Things to Consider When Buying Trolling Motor Batteries

Here’s what you need to consider when buying batteries:

Recharging

To understand its reserve capacity as a matter of priority over time, it is always necessary to check the current battery.

The reserve capacity is a very crucial rating for any battery. The measurement takes place in minutes. Once the voltage drops below 10.5V from 25 amps at 80 degrees Fahrenheit, that is the battery’s reserve capacity.

Some smart chargers enable you to adjust the charging speed accordingly. If your trolling battery charger is considered a smart charger, you may need to vary your speed.

Before starting the business, read the manual of the manufacturer carefully. The last thing you would like to do is cause a fire outbreak or damage your battery prematurely.

Size

The larger the battery size of deep trolling motors, the longer the battery will last. Do you want your battery to run longer? Check the battery’s amp hour rating (Ah) and the amperage draw. 

However, a 35 amp-hour or 70 amp-hour battery is enough if you’re mainly looking for a kayak. Your battery life will last depending on your amp hours.

Type

There are different types of batteries that are recommended for use with trolling motors.

Dual-purpose batteries are a combination of starting and deep cycle. These batteries work perfectly for small boats, short trips, or different uses. However, they’re not the best choice to run a quality trolling motor.

The deep cycle battery is designed to discharge smaller current quantities over a longer period. There are two deep cycle batteries:

Lead Acid Wet Cell battery

Because of the highly frequent draining and recharging associated with power operations, Lead Acid batteries are the cheapest option. The sealed Lead Acid battery costs less than $100 but is more prone to spillage and vibrations.

Wet cell batteries are a mix of water and sulfuric acid, which means that the cells and lead plates in the battery are either flooded or submerged into electrolyte fluid.

AGM Battery

AGM stands for Absorbed Glass Mat. This type of battery is completely sealed with a longer life of the battery. The internal resistance of AGM batteries is also lower.

Group size types are not battery types, but they’re considered battery families – the larger and stronger the battery, the higher the number.

  • Group size 24 is your most frequent cranking batteries, double-use batteries, and small deep cycle batteries. Around 11 x 7 x 9 inches of group 2 batteries are measured.
  • Group size 27 is more common for a deep cycle battery. 12 x 7 x 9 inches or larger.
  • Group size 31 is the last battery group. It is about 13 x 7.25 x 9.25 inches which are considered too large batteries.

Lifespan

Charging the battery with a trolling motor may be damaging if you do not use a deep cycle battery.

Choosing a high-quality, Lead-acid AGM battery with long service life and is considered a maintenance-free battery would be best. This is the best choice if you don’t want to buy batteries every year.

Durability

Please note any warranty included in purchasing the trolling motor battery. This should indicate the minimum time the battery should last. Contact the manufacturer right away if it does not last that long.

Voltage

According to powerboat manufacturers, trolling boats 14 to 16 meters long should be equipped with a 12-volt battery.

A 24 or 36-volt motor is needed for longer boats. Each trolling motor will be fitted with a 12v AGM deep cycle battery, with low hours of power supply over a long time.

Brand

Purchasing the best brand for motor batteries can be tricky, but fellow anglers are hyping some brands.

Basic Batteries

The Battery Mighty Max is a standard solution for anglers on a budget. However, don’t expect that Mighty Max will last really long.

Interstate Batteries

Interstate is a good quality brand that has been around since 1952. Some batteries are open-cell batteries that require fluid upgrades at a low level.

Centennial Batteries

About the same time as Interstate, Centennial originated in 1955. Centennial’s main difference from Interstate is that its batteries are closed – no liquids or tapers have to be checked. More reliable but pricier.

Optima Batteries

A remarkable feature of the optima battery is that they don’t even have fluid. Optima uses a fibrous component that allows the battery to operate even though it is punctured.

Weight

YouTube video

Most anglers won’t like carrying trolling motor batteries by hand. If your battery is bigger and heavier, there will be less room left for you and your fishing gear. 

Any common deep cycle battery may vary between 60 and 70 pounds. And by choosing the lithium-ion trolling motor battery, you can reduce the weight but only at a higher price.


Conclusion

Don’t skimp on your trolling motor battery. You might think that you’ll save some money by going with a cheaper battery, but you’re using it as your transportation over water. 

This means if the battery dies, you’re in a dangerous situation. Spend a couple more dollars upfront or risk the anguish of calling for a tow boat or spending hours paddling into shore.
