10 Best Trolling Motor Batteries: Top AGM & Flooded Options

One of the most important pieces of equipment on your fishing boat is your batteries. Marine batteries can be an expense, but it’s not an area anglers should look to scrimp. Without quality trolling motor batteries, you can find yourself out of power at an inopportune time.

Nobody likes having to end their fishing day early due to dead trolling motor batteries. The good news is that today’s AGM trolling motor batteries are better than ever, with more capacity and less maintenance. Since AGM batteries are fully sealed, they can be purchased online and that will be the focus of this guide.

7 Things You Must Know Before Buying Trolling Motor Batteries

Even though batteries may seem like a simple and straightforward purchase; if you want to find the perfect one for you and your boat – there are a few things you should know. In this article, we’re going to cover all the critical factors that make a great trolling battery.

1. Sealed AGM vs. Wet Cell Lead Acid

Lead acid batteries are what you get used to hearing about. These use an electrolyte (usually water) to flood the lead plates, and as a result are very heavy. These batteries also require maintenance because you have to monitor the fluid levels and check for corrosion.

These batteries can be known to have vibration problems which reduce the overall life of the battery. All in all, lead-acid batteries are the norm, but they tend to have a shorter life compared to AGM style marine batteries.

2. What Size Battery for Trolling Motor?

Your trolling motor determines what size battery you need. It’s important to know what group size battery you need. If you do not have the right battery, you may not have enough power to turn the motor over, and you could find yourself stuck out on the water.

For good run-time, you want to have a group 24 battery that gives you 70-85 amps per hour at 12 volts. This battery works well for smaller boats.

For better run-time, you want to have a group 27 battery that gives you 85-110 amps per hour at 12 volts. This battery works better for bass boats.

For the best run-time, you want to have a group 31 battery that gives you 95-125 amps per hour at 12 volts. This battery works great for larger bass boats.

3. Get Enough Reserve Capacity

The amount of reserve amp draw is an essential factor to consider when choosing a battery. Reserve Capacity is the amount of time you have until the battery falls below the minimum voltage.

  • A 30-pound motor has a max draw of around 30 amps
  • A 40/45 pound motor has a max draw of around 42 amps
  • A 50/55 pound motor has a max draw of around 50 amps
  • A 70-pound motor has a max draw of 42 around amps
  • An 80-pound motor has a max draw of around 56 amps
  • A 101-pound motor has a max draw of around 46 amps
  • A 112-pound motor has a max draw of around 52 amps

4. Good Warranties are Important

Every manufacturer has a different kind of warranty. Some companies offer ten-year warranties, some provide lifetime warranties, and some only offer two or three months. You want to make sure to protect yourself and go for a battery with a decent warranty.

Of course, it’s important to look at the reviews and consider the average life of a battery vs. the warranty, but you should go for a battery with a good warranty.

5. Your Batteries are only as Good as Your Charger

When choosing a battery, it’s equally as important to select a good charger that is compatible with the battery you are using. Selecting an onboard charger that does not work well with your battery will not only cause you to get less time out of each use, but it’s also going to shorten the life cycle of your battery because you have to charge it more often.

If you are going to invest in a good battery, you should make sure to budget for an excellent charger to pair with it. This choice will ensure you get a good life out of your battery.

6. Name Brands vs. Off Brands

If you are undecided between a name brand battery or an off-brand, look at the reviews and get opinions from other people. Just because something does not come from a major manufacturer does not mean it is not as good.

If you look up an off-brand battery that is forty dollars cheaper than the name brand and it has fantastic reviews and a good warranty, I’d go for it.

7. Weight is Good, More Lead in the Core

The saying “the bigger, the better,” is right when it comes to marine batteries. More weight equals more lead in the core. More lead in the core means a longer run time and, in the end, – the longer you run your battery without charging the better chance you have of extending the life of the battery.

The only downside to a larger battery is carrying it around, but if you have a place to store your boat where the battery won’t be constantly exposed to the elements, you might be better off going for a larger battery.

Trolling Motor Battery FAQ

How many seasons of use can I get from an AGM battery?

This varies from battery to battery. Some people claim to be able to get as many as 10 years from one AGM battery, whereas others state only getting 2 or 3 years. It depends a lot on the individual battery. Another big factor that determines how many seasons you get from your AGM battery is the charger you use. If you invest in a great charger that is recommended by the battery manufacturer you have a higher chance of getting a longer life cycle out of your battery.

Why are Deep Cycle batteries best for Trolling Motors?

Deep cycle batteries are designed to discharge their power over a long gradual period of time. This is perfect for trolling motors because you may be out on the water for 8 or more hours. For this to happen using a rechargeable battery, you need something that is going to last a large amount of time. Regular batteries will exhaust all their power too quickly whereas deep cycle batteries will ensure you do not get stranded on the water.

How many amps do trolling motors draw?

It depends on the battery, but it typically ranges from 30 – 116 depending on the size and voltage of your battery.

How long can a trolling motor run on a deep cycle battery?

The larger your battery the longer it runs. Typically, for every 25 amps of battery power, you get 4 hours of running time.

What kind of charger do I need for AGM trolling motor batteries?

Every manufacturer recommends a specific charger but its most important to have a charger that has enough amperage and is compatible with an ABM battery. It’s always best to take the recommendation from the manufacturer though. This helps to extend the life of your battery and give you an overall better experience.

How important is a Battery Warranty?

Battery warranties are important because you want to make sure you are covered in the event that you need to be. More important than warranties though, are user reviews. Be sure to do your research ahead of time before making a purchase. Some companies offer warranties as long as 5 years and others only offer a few months. If the battery has good reviews and a short warranty, that may mean the quality of the battery is good and the company is confident in that.

How do I find what Group Size my Old Batteries are?

Often times you can find this on the battery or the manual if you still have it. A quick good search should also reveal a better way to find it on your specific battery.

Are AGM batteries worth the price over Wet Cell?

If you are looking for a low maintenance battery with a longer life cycle than a wet cell, then yes. AGM batteries are going to cause you fewer headaches over the long term. It’s definitely an investment in peace of mind.
