The Best Trolling Motor Battery – Our Top 8 Picks

Best Trolling Motor BatteryThe most horrendous thing that can happen to any angler out there is when their trolling motor dies in the middle of their fishing trip.

Not only will it hamper your fishing experience, but it will keep you wondering how you can go back to shore. Finding the best trolling motor battery sometimes requires expertise and skill, just as you need specific strategies when fishing.

Though motor batteries can be quite expensive, some amazing products on the market today have found the balance between budget and quality.

You do not need to buy the cheapest or most expensive one. We want to find common ground where you get a trolling motor battery that works well and still stays within your budget range.

Two Types of Trolling Motor Battery

When purchasing a trolling motor battery, you need to know what the different types are. That way, you will have an idea of what suits your fishing needs better. The recommended batteries for trolling motors involve two types of deep-cycle 12V batteries.

For those unfamiliar with deep-cycle batteries, these batteries are made to discharge small amounts of current over an extended time.

However, these batteries also need frequent recharging. The two types of deep-cycle batteries recommended for trolling motors are lead-acid wet cells and AGM batteries.

So what are these batteries?

Lead Acid Wet Cell batteries are the most common and most affordable option for anglers. This type of battery has a lifespan of 1 to 2 ½ years. It often costs less than $100, so anglers on a tight budget may prefer this type. Unfortunately, lead-acid wet cell batteries require frequent maintenance. You may also experience vibration and spillage from time to time.

The other battery type is AGM. AGM stands for Absorbed Glass Matt. These batteries have a longer lifespan and last longer when fully charged since the batteries are sealed. You can use an AGM battery for three to four years.

The only downside of this battery is that it is way more expensive than the lead-acid wet cell batteries. But if you have the budget, these batteries are still worth investing in since they last longer and perform better. They are also 100% maintenance-free, so you do not need to worry about anything at all.

Lithium Ion Battery: A Premium Choice

If budget is the least of your worries, then try a lithium ion battery. This battery upholds the highest rank when it comes to the best trolling motor battery.

Lithium batteries are more superior to lead-acid wet cells and AGM batteries. They also have a longer life span and do not require maintenance too.

Lithium batteries are usually lightweight and can hold constant power with fast charging time. They are also temperature-resistant and have an 80% rated capacity for more than 2000 miles. A lithium battery is the best choice if you have enough money to spend.

Things You Need to Consider

Each person has different needs. One battery may work well for this person but not for the other. That is because each battery also has its own specifications and features. No batteries are the same, even if it seems that they have similar traits. Before buying the best trolling motor battery, here are some of the things you need to consider.


As you can see from the above list, most trolling batteries have 12V. That means they can power motors and other stuff on the boat that is 12V. Some large trolling motors may require 24V.

When this happens, you can get two 12V batteries to power it up. Before purchasing a battery, check the voltage of your trolling motor first so that you’ll know how many batteries to buy.


Are you willing to do some maintenance work on the battery? If yes, how much effort are you willing to put into it?

Maintenance is an important aspect for every battery unless otherwise stated as maintenance-free. Lead-acid wet cell batteries require maintenance. You need to occasionally inspect it for signs of corrosion. You also have to clean it and add filtered water from time to time.

On the other hand, AGM batteries do not require any maintenance at all. Lithium batteries may or may not require maintenance, depending on the manufacturer’s guide.

Maintenance-free batteries are very tempting to have, considering that they can save you a lot of time and effort. The downside, however, is their expensive price tag.

Amp Hour Rating

Each battery has different amp ratings. So, you need to be very mindful of this. The higher the amp rating, the longer the battery can last.


Talking about the price tag, you need to consider your budget. How much are you willing to cash out for a piece of battery?

Regardless of what you can afford, you can still get the best trolling motor battery within your price range. If you have more to spare, investing in AGM or lithium batteries is highly recommended.

You do not need to worry about maintenance and spills. Such batteries also have a long lifespan, so you can actually save in the long run.

But fret not if you are on a tight budget. You can still get a quality lead-acid wet cell battery for an affordable price. All you need to do is to be patient and meticulous when keeping it in shape.

Recharging Time

Recharging time is often overlooked, but this is one of the most essential considerations. AGM provides the fastest charging time. Fast charging allows you to enjoy more fishing time since you do not need to wait for hours on end until the battery becomes fully charged.

Battery Type

Of course, you need to know which one suits you best and when it comes to different battery types. You now have a good idea of the basics for each type.

Each type has its own pros and cons, from budget to maintenance to other key features. Make a checklist about the pros and cons, and see which among the battery types you prefer and fit your budget.


Another important thing to consider before buying the best trolling motor battery is the size. Batteries come in different sizes, and you need to make sure that the battery you want fits on your boat.

Though most batteries can be installed in any direction, it is still customary to get the right battery size for your boat.

A larger boat requires a bigger battery size as it contains more power. Conversely, a smaller boat can do well with a compact size battery.

However, if you have enough space to spare for a larger battery on your small boat, you can also make use of a larger one. That way, you can be assured that the battery won’t die down in the middle of fishing.


Batteries are drained faster when the maximum weight capacity of the boat is reached. You need to choose a lightweight battery to counteract the weight the boat has to carry.

If you have a small boat or have to carry the battery to and from the boat most of the time, do not go for heavy batteries. But if you have a large boat, a heavy battery may be more efficient and reliable in providing the power that the boat needs.


Fishing is a nice pastime. It can get annoying when you have to stop fishing to recharge the battery. So, choose the best trolling motor battery wisely.

With the different batteries we provided, you can narrow down your choices and pick the best one. Just be sure to keep all our considerations in mind as you narrow down your choices for the best trolling motor battery.
