Why Choosing the Right Trolling Motor Battery Is Critical
Choosing the right battery isn’t just some minor detail—it’s the ace up your sleeve for any fishing trip. A good battery doesn’t quit halfway through the day, leaving you stranded. It’s about endurance, ensuring the motor runs without any hiccups. You want to avoid things like the motor overheating or taking a sudden nosedive in power, both of which can ruin your day. Opting for a maintenance-free choice like an AGM battery is smart; they resist shaking and last longer. AGM batteries usually outlive the old-school lead-acid ones, sticking around for about 2 to 3 years if you give them some love (Kokanee Addict Fishing). Whether you’re considering lead-acid, AGM, or lithium-ion, knowing what’s out there can help you land the perfect catch of a battery.
How We Selected the Best 7+ Trolling Motor Batteries

They stand tall over their lead-acid and AGM cousins, winning the endurance game and offering deep cycles that others just can’t match.
While doing my legwork, I zeroed in on what makes each battery tick—especially how long they’ll keep your motor singing and the ease of use. For some folks, an AGM battery is just the ticket; they’re less fuss than the wet cell types (Outdoor Life). After all this number-crunching and fact-finding, I whittled it down to a list of the top 7+ trolling motor batteries, perfect for those who want more smooth sailing and less sputtering in their fishing adventures.

Buyer’s Guide
Key Features: Battery Type, Capacity, and Lifespan
Choosing the right trolling motor batteries can make or break a day out on the water. Let’s break down the main things to look out for: battery type, capacity, and lifespan.
Battery Type
Got a few choices here, and each one has its quirks and perks:
| Battery Type | What’s the Deal? | Price Ballpark |
|---|---|---|
| Flooded Lead-Acid | Cheap and cheerful for those who don’t go out often. These usually won’t break a hundred bucks. Great for folks counting pennies. (Manly Battery) | $50 – $100 |
| AGM (Absorbed Glass Mat) | Hassle-free and versatile, solid for regular boaters who want good bang for their buck. (Manly Battery) | $100 – $300 |
| Lithium (LiFePO4) | They’ll cost you more upfront, but they’re lighter, last longer, and work like a charm. Worth it for those who are always on the water. (Kokanee Addict Fishing) | $300 – $1,200 |
Capacity
This one’s all about stamina. Capacity, measured in amp-hours (Ah), shows how long the battery can keep going. Bigger trips? Go for a battery that can hold more power. Factor in how much juice your motor pulls and how long you’ll float.
| Battery Capacity (Ah) | How Long It’ll Last (hrs) | Motor Muscle (lbs) |
|---|---|---|
| 50 | 3 – 5 | Up to 30 |
| 100 | 5 – 10 | Up to 55 |
| 200 | 10 – 20 | Up to 75 |
Lifespan
How long before the battery bites the dust? Lithium takes the trophy here, outlasting others by a long shot. They keep a steady voltage going and don’t dip as they drain. (UFine Battery)
| Battery Type | Time Until Retirement |
|---|---|
| Flooded Lead-Acid | 2 – 5 years |
| AGM | 4 – 6 years |
| Lithium (LiFePO4) | Up to 10 years |
