Buyer’s Guide

Choosing the right battery can be difficult. To make it easier we have prepared a buyer’s guide that will help you make an educated decision.

Battery Size

Battery size is fairly important as the relation between the performance of a battery and its size is fairly proportional. Obviously, a larger battery will work longer hours, but larger batteries are not very suitable for kayaks or canoes. However, batteries that do suit them are comparatively smaller but not as lasting.

Voltage

Generally, 12 Volts or 24 Volts batteries are preferred for trolling motors. It depends on the individual requirement of every motor. Before deciding on buying a battery consider the voltage requirements of your trolling motor. Once you are aware of the requirements you can easily choose the right battery with the right voltage. 

Peak Power Draw

Just like the voltage, peak power draw is also motor specific and depends upon the type of trolling moto being used. Most motors have thirty amps to fifty amps peak draw however, this is not a general setting and thus you will need to know your motor and its draw before deciding on a battery.

Run Time

Run time is one of the most, if not the most, crucial aspects of choosing a battery. Basically, as we said in the beginning. Larger batteries provide longer usage and thus you need to know your requirements to choose the best battery for your motor. There are no specifications or generalizations when it comes to run time, only what you prefer is what matters.

Car or Starting Battery

This a common and the most dangerous misconception when it comes to batteries for trolling motors. People often assume the same batteries can be used for cars and boats alike. However, this is not true and can result in the loss of your motor entirely.

Trolling motors have separate batteries that require a constant flow of power throughout the day and are nowhere similar to car batteries. Car batteries, if used can cause some serious damage to your motors.

FAQs

1. How long will a battery last per charge?

The lifetime of a battery charge depends upon what kind of a battery it is and how long does it stay recharged. However, as a rule of thumb, the lifetime of a battery’s charge is relative to its usage and size. If it is a larger battery it will last relatively longer without recharging as compared to its smaller peers.

2. How long does it take to charge a trolling motor battery?

The time it takes to charge a motor battery depends upon the amperes supported by the charger. The higher the amps the quickly it gets charged. Usually, AGM or deep cycle batteries require longer hours to get fully charged as compared to Lithium-ion based batteries.

3. How many seasons of use can I get from an AGM battery?

The performance or lifetime of an AGM battery can vary based on several factors. The highest reported seasons for AGM batteries have been almost ten years whereas the lowest being almost two to three years. The right charger can increase the lifetime of a battery whereas a wrong charger can completely ruin it.

4. What kind of charger do I need for AGM trolling motor batteries?

All manufacturers recommend a charger that is compatible with their batteries and has the required amperage for the battery to function properly. Such recommendations should be taken seriously and acted upon.

5. How do I find what Group Size is my Old Batteries are?

Mostly, the group sized is mentioned on the battery or the manual. However, if you still can’t find it we recommend a quick google search with your battery’s credentials.

6. Are AGM batteries worth the price over Wet Cell?

Yes, we would say so because not only AGM batteries require less investment, they also have a longer life. The comfort and ease with an AGM battery are unmatchable and thus, its definitely worth the price.

7. Do I need any hardware or connectors to use a new battery?

You will not need new hardware or connectors if you choose the battery that matches with your trolling motor. But even you did end up buying a motor that entirely does not match then conversion kits are easily available, which will allow you to try out different terminal styles.
