The Best Trolling Motor Batteries
The VMAX V35-857 12 Volt 35AH AGM Deep Cycle Group U1 Battery offers a lower price than the Weize battery. It’s a heavy-duty for an edge in performance and service life, whether using on standby or repetitive usage. It measures 7.7 x 5 x 6.1 inches making it a little smaller and better for less space or smaller boats.
Exceptional treatment during the manufacturing process ensures the battery is both reliable and powerful, making it a superior option. The battery also resists issues related to vibrations thanks to the AGM technology. Next, hermetically filled plates and electrolytes are sealed to prevent spillovers.
If you plan to store your battery and not use it consistently, though, you may want to consider a different option because this one will lose charge exponentially. It is, however, a maintenance-free operation battery with no need to check the specific gravity of the electrolytes or add water during the float service life.
Finally, the battery has a fast recharge rate and offers 12 volts of power and weighs 25 pounds making it significantly lighter than the option above. Get 4 to 9 hours of run time, depending on usage.

Understanding the Best Trolling Motor Battery
Batteries come with a list of jargon most people don’t understand, and we would like to help you understand some of the words associated with batteries. With knowledge, you can make the best decision and get out on your boat equipped to make better decisions. Take a look.
AGM sounds like a high tech word because it is a high tech word! It stands for Absorbed Glass Mat and basically refers to a specific type of lead-acid battery. Moreover, its an advanced lead-acid battery that can provide superior power to support higher demands in vehicles with start and stop applications like your boat. With AGM, you can get a reduced weight battery with improved reliability. These batteries are also spill-proof, making them safer.
A deep cycle refers to a lead battery designed to provide power over a long period of time. The sustained power can run more reliably until it is about 80 percent discharged or more, then it will need to be recharged. Other styles of batteries only provide short bursts of energy before they need recharging, but vehicles tend to need more energy like your favorite boat. The most common styles are flooded deep cycle batteries which are sealed and do not require maintenance.
Float Use vs. Cyclic Use
Float use refers to the standby use of a battery as in, using it as an alternative source of power instead of the main source of power. Meanwhile, a cyclic use is also the same as a deep cycle battery, which means it can be discharged and recharged over and over again. The latter has a battery lifespan of up to 1000 charges and discharges before you need to replace the battery.
A lithium-ion battery does not use lead or acid to make the battery but instead lithium ions to power devices. It’s the stuff used to power a smartphone. These batteries are extremely lightweight and take up dramatically less space than other styles of batteries, but you pay more for these batteries. They also charge faster, and the low weight can even increase speed.
Maintenance & Safety
The batteries on this list do not require maintenance, which is why they made the cut! Moreover, they all come with a thick plastic casing to insulate and protect the batteries from vibrations and exterior issues. Always make sure to practice safety precautions when installing or removing a battery from your motor. Read the instructions carefully before use and follow all recommended procedures.

Questions About Best Trolling Motor Battery
How long will a battery last per charge?
How long your battery lasts per charge depends on your usage and type of battery. If you are traveling at high speed and pulling a heavy load, the battery will run out in a couple of hours. Less use means the battery will last longer. To calculate your usage, divide the amp hours in the battery by the amp available in the motor. For example, 100 amp-hours with a 20 amp motor at midrange speed affords you about five hours of battery run time.
How long does it take to charge a trolling motor battery?
Lithium-ion batteries charge faster than the other options like AGM batteries or deep cycle. The length of time depends fully on the amps available in your charger. The higher the amps in the charger and the faster it will be able to charge your battery. On average, it takes about 12 hours to recharge an AGM battery.
What’s the best way to store my battery?
First, make sure you charge your battery as soon as possible after you get back from boating. A charged battery will store longer than a dead battery and will be easier to re-cycle. Like with any other battery, the longer length of time between charges, the harder it will be to regain a charge. Otherwise, make sure to store the battery in a cool and dry area, and if your battery requires water, make sure to add as needed based on the instructions.
