6 Best Trolling Motor Battery - Reviews

1. Optima 8016-103 D34M Marine Battery

Optima 8016-103 D34M Marine Battery

The Optima brand is one of the most popular and most well-known names in the trolling motor battery industry, and this particular 8016-103 D34M BlueTop is a bestseller.

Optima color-codes its batteries to specify how it should be used, and a regular BlueTop is used as a dedicated starting battery.

This regular variant uses a dark gray case, and it’s different from this other version that uses a light gray case. This time, it can be used for both starting and deep cycling operations. What this means is that it is a very versatile battery.

While it is popularly used for trolling motors, it’s equally often seen as a battery for many camping sites. It can be used to power both boats and RVs that use lots of electrical accessories. This comes with a 55Ah rating, so it can last for a while.

What’s more, it’s very durable and long-lasting. The vibration resistance is terrific, as it is 15 times more resistant than a wet-cell. It can also last for a very long while since the number of recharges it can take before it fails completely is 3 times as much as the cheaper batteries.

This is an AGM battery, and it is maintenance-free. You won’t need to add distilled water to it, as it is completely encased. This encasement assures you that it is spill-proof, which means you can mount it in virtually any position. This weighs 43 pounds, which isn’t too bad considering its output.

It measures 10 by 6⅞ and it is 7 and 13/16 inches tall. It performs brilliantly. As a starting battery it offers 750 cold-cranking amps, and that means it can start your battery even if the weather is bad. It also offers 870 amps at 32 degrees F. It also offers a reserve capacity of 120 minutes.

It can discharge 25 amps for 120 minutes when used at 80 degrees F (that’s 26.7 degrees C), before the voltage goes down to 10.5 volts. It recharges quickly, and with 100 amps to recharge you only need about 35 minutes to get 90% charge capacity. That’s due to the low internal resistance.

However, you will need to use its own charger to keep it from overcharging. Also, you’ll need to follow the charging instructions to the letter if you want to take care of the battery properly.

Pros:

  • It can start a motor with no problem even at 0 degrees F.
  • It can help power boats laden with lots of electrical gadgets.
  • It doesn’t take long to recharge.
  • It can last for as many as a thousand recharging cycles.
  • Your boat doesn’t have to deal with a battery that’s too heavy.
  • You can mount it at any angle because it’s spill-proof.
  • It doesn’t need maintenance.
  • It won’t overcharge when you use the right charger.

Cons:

  • Without the right charger, you may end up overcharging the battery.
  • There are also a set of instructions you need to follow when you recharge it.
VMAXTANKS Vmax857 Tm AGM

This is another famous brand among batteries of this type, and it’s a perfect example of how one battery can be better than another, even if they offer the same Ah rating.

The VMAXTANKS vmax857 Tm AGM battery  comes with a 35Ah rating, yet in many ways it’s clearly superior to others that also have 35Ah.

This is extremely durable, and it’ll last long than your typical battery. That’s because it features premium-performance, military-grade metal plates, and they’re thicker to boot. This makes it stronger, and it’s able to withstand vibrations better.

It also has a robust and long-lasting outer casing that’s made of durable and extra-tough ABS plastic. This is designed to be used for 18 to 40-pound thrust trolling motors. It’s an AGM battery meant for deep cycling operations.

It works great for 30-pound thrust trolling motors. It can run for at least 5 hours at low speeds. This is great for small boats, as it only measures 7.7 inches by 5 inches with a height of 6.1 inches. It’s also only 25 pounds in weight. 

 It’s also a green backup power alternative to generators if you want something in reserve to power your laptop at home if the power goes out. It also has enough power to run your TV and a DVD player if you’re camping. It doesn’t really need maintenance at all, and it can be positioned at any angle. 

It’s actually quite tough and it should last you for a long while. It’s portable too, as the small size and light weight is matched with a convenient handle. If you’re in need of a light and compact battery with enough power for your boat, this is it.

Pros:

  • It has enough juice for several hours on a small boat at low speeds
  • It’s very light weight
  • It’s very compact
  • It’s spill-proof so you can set it at any angle
  • It’s very durable
  • You don’t need to do any maintenance for it

Cons:

  • For best results, you’ll need to get the VMAX BC1204 12V 3.3Amp charger
  • It’s very limited if you have one to use on a campsite
  • It cost a bit more than other brands
Mighty Max 12V 35AH SLA Battery

The mighty max battery is another 35Ah trolling motor battery, except this time it’s a bit more affordable.

Yet it offers several terrific features that you may not expect from a battery at a lower cost.

First of all, it’s quite compact. It measures 7.68 by 5.16 by 7.13 inches. It’s also not that heavy at 23.15 pounds. It’s also an AGM battery that’s spill-proof and it can be used for a wide range of operating temperatures. It’ll last long, regardless of whether you’re using this for high or low temperatures.

