Sure, it’s a little bit heavier than most lithium models, but  trolling motor battery not so much as to be a game-changer. Furthermore, at only a fraction of the price of most other batteries it’s a true bargain. Interstates are one of the most common and widely-available batteries because they provide reliable power and also because of their price. For the casual angler, they’re a no-brainer, and even for the seasoned kayak tournament pro they’re a viable choice. So if you plan on going on a fishing excursion that is going to take hours, then these would be the best batteries to use.

Each group size number—24, 27, or 31—correlates to specific dimensions. This is important to know as many boats have a battery compartment designed to hold a certain size battery, so you want to choose one that will fit the specifications of your vessel. The famous blue-top battery uses proprietary Spiralcell and Pureflow construction to improve its performance. Spiralcell uses stronger links between the battery’s cells to increase vibration resistance.

 

A lead-acid wet cell battery typically lasts between 2 and 4 years with proper maintenance. AGM and lithium batteries may last longer, with some lithium batteries boasting a lifespan of up to 10 years or more. Whether you’re a seasoned angler or a first-time boat owner, this guide will provide you with all the information you need to select the right trolling motor battery for your needs.

 

The battery weighs 49.5 pounds, and its dimensions are 13.25 x 11 x 9.5 inches. One of its specialties is the M8 terminal, which has exceptional conductivity. Other than that, it also has durable handles for easy mobility and access or to carry it around. This uses an (AGM) technology with a regulated design that doesn’t allow any leaking and is maintenance-free.

Increased power allows you to have a cleaner image, especially on live imaging and forward-facing technologies. The battery is rated at 1,500 cold cranking amps, which is not really a thing in lithium power, but it’s more than enough to start an outboard. What you actually need to start an outboard is so many continuous amps for a number of seconds.

 

It’s also heavy, but the built-in handle means it’s easy to carry. All-in-all, this is a powerful, versatile battery that should last many years. This isn’t the heaviest battery but, at 37lbs, it’s heavy enough that the flip-up handle is really useful.

You get the same rated capacity even when discharging them very fast. This would normally compare with a lead-acid battery that is rated at 160Ah. Most lithium batteries can be discharged down to 10-20% SoC (State of Charge). Lithium batteries are lighter, offer better performance, have longer run times, and last much longer than traditional lead-acid batteries.

 

So if you find the motor to be very weak after a day’s use or against the current, upgrading the trolling motor battery group 27 to group 31 could be helpful. They’re powerful and reliable, even in very hot or icy environments. Still, if you anticipate using your trolling motor on rough water, a leakproof AGM or lithium-ion battery would be a better choice. This battery is a great trolling motor option if you use a tandem fishing kayak or a small boat.

 

These are the abbreviations that matter when you’re looking for battery specs. Any others you see will be related to the product model, and don’t have a bearing on the battery performance (except perhaps for taking manufacturing quality into account). Ampere hours will typically range from 35 – 100 in deep cycle batteries, but can be found in lower and higher hours as well. The higher number meaning the battery can provide more energy (and will be bigger too).

 

Note that car battery needs to be inside an enclosed, protected environment, such as under the hood of a car. They’re not designed to be in the open, taking on extra vibrations. It’s important to note that the actual capacity of a battery may vary on various factors, such as temperature, discharge rate, and age. Consider these factors and follow the battery maintenance tips when making a selection.

 

The right trolling motor battery for you depends on a variety of factors, like your budget and the type of boat you own. There are wet cell batteries, advanced glass mat (AGM) and lithium models. All have their advantages and disadvantages, along with differing price points. There are four models to meet anglers’ particular power needs and space limitations, but all of them come with the same proven reliability. They’re also widely available, so if you do run into an issue an exchange or replacement should not be a problem—but their trouble-free design makes that unlikely. Put them in the boat and prepare to run your trolling motor as long as you can stand to be out.
