They can last for as long as two years and they require regular maintenance. This type of battery cannot tolerate vibrations and are spillable.

Therefore, you should feel free to shop from other reputable companies out there provided you carry out a research of the product to ascertain its quality.


Some cheap trolling motor batteries can last for as short as six months while excellently designed batteries can last an average of four years.

For this reason, we suggest that you spend some time shopping around for batteries designed to last. Such batteries are vibration and shock resistant, non-spillable, and they can tolerate extreme temperature and humidity.

Reserve Capacity

Trolling motor batteries are not created equal. Some batteries can hold their charge for long while some can only hold a charge for a short duration. As such, if you love trolling for long, we suggest that you shop around for a battery with a good reserve capacity.

Maintenance Tips

Despite the fact that most trolling motor batteries can last an average of 3-4 years, only a few live up to the lifespan. This is because most people do not follow the maintenance guidelines suggested by the manufacturer.

Below are some of the maintenance tips that help you extend the battery’s life:

Keep Your Battery Charged

You should also use approved battery chargers since undersized chargers may take long to recharge the battery while oversized chargers may lead to overheating.

Boost Charge an Unused Battery

Boost charging should be done once a month for those living in warm climates. Those in cold climates can boost charge their battery once in two months.

Batteries should Never be Discharged below 80 Percent

Battery experts say that if you use a battery discharged below 80 percent, you are likely to be overworking it. Besides overworking it, you also speed sulfation, a factor that can reduce your battery’s lifespan.

How to Choosing the Right Marine Battery