It’s also resistant to vibration and shocks. Since it is spill-proof, you can mount it at any angle. You can use it in indoor or enclosed settings as it won’t leak at all. You don’t have to do any maintenance on it either.

Use this on a Minn Kota C2 30-pound thrust trolling motor (or any other brand in the same range, for that matter), and it will offer at least 3 hours or so of service even at middle setting. With an RC, you can coax about 45 minutes of performance before you’ll need to recharge it.

Pros:

  • For 30-pound thrust trolling motors on a small boat or canoe, you can spend 2 hours on the water and it may still have more than half of its power.
  • It’s easy to install at any angle as it is spill-proof.
  • It’s doesn’t occupy as much space.
  • It’s light in weight, which again makes it ideal for small boats. It’s works on a kayak.
  • There’s no need for maintenance.
  • It’s reliable.
  • You don’t really need a special charger for this.

Cons:

  • Since it’s rated for just 35Ah, you can’t expect it to work all day, and it’s not a good option for week-long trips on the water.
  • It can take a while to recharge.
Interstate Lead Acid (AGM) Battery

Again, we have a 35Ah battery. Many find the 35Ah rating good enough for several hours of leisurely travel on the water, and this battery from Interstate Batteries works very well indeed.

First off, the size may throw you off and you may think that it doesn’t offer enough power for your needs.

Actually, Interstate Lead Acid (AGM) Battery especially designed to be compact, since it’s also meant for use in various types of medical equipment such as electric wheelchairs. It measures only 7.7 by 5.2 by 6.3 inches, and it only weighs 23.8 pounds.

For use in boats, it is exceptional. It has enough power in its compact design to provide up to 6 hours of use in a 9-ft inflatable boat. But you can use this for many other purposes. Aside from medical devices, it can also help power electrical gadgets in your RV or trailer.

This is an AGM battery, and of course it is spill-proof. You can install this at any angle you like. You don’t need a special charger for it either, as you can use your regular 12V battery charger.

Pros:

  • It’s quite compact, which makes it suitable for kayaks and canoes with trolling motors. It also fits in well with cramped RVs.
  • It’s also not heavy at all, and again that makes it ideal for small boats where load capacity is a constant concern.
  • Despite its small size, it offers enough battery power per charge for several hours of leisurely travel on a motored kayak.
  • You don’t need a special charger for it.

Cons:

  • You shouldn’t expect to use it for the whole day on your boat, nor can you expect it to power a lot of electrical gadgets when you’re camping.
  • Its recharging time is average.
Mighty Max 12V 55Ah Motor Battery

What if you plan on spending a lot of time on the water and you’re not keen on traveling at the lowest speeds?

If that’s the case, then perhaps this 55Ah AGM battery from Mighty Max will suit your needs.

Upgrading from a 35Ah battery to this will be a pleasant surprise for you if you’re using a 30-lb thrust trolling motor. Instead of staying at the lowest sped settings, you can expect up to 4 hours of service even when you’re constantly at full speeds.

You can even get 6 hours if you keep the speed down to medium. Even after these conditions, you may find that you still have 60% of battery power left. Perhaps you’re concerned that with greater power you also have to contend with much greater size and weight that your boat cannot handle.

While it’s true that this is bigger than your typical 35Ah battery, it’s not bigger by that much. It only measures 9.02 by 5.43 by 9.13 inches. If the 9-inch height is a problem, you can set it up on its side since it is spill-proof so you can set it at any angle.

It’s also not much heavier either, so even if you have a kayak it’s not an issue. This Mighty Max weighs just 38.6 pounds, and that’s only about 14 pounds heavier than a 35Ah battery.

It still comes with the usual outstanding features that Mighty Max batteries of this type are known for. It doesn’t need maintenance and it can withstand vibrations and shocks. You can use this even in low or high temperatures.

Pros:

  • It offers you more time on the water, and you can go faster too without draining the battery quickly.
  • It’s still not much bigger than a less powerful battery, and you can set it up at any angle to suit your space limitations.
  • It’s not all that heavier either, so you don’t really worry too much about the load capacity of your boat.
  • It’s resistant to shock and vibration.
  • It can last for a while, even in extreme temperatures.

Cons:

  • If you do happen to drain this, it can take you up to 30 hours to recharge this fully on a trickle charge.
  • If the 35AH battery is already almost exceeding your load capacity, then the extra weight may be too much for your small kayak.
VMAX MR127 12 V 100Ah AGM Battery

Just about everyone who understands the specs of the VMAX MR127 battery will appreciate its outstanding features.

It may not be designed as a starter battery, but once get going you’ll keep on going.

With its 100Ah rating, you can pretty much expect to last a very long time on the water, even if you’re using a powerful motor. It’s not just limited to your usual 30-lb thrust trolling motor. If you have a 40-pound thrust motor and you plan to go fishing, this’ll do well for you.

