What makes a good trolling boat battery?

Trolling Motor Battery

When buying a trolling boat battery you need to make sure you are getting the best value for money, and a battery that is going to last you long enough. Running out of juice before you are finished fishing is shall we say, less than ideal. But what makes a good trolling boat battery? This article answers that in detail and much more:

Dual-purpose or deep cycle:

When picking a battery you need one capable of lasting the entire time you are out there. You cant use your boat starter battery, you will need a separate one just for the trolling motor. The reason dual purpose or deep cycle batteries are so ideal is that they are constantly slowly releasing energy over time, giving you long very periods of small amounts of power. If you were to use your boat’s normal starter battery, you could potentially blow your trolling motor by hitting it with a large amount of power all at once. A normal starter battery is designed to give a huge surge of power at once to start the engine, not maintain a steady stream, which is not what you are looking for.

Amperage per hour:

The higher your amperage per hour, the longer the battery will last before you need to swap it out. That means you can get away with buying, and bringing with you, fewer batteries. If you get the best amperage per hour you can, you may only need to bring one or two batteries, not 3. The optimal amperage per hour is approximately 125. One battery is normally enough if you are always running at low amperage. However, if you keep switching between high and low amperage though you will need two. One battery with an amperage of 125 could last all day if you run it on a low amperage, conversely, it could only last 2-3 hours if you keep switching to high.

Your batteries need to match your motor:

This might seem obvious, but you need to buy batteries that suit your motor. If you are using a 36v trolling motor, you might need to buy 3 12v trolling batteries. This is something to keep in mind. Not all motor/battery combinations will work together. Additionally, you shouldn’t be mixing brands of batteries, old batteries with new ones, or leaving one dead one in with 2 new ones. It might run for a while, but it could suddenly die with no warning.

Modern is always better:

Modern is always better is not a rule that applies to everything in life, but it always applies to batteries. There is no use getting sentimental about old brands, always try to use the latest and greatest batteries available. Newer batteries are better insulated and no longer require any real maintenance. They may cost more, but they are far superior.

Conclusion:

Hopefully, this article has given you some insight into what you should keep in mind when purchasing new trolling batteries. If you stick to guidelines this article laid out you should do just fine.
