert boaters recommend keeping an eye on the battery while charging.
  • Do not use your battery while charging.
  • One special tip for you. You know there are cold cranking batteries as well as marine cranking batteries. However, don’t use an only-cranking battery as your trolling motor power backup. Indeed, you should use a dual purpose or a dedicated deep cycle battery as the energy power source.

Impact of Lead-Acid Trolling Motor Battery on Health and Environment:

You can never think of a day in the water without a high-performance Trolling Motor Battery. It always makes your fishing worthy and comfortable.

Yet, every Lead Acid Battery harms health directly or indirectly. Actually, Lead is such a thing that it is never digested in the body. When it enters the body, it is stored in different parts of the body. Lead Contamination is a perilous health-hazard problem.

According to the World Health Organization (WHO), Lead Contamination has many kinds of toxic effects on the human body. As a result, it can cause many diseases, including gastrointestinal, hematological, and even neurological problems. Moreover, health experts also said that Lead pollution could also affect reproduction as well as the endocrine and cardiovascular system.

Besides, all the other battery chemicals have their individual negative impacts on health too.

Battery Disposal for Environmental Benefits:

So, you should be careful about the disposal of used Boat Battery. You should always search for the proper authority for the perfect and safe disposal of your used Lead Acid Battery.

However, many battery retailers offer a discount on the return of any used Lead Acid Battery. The special concern on proper Lead-Acid battery can make a healthy better environment for the young.

Frequently Asked Question:

Frequently Asked Questions

At the end of any discussion, there will always be some questions. We have also sorted a few questions. Actually, most of the boat battery users ask about these. So, let us discuss these.

How Long Do AGM Batteries Last?

First of all, the life span of an AGM battery is always greater than the normal flooded battery. Again Gel Battery is of comparatively higher life cycle than AGM battery. Normally a flooded battery lasts 3 to 5 years. In this comparison, an AGM battery provides 5 to 7 years continuous service. But, for longer service, you should not allow depth of charge less than 50%. Again, users claim that the best trolling motor batteries can run for even 10 years or more.

Why Deep Cycle Battery is Considered the Best for Trolling Motor?

Every Deep Cycle Battery has a lower discharge rate. This allows the battery to gradually discharge its power over a longer period.
