How to Choose theTrolling Motor Battery for 80 lb Thrust? (The Buying Guide)
When it comes to choosing the best deep cycle trolling motor battery, there’re a few things that you may need to consider. The type of battery, amperage hour rating, frequency of your shipping, size of the vessel are some of them.
I bring a detailed buying guide for you so that you can purchase the right marine battery for trolling motor once you go through it.
Amperage Hour Rating
Amperage hour rating is another important factor you should consider which largely depends on your driving patterns. A battery with a 125 amp hour rating should last more than a battery with a 100 amp hour rating.
Your driving pattern is important to consider because if you drive slowly, for example at 5 amps, a 100 amp hour battery will last for 20 hours. Again, if you run at a high speed with 50 amps, a 125 amp-hour rated battery even would last for 2.5 hours.
It is recommended to use at least a 100 amperage hour rating battery so that you get a significant fishing period.
Size & Weight of the Boat
As your boat has limited space and weight for the battery, you should get one that matches the size and weight of the vessel. Otherwise, your watercraft will lose its balance and you won’t be able to drive and fish efficiently.
Based on the size and amperage hour rating, Minn Kota batteries can be divided into three main groups. The higher the amperage rating, the longer will be its runtime. Also, cost and size increase accordingly.
| Battery Group Size | Battery Voltage | Amperage Hour Rating |
| 24 | 12 V | 70-85 |
| 27 | 12 V | 85-110 |
| 31 | 12 V | 95-125 |
Resistant to Vibration & Corrosion
Resistant to shocks and vibrations is one of the measures to determine the durability of the battery. A deep cycle battery for trolling motor is usually kept exposed and goes through lots of vibrations that may damage the battery.
AGM batteries are resistant to shocks and vibrations and hence are very durable to last long.
Again, corrosion is another headache that you don’t want to have. Because of the sealed containers, AGM Marine trolling motor batteriesare resistant to corrosion.
Best Trolling Motor Battery For 80 Lb. Thrust: My Honest Review
There’re are lots of marine batteries available on the market. However, not all of them are reliable for the job. In the trolling motor battery reviews, I bring some of the most reliable batteries for you so that you can purchase any one of them instantly without worrying much.
All the batteries are capable to charge a trolling motor that produces 80lb thrust. Batteries with a 12V voltage, significant capacity, and over 150 minutes of reserve capacity should be great for a trolling motor of 80 lbs. thrust.
