Benefits and Importance of Buying a Good Trolling Motor Battery

man installing trolling motor battery

Although everyone is limited by their own budget, and most boaters want to spend as little as possible on their trolling motor battery, it is important to understand the importance of buying a good trolling motor battery.

So, while there is certainly nothing wrong with choosing a battery that fits within your budget, you should be sure to select a high-quality model, which will work the way you need it to.

A few of the most important reasons to do so include:

  • You want to know that your battery will be ready to go every time you hit the water. If you purchase a sub-standard battery, you may get out on the water and find that your battery won’t power your trolling motor.
  • You want to ensure that the battery won’t pose any safety hazards. Poorly constructed batteries may become damaged, which can result in a cracked casing. This could cause skin-damaging battery acid to leak into your boat.
  • You don’t want to select a battery that may end up polluting your favorite lake. Leaking battery acid isn’t only a problem for your skin – it may also pollute your local waterways. Accordingly, it is imperative that you select a battery that is durable and well-made.
  • You don’t want to become stranded if your battery dies. One of the worst possible outcomes of using a poor-quality trolling motor battery is that you could become stranded. This shouldn’t be a problem for anglers who also use an outboard motor, but for kayakers who rely solely on their trolling motor for propulsion, this could cause you to become stranded miles from the boat ramp.
  • You want a battery that will last for years of use. From a value standpoint, you don’t want to buy a battery that will require replacement in six months. Instead, you want to purchase a high-quality battery, which will function well for years. This will not only ensure that you get better value for your dollar, but it will also help you avoid having to repeatedly shop for replacements.

 

How to Choose Your Next Trolling Motor Battery

trolling motor battery test

Whether you choose one of the batteries listed above, or you select some other model, you’ll want to consider a few key criteria when purchasing your next trolling motor battery.

Battery Types

There are a variety of different battery types available, but two types are typically used to power trolling motors: lead-acid wet cell batteries and absorbed glass mat (AGM) batteries.

The former are typically more affordable, but they require the user to add water periodically, while those in the latter category require no maintenance and typically last longer. However, AGM batteries are typically more expensive than their lead-acid counterparts.

Weight

Trolling motor battery weight isn’t always a factor for anglers. Some individuals won’t mind lugging around a 70-pound battery and wrestling with it during installation or removal. However, most anglers will appreciate the convenience lightweight batteries provide.

No matter which camp you fall into, just be sure to note the weight of any battery before you make your purchase.

Amp Hour Rating

A battery’s amp-hour rating essentially indicates the length of time a battery will work for at a given amperage. For example, if you select a 100 amp-hour battery, it should provide 4 amps for about 25 hours.

This is one of the most important characteristics to consider for many anglers – particularly those who like to go on long trips or use trolling motors that draw a lot of amps.

Cold Cranking Amps

Cold cranking amps are an important consideration for many applications, but this rating is not terribly important for those seeking a trolling motor battery. Instead, you’ll want to primarily focus on the battery’s reserve capacity.

Charging Time

If you enjoy fishing frequently, and you like to take multiple trips in the same day, it is imperative that you select a battery that features a brief charging time. Otherwise, you may find it necessary to remove the battery before it is completely finished charging.

On the other hand, if you only fish on the weekends, charging time isn’t a terribly important selection criterion, as you’ll have several days to recharge your battery between uses.

 

Top Brands

Although there are a number of battery manufacturers and brands, the majority of those used by anglers and boaters are produced by a relative handful of companies. This is actually beneficial to buyers, as it makes it easier to narrow down the number of brands you’ll need to consider when making your choice.

We’ll discuss three of the most noteworthy trolling motor battery manufacturers below.

Interstate Batteries

Interstate Batteries

Interstate Batteries is one of the leading manufacturers in the battery category. They make batteries for just about every application available, ranging from golf carts to farm tractors to trolling motors.

The company produces both budget-priced and high-end options, so they can represent a great source for buyers at all ends of the price spectrum.

One of the nice things about this manufacturer is that they maintain retail locations in many metropolitan areas. This can make it easier to deal with warranty issues or battery problems, as you won’t need to ship the battery for repair (which can be expensive).

 

Mighty Max

Mighty Max

Mighty Max produces a range of products, including not only trolling motor batteries but chargers and solar panels too. However, batteries do represent the bulk of their product line. They produce batteries designed for a variety of applications, ranging from two-way radios to vacuums to remote-control toys.

Most of their trolling motor batteries are rather affordable, and several provide excellent value for their price. Mighty Max offers a number of multi-battery packages, which enable buyers to enjoy additional savings. Given these factors, Mighty Max is a great manufacturer for budget-limited buyers to consider.

 

Vmax

Vmax prides themselves on producing “tough batteries for tough applications,” which makes them an ideal manufacturer for trolling motor batteries. Unlike some other companies, which try to produce low-cost batteries for cash-strapped buyers, Vmax primarily focuses on producing high-quality batteries, which are built to last.

Vmax produces batteries designed for a variety of applications. They offer batteries for forklifts, cars and jet skis, as well as trolling motors. Many of their batteries boast high-end, innovative features, and they are typically some of the best batteries available for any given application.

 

Trolling Motor Battery FAQs

A lot of anglers and boaters have questions about trolling motor batteries. We obviously can’t answer all of the questions potential buyers may have, but we’ll try to address a few of the most common ones below.

What size battery do I need?

Different trolling motors require different batteries for optimal operation, so consult the information your trolling motor manufacturer provided before you start shopping. Additionally, it is important to consider the space you have available, as trolling motor batteries vary significantly in terms of size.

Of course, you’ll also need to consider the amount of power you need the battery to deliver, as well as the amp-hour rating it bears, which will help you determine how long you can operate it between charges.

Can a trolling motor battery get wet?

trolling motor battery in boat

Trolling motor batteries designed specifically for such use can become wet from splashing water or rain without issue. However, this does not mean they can be safely submerged – particularly if the battery is not sealed.

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

Some trolling motor batteries may feature terminals that won’t match up properly with your motor. You’ll simply need to inspect the motor’s terminals and select a battery with compatible terminals. However, it is usually not very difficult to purchase conversion kits, which make it possible to account for differences in terminal style.

Should you let a lead-acid battery discharge completely between charges?

Waterproof and shockproof charger

No. This is based on a myth that batteries have a “memory.” This is not true at all, and it may cause your battery to fail prematurely. Instead, charge your battery regularly and slowly for best performance. Most people who believe this myth probably do so because of a bad experience with a poor-quality battery.

***

There are a number of very high-quality trolling motor batteries on the market, but we encourage our readers to start their selection process by considering the eight models described above. Each of the ones we recommend should work well and give you the chance to enjoy hours of problem-free trolling fun.

Just be sure that you select one that is designed for your specific trolling motor and will fit in the space you have available.