It can last up to 12 hours with your motor at the lowest speed setting. Put it on medium speed, and you’ll still get more than 7 hours of service. In fact, with this you can get more than 2 hours (2.4 hours, more or less) at constant full speed instead of the few measly minutes you get from a smaller battery.

If you have a 55-lb thrust motor, this will still work wonders for you. You’ll get 8½ hours at the lowest speed setting, a little over 5 hours at medium speed, and about 1 hour and 40 minutes with the sped at full throttle.

Of course, with its 100Ah rating this is a bit bigger than your usual battery. It measures 12.1 inches wide and 6.7 inches deep, with a height of 8.2 inches. It’s substantially heavy too at 68 pounds. But if your boat can take the size and weight of 2 of these connected by a 12V parallel connection. 

You can go on the water twice as long. This is an AGM battery, so it’s spill-proof, nonhazardous, and maintenance-free. It can be recharged through various means, including a vehicle alternator, a solar panel, or a wind turbine. 

You just can’t use a smaller charger for this, nor can you use a maintainer to charge it. The body is made of tough plastic, but it’s actually designed to fit in a power kit. The metal on those kits will help protect it further from any sort of damage.

Pros:

  • You can go fast on the water for a very long time.
  • This can last for many years.
  • It recharges in half the time it takes to recharge a standard battery.

Cons:

  • It’s bigger, heavier, and more costly than your usual boat battery.
  • You’ll need to put it in a power kit to really keep it going.

How To Buy Trolling Motor Battery

How do you pick the best trolling motor battery among all these choices? When you’re doing your online research, you will probably check the price, the reputation of the battery brand, and the customer reviews. Here are some specific factors to consider as well when you read these reviews:

There are 3 basic types of trolling motor battery to choose from:

1. Wet-Cell 

These are your basic deep cell marine batteries. They’re comparatively very affordable, and they’re durable enough to deal with repeated series of power drains and recharges. However, you’ll have to do some maintenance on them such as topping them off with water. They also don’t last too long, as you’ll need to replace them within a year or two.

2. AGM

These letters refer to Absorbed Glass Mat as it’s made with a glass plate and a substance that’s similar to gel. You won’t have to add distilled water to these batteries as they’re completely enclosed.

They also last considerably longer than their wet-cell counterparts, as they can go for 3 to 4 years. Because of all these superior features, they’re also typically twice as expensive as the wet-cell batteries.

3. Lithium-ion

You’ve probably heard of these types of batteries for smartphones, but you also have bigger ones that can help power trolling motors. These batteries are considered the cream of the crop because they’re so durable.

If you make sure to maintain them at a temperature of under 105 degrees, they can last for a full decade. However, they’re also extremely expensive.

This refers to amp hours and it indicates the amount of amps the battery draws in an hour. Basically, it tells you how long a battery will generally last with a single charge. At slow speeds, a 35Ah battery can last about 7 hours while a 100Ah battery can go for 20 hours.

Obviously, you’re not going to go at slow speeds all the time. You may have other gadgets besides your motor which draws power, and of course you can set a series of 12V batteries for your trolling motor for more power. But the general rule remains: the higher the Ah, the longer the battery lasts for a single charge.

Lifespan

We’ve already covered this topic with the types of batteries, with wet-cell batteries not lasting for a couple of years, AGM batteries lasting twice as long as the wet-cell batteries, and with the lithium-ion lasting for a decade. But even with 2 different batteries of the same type, one can last longer than others.

Here you really need to check out customer reviews so you can get a real idea of how long a particular battery will last. Also, you should check the warranty as well. Longer warranties tend to indicate a longer lifespan.

Vibration Resistance and Durability

Fishing boats may travel over choppy waters, and the jarring vibrations may bother your battery. However, some batteries are more able to withstand these vibrations than others. There are also other features that boost durability. Some are spill-proof, while others are shock-resistant.

Size

Not everyone has a big boat that won’t mind the use of a large battery. But smaller boats may be weighed down by bigger and heavier batteries. So if you have a small boat, you may want to limit the weight to less than 40 pounds.

Some batteries may indicate their group size, but most of the time the dimensions are explicitly stated anyway.

Convenience and Ease of Use

You will have to install the battery on your boat, and you should check reviews to see how easy that is for particular batteries. Some batteries are mountable at any position.

You should also check what kind of maintenance you need to do for the battery. Some of these things, however, are maintenance-free.

Versatility

Some batteries are just for starting the motor, while others help power onboard gadgets. The versatility of the battery may also refer to how you can use it besides on a boat. Some of these trolling motor batteries can also be used for RVs, motorcycles, scooters, jet skis, and perhaps even for alarms and wheelchairs.

Final Word

It’s easy enough to overlook the battery when you’re on a boat, and some people are under the mistaken impression that one battery is just like another. It only takes a single time to get stuck in the middle of the lake before you realize that your choice of battery is important. So choose wisely!
