There are some other features, which we will now talk about.

First of all, the ML55-12SLA is a 55-AH, 12-Volt Sealed Lead Acid battery. It’s maintenance-free and offers a good, long lifespan.

But we are not interested in what the manufacturers claim, rather we would like to test it out in real life scenarios.

And that’s what we have done. At first, we would happily like to report that the manufacturers claim to seem to be on point. The calcium-alloy grid does seem to offer a fair amount of performance numbers than some of its big brothers.

Like most of the products featured in this review, this battery also features the Absorbent Glass Matt or AGM technology, making it a potent option for your trolling motor. It does feature a valve-regulated design, which brings its value up by some considerable degree.

Features like long discharge rate and longer operating temperatures are quite common these days. And to tell you the truth, a battery without such features doesn’t seem to be worth it.

But we are happy to inform that the ML55-12SLA does a good job at satisfying the previous to criteria. Unlike most of the existing options, the ML55-12SLA is capable of offering great battery life. Also, providing consistent performance even in the hot weather conditions is something of an advantage. Furthermore, the battery is usable in orientation, which is a plus.

One small thing to mention here is that the ML55-12SLA is capable of handling a wide variety of applications including consumer electronics, power tools, garden tools, power sports and much more.

From all the features, we can see that it is a tough contender for the best battery for the electric trolling motor. So, if you are thinking of getting something which will not only handle your trolling motor but will also handle other electronic accessories, then you will want to check it out.

From the specs, we find that it’s a 12-volt 18-Amp 20-hour Sealed Lead Acid battery. All the nuts and bolts are included, as with all other products in this category.

But these are not the key features.

When it comes to features, its got quite a lot of them. For instance, The High-Impact Resistance Battery case offers superior support and resistance from shocks and vibrations.

Of course, similar products may offer the performance of the same caliber. But from what we have seen in our testing, this one holds out just as well. The non-conductive ABS plastic offers a solid performance, which is commendable.

For the past couple of years, we have seen several releases from their side which offer solid performance at a competitive price. Also, the reliability of their products is right on par with some of the prominent players out there.

So, what’s so special about the Power-sonic trolling motor battery?

At first, and its perhaps one of the key selling features of this particular model is its weight. It is right in line with some of the lightest models out there. And, of course, you would want a lightweight battery for your trolling motor for better maneuverability and flexibility.

Then there’s the implementation of the Absorbed Glass Matt or AGM technology. This Sealed Lead Acid battery gains a few extra performance points because of the implementation of such a technology.

The 12-volt 35-AH motor also shines in the battery life department as well. Not only does it offer good battery life, but the longevity of it is also commendable. Also, take note that the battery offers consistent performance to a certain degree, even in significantly hotter environments.

So, what’s the verdict overall?

Well, unlike some of the other products we reviewed so far in this best trolling motor battery review, we see that it has similar features to that of some of the reliable brands. But it stands much lighter than some of the currently existing brands, which is, as we mentioned earlier, is one of its key selling points.

So, for the final judgment, we would like to call it the best lightweight trolling motor battery.

All of the products which we mentioned above has some distinct feature to make it stand out. From our point of view, we think all the products are capable of being on your shopping cart.

Sadly, that will never happen!

So, what’s so special about this power center?

First of all, it is not your average product. It’s a state-of-the-art battery case for anglers and fishermen alike, enabling them to be faster and more active in making their move. Now it is more like a battery holder and doesn’t come with batteries installed. But that’s not why we are reviewing this.

It’s the overall usability which kinda compelled us to put this product at the very top of our list. For small-sized boats, there’s clearly no match for it. If you want the most minimal battery case for your boat, then this is the one to get.

But of course, you wouldn’t want something that can only hold batteries. There should probably be a bit more.

Trolling Motor Battery Buying Guide 

Warning!

This part is going to be a bit long. Better get some coffee while reading it!

There’s a pretty good explanation for this. First, we want to cover all the small details in brief. Second, we want to point you in the right direction as to how you should choose the correct trolling motor battery for yourself.

So, let’s get started.

Budget

This a hard topic to cover.

Trolling motor batteries come with different price tags. But for a typical user, a price tag around 30$ to 90$ should be plenty. But be aware, there are other high-end options out there. Also, the price range varies on the type of battery you want to purchase. We will give you a better idea of this in the next section.

So, how will I justify the pricing?

The only simple solution we can give you is that you can decide on a budget first. A person can’t be any wiser if he or she decides on a specific budget to get on with. Maybe, once you have eliminated the out-of-the-range options, then you can start going through the choice which meets the desired price point.

It actually helps save a couple of bucks if you only have a limited budget. So, plan your budget to get the best possible results.

Battery types

It is one of the important things to know if you are shopping for a battery. This section may help you to make choices for other electrical appliances as well.

We will only be covering the major classifications here. Generally, there are three key battery types:

Wet or Flooded Lead Acid

You can easily find these batteries for a lot cheaper. The key reason behind it is that it is pretty easy to manufacture. There are quick and easy methods to manufacture these. Of course, the quality may depend on it.

These batteries typically last for 1.5 to 2-years, even more, if you can manage it. But such batteries are losing their ground because of better available technology at lower prices.

