For those who are fervid about trolling knows the fundamentality of having a dependable trolling motor. The better the batteries, the easier it is for you to move your boat at a slower yet your own pace. When the batteries die in the process, it is analogous to your own demise, with no option but to retreat to the shores. Battery life suffers beyond mechanical failure.

Due to their diverse size, the functionalities are different. Nevertheless, these five approaches are tailor-made to give your battery the much-needed energizers to function long term. 

ways to make your trolling motor batteries last longer

Way 1: Always Start Off With the Preparation

There is a saying that prep time is as essential as cook time. While this proverb is anonymous, the validity of it is real. The first way of an ideal preparation is inspection. There is no written formula for the number of ideal days to check on batteries, but the regular recommendation is on the weekly basis. When checking for batteries there are some aspects that needs to be catered of.

Batteries get damaged when cracked, bent and dinged. If you keep it at close proximity towards water the chances of getting damaged escalates tenfold. These are not the only aspect of awareness while undergoing battery preparation.

The shaft is another key metric for checking the batteries. If it’s filled with seaweeds and another fishing object, the batteries are prone to get cut off. To avoid such potential damages having needle nose pliers are lifesavers. The last method of preparation would involve, tightening all the screws before the operation. Otherwise, the end result is all doom and gloom.

Way 2: Healthy Cables Is Equivalent to Healthy Batteries

One of the smartest ideas to cleaning battery is to clean the essential components of it. Cables are one of them. When it comes to cables the first method involves checking whether all the cables are fresh or worn out. The next method involves ensuring that the cables are corrosion-free. Having a single connection that is not free from corrosion, indicates that the cables are dirty that will overburden the battery life. The common rule for batteries and cables is to always unplug while not in use.

 Cable protection goes beyond prior to operation. During the start there is one last precaution boat riders have to ensure: all the wiring needs to be wrapped and hidden inside the boat. The most common rules of physics involve water conducting electricity.

If the wires come close to the water the last sound you’ll ever be hearing in your life will be ‘Kaboom’. Lastly for maximum battery endurance always enable the deep cycle battery to charge at maximum. What happens if you don’t follow such rules? Not keeping the battery at 100 percent detriments the capacity to hold a full charge. This will cause a reduction in battery lifespan. 

Way 3: Having a Switch to Control Batteries Simultaneously

Boat owners come from all parts of the globe. This also includes places where there is little to no power source. If you are one of those unfortunate recipients having a switch control does wonders to the batteries. The switch has numerous options available for you. Firstly you get to choose which batteries you want to select: be it the starting batteries or trolling batteries. You can choose either one or both.

 Also, you have the luxury to choose isolation. Such an option allows variation that will offer you sufficient options to recharge and enhance battery life. This also enables you to have options to charge for longer durations, especially when making a speed of around 20 miles per hour.

Such option is complex therefore one must tread carefully when implementing it. Do not switch on all the batteries at a time when the motor is not properly functioning. Last thing to note is to start the motor from the starting battery if you want optimum results due to having too much wiring.

Way 4: Cleanliness Is a Virtue

Your trolling motor is susceptible to be filled with weeds while going on for fishing or a ride. Therefore it is simple common sense to clean the motor every time after the activity finishes. By not doing the simple yet basic requirements the debris in the battery will easily pile up to be more problematic.

There are ways to clean up such mess. With little use of water and specific solutions such mess can be avoided. After implementing it the next step involves the application of silicon spray and wiping it with a dry cloth. Such an approach ensures the batteries will not be in contact with water. 

Way 5: Invest in Better Charging

Battery for any motor is an asset, therefore replacing it will be utmost difficult of an objective to attain. Therefore buying a charger that compliments battery is highly essential in order to preserve and enhance the durability of the battery. For the starters avoid faster charging.

The best mode of charging in any motor batteries is using trickle charger. Such a category of charging allows transferring of electricity from a power source in a slow manner. Unlike fast charging, batteries hold the power for much longer time with the slower method.

All you need is an electric plug and two jumper cables then you are good to go. However, when going through charging do ensure that all the screws and bolts are tightened to perfection.


How Long Should Be Trolling Motor Battery Last?

Ans: 6-8 hours appears to be sensible with a more established motor. Battery bunch size could assume a part in life yet on a 12v more seasoned force drive a 24 to 27 gathering battery running between 6-8 hours is in accordance with where you can anticipate that yourself should be.

Would You Be Able to Utilize a Starting Battery for a Trolling Motor?

Ans: A starting battery ought not to be utilized for trolling motors or fueling machines. Marine Deep Cycle Batteries are intended to release gradually throughout an extensive stretch of time and to withstand a few hundred charging and releasing cycles.

Can You Run an Electric Trolling Motor Out of the Water?

Ans: The motor relies upon water for cooling so don’t allow it to run for extensive stretches of break of the water. The longest enduring batteries will be batteries that have the most noteworthy AHr (amp hour) rating.


Batteries in trolling motors are precious, maintaining it properly is one step above it. With proper regular service and guidelines not only the health will improve, but it will not compromise optimal performance that this will generate to your motors.
