Things To Consider While Buying a Good Trolling Motor Battery

There are several brands of trolling motor batteries out there with varying quality and dependability. To pick the best product for your boat, there are certain factors you should pay attention to.

Type of Battery

This is probably the most important consideration you need to make when choosing a battery for your trolling motor.

There are three main types of batteries for trolling motors – wet-cell, lithium-ion, and AGM batteries. Each of this type of battery has its own advantages and disadvantages.

The wet-cell batteries are usually the cheapest options, but they require a lot of maintenance and last for only one or two years.


When purchasing any product, it’s always advisable to go for a brand that has a warranty. This gives you the chance to get back your money or at least a replacement in the event the product doesn’t arrive whole or gets damaged after a few weeks of use.

Luckily, all the items on the list come with a decent warranty which guarantees their quality. But of course, you may still want to skim over reviews left by other people who have used the product.

Charger Compatibility

Whatever you do, you must always remember that your batteries are only as good as the charger you use for charging them. A bad charger or one that is not compatible with your batteries will only make the battery look as bad. And you may have to replace the battery too soon due to frequent charging.

So while selecting a battery, also pay attention to the charger you are going to use for it. If you already have charger onboard, then you might want to select a battery that is compatible with it.

If not, then you should also consider investing in an excellent charger that will work well with your device.

Weight of the Battery

Another important consideration to make when choosing a trolling motor battery is weight.

Except you are approaching your boat’s weight limit, it is generally recommended to go larger battery; usually, the bigger, the better. And the reason for this is quite simple – more weight directly translates to more lead in the battery core which means thebattery is going to run for a longer time without charging.

While this sounds cool, it might not always be convenient to carry a big battery around. Most of the batteries in the market weigh between 20-50 pounds.

For many anglers and kayakers, anything below 30 pounds is the deal. But again it all depends on your purpose and weight capacity.

Frequently Asked Questions

Lets quickly look at some of the questions customers usually ask when purchasing a trolling motor battery.

What kind of maintenance does my trolling battery needs?

To ensure a long lifespan and proper functioning, adequate maintenance of your battery is important. This doesn’t necessarily mean you should clean the device all the time.

Although most AGM batteries don’t need any kind of maintenance, you should also be mindful how you use them. Don’t overcharge the battery and try to keep dirt away from it.

It is also a good idea not to always use up your battery before charging. Using only 75-80% will help to extend the battery life.

Where is the best place to store my trolling batteries?

It’s best to store your battery in a cool location below normal room temperature. But make sure you don’t expose it to too much cold and avoid keeping old batteries together with new. Also, make sure you separate batteries of a different type.

How do I know when I have a bad battery?

To check for the state of your battery, you can use a multimeter. Make sure you change the battery once you notice any damage or else it can affect the trolling motor.

How do I know when my trolling motor battery is due for replacement?

This depends on the kind of battery cell you are using. But generally, when you notice that your trolling motor takes longer to start or if you have to charge the battery more often than normal, then it’s likely the cell is approaching its end. You may need to get a replacement at this point.

What kind of batteries is best for my trolling motor?

It is advisable to go for a deep cycle or marine battery with a rating of 12 volts and 50 Amp Hour.


Getting thebest trolling motor batteriesfor your boat is extremely important for a reliable trip on water. So don’t always be in a hurry to purchase a product just because it’s very cheap.

The truth is that your trolling motor is only as good as the battery you use for it. So to ensure you make a worthy investment, try and spend a little time in finding the perfect fit. Hopefully, our reviews are all you need to make that decision.
