When you’re out on the water enjoying a nice day of fishing the last thing you want is for your day to be ruined by a dead battery.

It takes time to find the best fishing spot, but you can’t do that with a subpar battery that will die in the middle of your fishing trip. 

That is why it is important to ensure your boat is equipped with the best battery for trolling motor bass boats. After all, it is one of the most important pieces of equipment on your boat.

Not everybody considers the importance of a quality battery. Batteries are not usually the first thought because they are hidden inside the trolling motor.

If you don’t see it, you sometimes forget about it.

But, as the saying goes, it’s what’s on the inside that counts! Of course the look of your boat is important, but looks will not make things run smoothly.

Why not make sure it looks good and runs well?

All batteries are not created equally so we have put together some information to help you decide which one is best for your bass boat. 

Why is a good battery important? 

You can go out and buy any battery you want, but have you considered what you are getting out of that battery?

Did you know that you can use your boat’s battery to power more than just your motor?

If you find the right battery, it can work as a power source for other gadgets you might have on your boat. Why not get the most out of it?

Think about the life expectancy of the battery. A good battery will last for years.

If you go out and buy any old battery, you may only get a few months out of it.

That puts you at risk for getting stuck on the water with a dead battery. Nobody wants the hassle of that during a fishing trip. It’s all about that bass!

Kidding aside, batteries have come a long way. There isn’t a “one size fits all” battery for bass boats.

You have options to choose from so why not find a battery that will not cut your fishing adventures short?

It’s important to find a good battery for your boat because it will give you the peace of mind you need to enjoy your days on the water. 

So what do you need to look for in a good battery? 

What to look for in a good battery


There are a couple different types of common batteries you can choose from. The most common battery is the Lead Acid battery.

The lead acid battery has been around since the beginning of engines.

People that are on a budget will likely veer toward buying a lead acid battery, but it does not come without its faults.

Although it is the more budget friendly option, it is high maintenance and much more vulnerable to damage. Keep that in mind if you do choose to use a lead acid battery in your trolling motor. 

The other most common type of battery you can find is the AGM battery, or absorbed glass mat battery. This battery does not use acid so there is no risk of corrosion within the battery unlike with the lead acid battery.

The AGM battery is also more durable than the lead acid battery and can handle stronger impacts without sustaining a lot of damage.

Life expectancy of the AGM battery is higher than that of the lead acid battery. AGM batteries are overall better quality and worth the investment.


The size of the battery will depend on the size of your trolling motor. You need to know the group size your battery is in to find the right size for your trolling motor.

The group size depends on the dimensions of the battery.

Typically, the bigger the battery, the more power it puts out, but make sure the battery you choose fits well in your motor.

Amp Output/Hour

Before purchasing a battery, check the amp hour rating. How you plan to use it will depend on how many amp hours you need.

The amount of amp hours will contribute to how long your battery will last for a single use. For more detail on choosing a battery with the correct amp hour rating for your usage, check out this guide.


It is always great to have a warranty attached to anything you buy and since these batteries are an investment, it’s a good idea to make sure it comes with some kind of warranty.