So, we would recommend it only if you don’t have too much cash to spare. They do require frequent maintenance, so you will need to put up with that as well.

Absorbed Glass Mat

These are the ones you should probably get!

Absorbed Glass Mat technology used to be a lot pricier back in the old days. They used to be high-end batteries a couple of years back. There are two simple reasons behind it:

First, they offer a steady output of power, even in tough weather conditions. Second, they will last a lot longer than their Lead Acid counterparts.

For these reasons, AGM batteries “used” to have higher price tags. But, in recent years, we have seen a significant decrease in pricing, which allowed average consumers to get these batteries at a much cheaper rate.

Almost all of our products in this list rely on the AGM technology. And we are sure you now know why!

For the best value for the money, our recommendation would be for you is to get an AGM battery for that steady performance and longer lifespan.

Gel

These types of batteries, as you may have already figured out, has a gel-like substance to make the whole thing work.

Now, these types of batteries haven’t had that much of a luck in the market. But if you do feel the need to do some research, then you are welcome to do so. But, for now, we would not recommend giving any thought on such an option.

Weight

It is an important factor, but you shouldn’t take it too seriously!

For the weight, it is better to consider it only if you are getting dragged back. Other than that, we don’t really think itstoo big of a deal.

But, for the most part, anglers or fisherman typically prefer around 30-lbs batteries for their trolling motors. It's not become a standard by any means, but it does that job better than other options.

Amp-hour rating

It is another crucial fact to take into consideration.

The Amp-hour rating can be simply described as the amount of current (measured in amps) can be discharged in an hour. For example, if you have a trolling motor rated at 20 AH, then you may have a batter which can produce 2-amps for 10-hours or 5-amps for 4-hours or 1-amp for 20-hours. It’s as simple as that.

For the sake of simplicity, we will only say this: the more the AH-rating, the better.

Now there is one thing to keep in mind here. If you have a heavier boat, then naturally you will be losing current much faster. So, do keep that in mind.

Cold Cranking Amps

Cold Cranking Amps or CCA ratings aren’t particularly important. This rating is a measure of the current released on the first 30-seconds of power up at 0-degree Fahrenheit.  If you don’t have a battery which is capable of maintaining two functions, then you can ignore this part. For trolling motor batteries, it's not particularly needed, but the more information you have, the better.

Lifespan

The lifespan of a trolling motor is clearly an important one. You wouldn’t want to spend money on a battery which won’t last long.

For this information, it is better that you check the manufacturer’s website. Information like these are crucial, and they may help you in the long run.

Dual purpose vs. deep cycle

The name may be a bit confusing at first.

From the title, you may have no idea what we are talking about. But we are talking about batteries here.

Dual-purpose batteries simply serve a “dual” purpose. For instance, the can both crank the engine and keep a steady flow of electricity running. These types of batteries are well-suited for the whole boat.

But if you want something specifically for your trolling motor, then a deep cycle battery may serve you better. These types of batteries are designed to discharge a large amount of their electrical capacity over a certain span of time. This time span is usually long. For this reason, deep cycle batteries tend to have longer lifespans.

In the end, it’s all about making a choice. If you want an all-around battery for your boat, then a dual-purpose battery may be the correct choice. But if you want something specifically for your trolling motor, then you should probably buy a deep cycle motor.

Maintenance

Recharging your battery to its full capacity is always recommended after a fishing trip. It will help maintain a better lifespan.

Also, as we mentioned earlier, flooded lead-acid batteries need a lot of maintenance, and on a regular basis. So, you may want to consider your options.

Finally, ‘Sulfation’ or sulfur build-up on the battery plates is a constant problem and requires maintenance. It is a problem with the flooded lead-acid batteries.  So, be mindful of that. If constant maintenance concerns you, then you may want to choose an option that requires little to no maintenance.

Customer support

If you want the best all-around trolling motor battery, then it is prudent that you inquire about the customer support first.

Having a good customer support is a key factor in many cases. If you are unlucky, as it so often happens, you may end up with a bad unit. In such case, without having a proper customer support, getting the right support for fixing the issue or even refund may be impossible.

So, make sure to have a visit to the manufacturer's website for more information.


FAQ: Some important queries

We hope this section helps you out to find the answers you are looking for.

Q: Is it wise to add any water or any other additives?

Ans: We would strongly advise against this idea. Modern trolling motor batteries don’t really require any form of addition or maintenance. But for the batteries which need to be maintained, we would recommend that you use distilled water to top them off.

Q: How can I dispose of my battery?

Ans: Typically, the manufacturer you brought it from are also authorized in most cases to help you dispose of the battery.

Q: Should I expect similar performance from all Lead-Acid batteries?

Ans: Of course not. Different batteries have different lifespans. Also, it depends on the manufacturer as to what technology they are using.

Q: Name some possible battery explosion causes?

Ans: Poor ventilation, lack of proper connectors, even improper maintenance can sometimes cause your battery to explode.

Q: When do I change my battery?

Ans: It basically depends on some things. If you are experiencing slow or interrupted starts, blinking indicator lights or any such symptoms, then you may want to consider getting a new battery for your trolling motor.
