10 Best Minn Kota Trolling Motor Batteries 2025 in the United States

The Dakota Lithium 12V 135Ah battery is a lithium iron phosphate (LiFePO4) deep cycle battery designed for trolling motors and other powersports uses. Compared to traditional lead-acid batteries, it offers significant advantages like longer lifespan—over 2,000 charge cycles versus about 500 for lead-acid—which means it can last several years with regular use. It’s also much lighter at around 29 pounds, making it easier to handle and transport. The battery includes built-in smart electronics (Battery Management System) to protect against overcharging, overheating, and short circuits, improving safety and reliability.

Its voltage and capacity are well suited to power trolling motors efficiently, while also being versatile enough for RVs, golf carts, and solar setups. The battery carries an impressive 11-year warranty and is designed to perform well even in cold temperatures. This battery could be a good fit if you want a durable, lightweight, low-maintenance power source that charges quickly and lasts much longer than traditional batteries, especially suitable for frequent or long-term use in boating and outdoor activities.

The OPTIMA D34M BlueTop battery is a solid choice for Minn Kota trolling motor users who need a reliable power source that can handle both starting your boat’s engine and running a trolling motor. It’s a sealed AGM (Absorbed Glass Mat) battery, which means it doesn’t require maintenance like adding water, making it convenient and mess-free. At 12 volts and 55 amp-hours, it provides a decent amount of power for typical fishing trips, while its 750 cold cranking amps ensure strong starting power even in cold weather.

One of its standout features is its SpiralCell technology, which uses pure lead to offer more consistent power and longer life than regular batteries. This battery is also built to resist vibration much better than standard flooded batteries, making it durable and well-suited to the bumps and movement common on boats. With a reserve capacity of 120 minutes, it can deliver steady power for extended periods, which is important when trolling or running electronics.

Weighing 43.5 pounds, the battery is somewhat heavy, so weight should be considered depending on your setup. The dual terminal design offers flexibility in connections, useful for various boat wiring configurations. This battery is maintenance-free, reliable, and provides a good balance between starting power and deep cycle capability, making it a versatile option for anglers and boaters seeking dependable performance without extra upkeep.

The VMAX MR137-120 batteries come as a pair of 12V, 120Ah AGM deep cycle batteries, designed especially for saltwater trolling motors like the Minn Kota Riptide RT80. Their deep cycle AGM design means they provide reliable and long-lasting power, which is ideal for users who need steady energy for extended fishing trips. At 120 amp hours each, these batteries offer a strong capacity for a 24V trolling motor setup when used together, helping you run your motor efficiently without frequent recharging.

Being maintenance-free is a major plus—there’s no need to add water or check the electrolyte, and they can be mounted in any position, which adds convenience. Their sealed design also helps resist shocks and vibrations, important for rough water conditions. However, each battery weighs 75 pounds, so they’re quite heavy and may be difficult to carry or install without help. The 1-year warranty covers replacement, but some users might prefer longer coverage for peace of mind.

These batteries are solid choices for serious anglers looking for durable and maintenance-free power, though the weight and relatively short warranty might be drawbacks for occasional users or those seeking lighter, portable options.
