Batteries are pretty heavy, ranging from Fish Finder Battery pounds, and on a fishing vessel, chances are you’ll have at least two. On top of that, the size is smaller and more portable, allowing for use in almost any boat. The weight is 43.5 pounds, and the dimensions are 10×6.75×7.8 inches. Flooded wet-cell batteries are less expensive, but they don’t perform as well as the other choices. Wet cell batteries can spill acid, so they don’t stand up to vibration well and have to be mounted in a level position.

If you use your trolling motor at lower speeds, you will have a significantly lower current draw and much longer run time. They have a maximum discharge current of 100A, which is well above what trolling motors need. Throughout this article, we’ve covered four different types of batteries. Car batteries, Sealed lead acid deep-cycle, absorbed glass mat deep-cycle, and lithium-ion deep-cycle. We’ve digested the pros and cons of each and why they would be a good fit or not such a great one.

Lithium batteries are one of the latest trends for high power and low weight. The Tracker Lithium Super High Output Battery is ready for action. Compared to a lead-acid battery with an average of 270 recharges, the Tracker Lithium can be powered over 5,000 times. It’s also capable of deep cycle usage, adding a little versatility to this package. At $249 for the Group 27 model, this is one of the more affordable batteries for trolling motor use—great for anyone just starting out or anyone who doesn’t want to spend a ton of money.

Assessing Your Marine Battery For Trolling Motor Options

While this calculator offers numerous advantages, it also has limitations that users should be aware of to ensure balanced decision-making. The Minn Kota Ulterra motor is my personal favorite extremely lightweight brand to use with Humminbird electronics. The Ulterra has a range of advanced features, including Auto Stow/Deploy, which allows you to easily raise and lower the motor with the push of a button. [newline]This isn’t a major added time-suck, but wet batteries do require slightly more care than other types.

The most common ones are lead-acid batteries, AGM batteries, and Lithium-ion batteries. Lithium batteries, on the other hand, can be regularly discharged to 80% and still last hold the charge after 5 and more years. Remember to factor in any additional electrical equipment that may be using power from the battery while trolling.

This model is on the smaller size of batteries we’ve discussed today. The Weize weighs 23.1 pounds with dimensions of 7.68 x 5.12 x 6.10 inches, making it small and portable. This battery also has 35 Amp Hours (run time), the lowest energy output on our list. But it will still get the job done for a small kayak trolling motor.

The electrolyte suspension system absorbs electrolytes without contaminants for pure power transfer. Heavy-duty, tin-alloy cells improve performance in floating or cyclical charging. Before putting on charge, always check the level of the electrolytes and that they are below the level of the splash barrel of the split ring. If the water levels in the battery are low, top them up using either distilled or deionized water only.

Centennial’s main difference from Interstate is that its batteries are closed – no liquids or tapers have to be checked. 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. Purchasing the best brand for motor batteries can be tricky, but fellow anglers are hyping some brands.

This probably isn’t important if you charge your trolling motor battery overnight. However, fast charging brings about the possibility of recharging your batteries during the day or using a powerful outboard alternator or generator to top up your lithium battery. On the other hand, dual-purpose marine batteries give you the best of both worlds. With this battery type, you’re receiving cold-cranking amps and deep cycle power. SLA wet cell batteries have been around longer, which makes it a cheaper option. However, AGM batteries have better qualities, making the extra couple of bucks worth it.
