How to Choose the Best Battery for Trolling Motor

Heading out on the water for a relaxing day of fishing is one of life’s great joys. But nothing can ruin your angling adventures faster than a dead trolling motor battery. The right power source is essential for maneuvering your boat into prime fishing spots quietly and efficiently.

When choosing a trolling motor battery, you need one that provides plenty of juice for extended trips. But with so many battery options on the market, how do you pick the perfect one? Don’t worry, we’ve got you covered. I’ll walk you through everything you need to know to find the ideal battery for your trolling motor needs.

1. Determine Your Power Requirements

The first step is figuring out the power requirements for your specific motor. Talk to the manufacturer to find the recommended battery capacity and voltage. Generally, a 12V deep cycle marine battery is best for most trolling motors.

For the motor thrust, you’ll typically need around 50-100 amp hours for every 100 lbs of thrust. So if you have a 50lb thrust motor, choose a 50-100 AH battery. Go with 100-200 AH for a 100lb thrust. When in doubt, get a battery with more capacity than you think you’ll need for maximum running time.

2. Consider the Battery Type

Two popular options are flooded lead-acid and absorbed glass mat (AGM) batteries. Here’s how they compare:

  • Flooded Lead-Acid – These affordable batteries have freely flowing electrolyte fluid. They’re easy to maintain by adding distilled water as needed. Just be sure to install them upright and properly vented.
  • AGM – Absorbed electrolyte and sealed construction makes AGMs spillproof and mountable in any position. They charge faster, produce less hydrogen gas, and have a longer lifespan than flooded batteries. But they cost more upfront.

3. Check the Physical Size

Make sure the battery dimensions fit the allotted space on your boat. AGM and other sealed batteries are often preferable for small, cramped areas since they don’t require much ventilation room.

4. Buy From Reputable Brands

Stick with trusted manufacturers like Optima, Odyssey, or VMAX. Their batteries undergo rigorous testing and quality control checks. This gives you assurance the battery will perform well season after season.

5. Find the Best Price

Battery prices range widely from $100 on the low end to $400+ for premium models. Set a reasonable budget and look for sales to get the most bang for your buck. Just make sure to prioritize quality and longevity over bargain hunting.

Frequently Asked Questions When Picking the Best Battery for Trolling Motor

1. What type of battery is best for a trolling motor?

The two most common options are flooded lead-acid batteries and absorbed glass mat (AGM) batteries. AGM batteries are spill-proof, mountable in any position, and have a longer lifespan. But flooded batteries tend to be more affordable. For trolling motors, a 12V deep cycle marine battery is recommended.

2. How much battery capacity do I need?

Aim for 50-100 amp hours per 100 lbs of thrust. For example, choose a 50-100 AH battery for a 50lb thrust motor, or a 100-200 AH battery for a 100lb thrust motor. More capacity equals longer running times.

3. What brands make the best trolling motor batteries?

Top manufacturers known for reliable, durable batteries include Optima, Odyssey, VMAX, Trojan, and Lifeline. Buying from established brands means getting a high-quality battery designed for marine use.

4. How much do trolling motor batteries cost?

Expect to pay $100 on the low end for budget flooded lead-acid batteries up to $400+ for high-end AGM models. Set a reasonable budget and look for sales, but don’t sacrifice too much quality for the price.

5. How long should a trolling motor battery last?

With proper care and maintenance, a good deep cycle battery can last 3-5 years or more. Lithium ion batteries have a longer 5-10 year lifespan. Usage and recharging impact longevity.

6. Can you mount the battery in any position?

AGM and lithium batteries can mount in any position. Flooded lead-acid batteries need to stay upright to avoid leaking or spillage. Make sure there is adequate ventilation if installing a flooded battery in an enclosed space.

7. How do I recharge my trolling motor battery?

Use a battery charger designed for marine deep cycle batteries. Don’t use a car battery charger. For best performance, avoid running the battery below 50% capacity before recharging. Never leave a discharged battery unattended for long.

8. What size battery will fit my boat?

Check battery dimensions and required ventilation space. Sealed AGM or lithium batteries are better for small, cramped spaces on boats. Always securely mount the battery to avoid damage from shifting during use.

Final Thoughts

Finding the right battery is a key factor in powering your trolling motor for a successful fishing trip. By determining your thrust requirements, considering battery types, checking physical size limitations, choosing quality brands, comparing prices and reviews, and asking the right questions, you can identify the ideal battery for your needs. Investing in a reliable, high-performance trolling motor battery means enjoying hours of quiet cruising to the best fishing spots on the water. With the tips provided in this post, you can have peace of mind knowing your battery will deliver power all day long so you can focus on landing the big catch. The next step is getting your gear prepped for a day filled with family fun on the water!
