Can a trolling motor battery get wet?

A trolling motor battery should not get wet for best performance, power, and safety.

Getting out of your home for a trip especially in your boats is the best and even the awesome feeling. It diverts you from the daily burden and makes you feel amazing in the calm water. The surrounding is not less than a heaven for sure. You are really going to live a trip out in your boat. But that’s not fair thinking just about your betterment because the boat in which you are going also must be in a better condition to fulfill your desires. So here we will be going to an important aspect related to the motor of your boat. 

Every part of your boat is equally responsible for the proper functioning of the boat. But still the major portion is its motor and its maintenance. And this is from where you must also consider the battery used in the motor too. Since the trolling motor’s performances are all dependent on the well being of the battery. Have you ever thought about whether they can get wet or not because marine batteries are designed to be used in water and are water-resistant? 

The moisture associated with the terminal side may be one of the reasons for the battery getting wet. You must be aware of the vibrations issue of the batteries. Although great efforts are made to keep the battery isolated in the case without movement but still that vibration issue can be the reason due to which the water can drop into this area.

This is why make sure you keep the water away from the top side of the battery because the sensitive terminals reside in this region which can create power issues. If such an issue is faced then probably you must keep some points in consideration such as if the water drips inside the terminals or such puddles are formed between them or if the current runs between them, etc. 


The next possible way in which the battery can get wet is through a submerged base in water. This all deals up with the plastic base. Although plastic housing is just to be used as insulation it can also be the reason. Whatever water amount that gets stored is generally saltwater in which salt molecules are present which will ease the current flow and remember water around any electrically charged particle is not suitable.

You might not be known to this way of getting the battery wet because these are the secret leak areas. You may not even realize these hidden areas which can secretly deteriorate the working of the motor by making it wet. 

You also should take care of the wiring and should keep it safe so that it won’t come in contact with water. 

You must know the difference between using a motor in the freshwater as well as in the saltwater. The freshwater if continued with your motor can break down the battery with rust and slow discharge rates. But still, if your battery is submerged in the freshwater you still have to do the same solutions as done in the saltwater. Just try up the entire pack


So no matter how strongly your trolling motor battery is designed to oppose the water effect, it can get wet. So, make sure you are properly indulged with the maintenance and repair of the battery. To help you with the same here are some tips that would be really useful for securing your battery.

  • Make sure you apply a dielectric grease on the terminals.
  • The batteries that require liquid must be filled with the appropriate amount of distilled water.
  • The positive terminal must be installed with a cover.

The given tips will possibly help you to protect your trolling motor battery from getting wet and many other problems as well. So, never be in the myth that your battery is not prone to getting wet just because it is a marine battery. Moreover, also keep other points into consideration for the durability of your battery and protect it from other damages. Also, do make sure you are recharging it on time.
