A trolling motor battery is a piece of equipment that you definitely need whether you spend a lot of time in the water, or you are looking for a backup motor in case the boat engine fails (No one wants to be in the water without reliable power!) or even as a general backup power supply.

AGM vs Wet Cell Trolling Motor Batteries

Wet cell batteries are traditional, affordable batteries that handle frequent charging without being damaged. These batteries require maintenance by adding distilled water and are susceptible to corrosion and leakage since they are not sealed.

Absorbed Glass Mat batteries (AGM) on the other hand are sealed batteries that charge much faster than the wet cell batteries and last longer. They are more costly than wet cell batteries, but considering their durability and vibration resistance, they are usually worth it.

7 Things to Consider When Selecting Your Trolling Motor Battery

1.    Ampere Hours

This refers to the number of amps that can be discharged in a certain amount of time. You need to identify how many amps your motor needs to power it. The bigger your boat is the more ampere-hours it will need.

2.    Size

The size of your motor determines the battery size. A battery that is too big for your motor,  is likely to weigh it down, while a battery that is too small won’t be sufficient to power up your motor. You can easily find your motor requirements in its catalog.

3.    Vibration and shockproof

Water vessels are likely to face currents and vibrations so keep that in mind. You need a  vibration resistant battery or else there is a risk of damage. A sealed, shock resistant battery is your best option.

4.    Ease of use

Since you will be installing the battery, it is key that you choose a battery that is not complicated to install.

5.    Versatility

Buying a battery that you can use for many functions rather than one, means you get a lot of bang for your buck. 

6.    Design

Most trolling motor batteries nowadays are designed in a sealed, lightweight compact design allowing you to mount it in any position you like.

7.    Lifespan

We can’t give a precise number as to how many years a battery would last, because that depends on a variety of factors such as the material used, the temperature in which it operates and usage rate. Generally speaking an AGM battery can last 2 to 3 times as long as a wet cell battery, on average.

Trolling Motor Battery FAQ

1.    How should I store my battery?

Store your batteries in a dark room and separate different types of batteries.

2.    How do I maintain my battery?

Avoid overcharging your battery if you want it to last longer and make sure you never drain it fully. Aim to only consumer 75% of its charge before recharging it again. If it’s a wet cell battery, be sure to fill it with distilled water occasionally.

3.    Do I clean my battery?

Not really! All you need to do is wipe off any dust or grime on your battery.

4.    Which charger should I use?

If you want your battery to perform well, you need to make sure you use a compatible charger and it’s best to use one recommended by the battery manufacturer.
