Best Trolling Motor Battery | Buyer’s Guide & Reviews | 2021
Picking a reliable battery for a trolling motor is a key consideration for any boat owner. Trolling motors are not just to propel smaller boats, they are also regularly used with canoes and kayaks. If you have upgraded your watercraft to include a trolling motor, you should not skimp on the battery. A trolling motor battery provides a steady discharge of electricity that provides your motor with the power it needs to operate. The best batteries will also provide you with a power feed for smaller electronics you might have with you. There are many different things you should be bearing in mind when selecting the best trolling motor battery for your needs. Our guide breaks down all the things you should considering when selecting a suitable battery for your trolling motor.
Trolling Motor Battery Types
Before purchasing a new marine battery, make sure that it is compatible with your trolling motor. Some trolling motors will require a specific kind of battery in order to function, however others will have more universal compatibility. Any battery you buy should offer you a large reserve capacity to keep you going for longer. You should also make sure your battery is safe to use on the water, with a heavy-duty design that will cope with exposure to water and handle excessive vibrations and impacts with ease.
One of the most common options to consider when selecting a marine battery is a wet lead acid battery. These types of battery are often also referred to as flooded lead acid batteries. The reason these types of batteries are referred to as ‘wet’ is because they include electrolyte fluid. This fluid submerges the internal plates. While these batteries are powerful and reliable, they do require some basic degree of maintenance. You will need to carry out regular checks on electrolyte levels and may also need to replenish water levels over time. Although they have some drawbacks, wet-cell batteries are more long-lasting than other types. They are also relatively inexpensive when compared to other battery varieties. While the low cost and longevity of wet-cell batteries makes them an enticing option, you should be confident enough that you can carry out the ongoing maintenance of them to ensure they operate effectively.
Batteries filled with a gel substance are another option to consider. The inclusion of this viscous fluid makes them very resilient to vibrations from running trolling motors. Although the gel fluid serves to power the battery itself, it also provides it with essential protection that makes them a good candidate for marine activities. A downside to gel-filled batteries is that they are hard to inspect and carry out maintenance on. You are also limited when it comes to the hardware you can use with them. If you invest in a rechargeable gel battery, you will also probably need to purchase a specialised gel battery charger as well. The main reason for this is because such batteries require a far lower voltage than conventional batteries. If you can afford the added expense of the charger, gel batteries are worth considering. However, the batteries themselves can cost more than standard alternatives.
Sealed Lead Acid Batteries
Sealed lead acid batteries, otherwise known as AGM batteries, are a popular option with many boat owners. These batteries use electrolyte absorbed mats in order to provide power to your motors. This design allows for oxygen and hydrogen to carry out a chemical reaction in order to produce water naturally. This makes these batteries very versatile, allowing them to be mounted in a variety of places. With these batteries, you do not need to worry that much about vibration damaging the integrity of the build. They also provide continuous charge over lengthy periods of time. As such, they are the preferred option of many looking to power trolling motors. In terms of lifespan, these batteries also impress, making them a cost-effective option. However, the consequence of this is that sealed lead acid batteries are fairly expensive. However, a significant initial investment will result in cost-savings down the line.
