If you thought owning a battery for your trolling motor meant spending a fortune, this product will prove you wrong. For a reasonable price, you can get this AGM battery that provides reliable and consistent power. The impressive 100Ah rating is proof of this. It’s not surprising why we consider this model as the best battery for trolling motor.
This unit is both shock and vibration resistant, which contributes to its overall lifespan.
Because this is an AGM type of battery, it’s spill-proof. This means you can expect zero acid leaks so it maintains a charge for longer. Also, this makes it a maintenance free unit.
The battery arrives fully charged and ready for use straight out of the box. Installation of the unit is a relatively hassle free process. It can be mounted in any position. We’ll have to warn you that weighing over 60lb, it’s not the lightest model on the market.
It’s a rechargeable battery so be sure to charge it after every use. Either that or it might not power your trolling motor for long during your next fishing adventure.
The 170 reserve capacity is a nice touch. You’ll have more than enough reserve power to keep your boat moving if the alternator fails.
The major downside to an AGM battery is that it’s prone to overcharging which may prematurely damage the unit. It’s not surprising that most users have complained that their batteries died after a few months. Always make sure you use the unit as recommended by the manufacturer to avoid this.

What impressed us with this product is its rugged construction. This marine battery for trolling motor is made up of high quality material which contributes to the unit’s durability. You’ll appreciate that the manufacturer covered the battery in a high-impact resistant case. If your boat hits a few bumps along the way, the impact will in no way damage the battery.

Weighing just under 40lb, it’s slightly lighter than the model reviewed earlier.
Best of all, you don’t have to part with too much money thanks to the reasonable price tag.
However we’re concerned that the amp rating may be slightly lower than what the manufacturer claims. Testing this model on a Battery Life Tester reveals that the unit produces 12amps per hour as opposed to 18. As such it may have a lower life expectancy than expected.

This is a rechargeable battery that can be mounted in any position, so installation of this unit is a breeze. Note however that while the manufacturer includes screws for installation, they don’t include the mounting harness. You’ll have to make a separate purchase.

Did you find the best battery for trolling motor reviews helpful? Are you ready to make your pick or are you still uncertain? If you still need further clarity, we’re positive that going through this buying guide will help put things into perspective. Included in this section is information you need to know when picking a marine battery to make your selection process easier. We’ve also answered a few questions you may have regarding marine batteries.
Let’s start by outlining the key features you need to keep your eyes peeled for when comparing one model to the next. Don’t be scared by the technical terms and various numbers under each model; allow us to clarify what these mean for you.
When deciding on a battery for your trolling motor, you have three options. AGM, Lead Acid Wet Cell and Gel batteries. Each type influences durability, price and ease of maintenance as we’ll explain shortly:
Pay attention to the amperage rating stated on the battery because it largely determines the unit’s overall performance. This makes it one of the most important metrics to consider before making your final purchase.
Manufacturers rate battery performance in amp hours. The number displayed on the unit is an indication of how much electricity the battery can store. In short, this rating indicates how long the battery in question will power your trolling motor for. The higher the amp rating, the longer the battery can power your boat and other appliances.
Small batteries usually have an amp rating of between 25 and 50Ah. Do you prefer a larger battery? It’ll have a rating of up to 100Ah. The Universal UB121000 model is one such example that has a 100Ah rating on our list.
Do you live in a cold climate area? Then you’re very much aware of the hassle involved when trying to start your boat’s engine during such weather conditions. The last thing you need is to spend hours trying to crank up your boat’s engine before it actually starts. This is why you need to consider the battery’s cold cranking amp (CCA) before you buy it.
This rating signifies the battery’s ability to start your boat’s engine in cold temperatures.
So should it be high or low? Opt for a battery with a higher CCA rating because that means it has greater starting power and won’t give you any problems.
With a 750 CCA rating, the Optima 8016-103 D34M is one of the few products on our list that’s designed to power up your boat effortlessly in cold weather.
Much like cars, trolling motors are available in varying makes and models & have different engine types. As such, each trolling motor will have different physical dimensions and terminal locations. You want a battery size that matches those exact specifications.
How will you ascertain this?
All marine batteries are assigned numbers and letters according to their group size by the Battery Council International (BCI). Some boats can accommodate batteries from different group sizes.
But there’s no need for guesswork, simply pick the group size recommended for use on your trolling motor as per the manufacturer’s specifications.
To avoid disappointment, you must ultimately ensure that the battery you pick fits inside your boat before making any purchases.
It’s difficult to determine the overall lifespan of a battery because this is dependent on many factors. What’s the battery design? How are you using, maintaining and storing the battery? What temperature conditions will the battery be operating under?
As previously stated, Gel batteries last very long; between 10 and 20 years. AGM batteries last approximately four to eight years. And Wet Cell batteries will last at least two years.
Maintenance and storage of your battery determine how long it’ll last. We’ll give you a few storage tips a little later in the article that you can incorporate to ensure that your battery lasts long.
Regardless of the type you pick, consider the warranty period covering the unit. This way you can take it in for repairs if you happen to experience any challenges with the unit. The VMAXTANKS VMAX V35-857 is one of the more durable models on our list and is designed to last between eight and ten years.
Some manufacturers add additional features onto their batteries. Granted, this may increase the product’s price, but certain extra features are worth paying for such as:
