Practically everybody is familiar with SLI-type batteries. These are the kind you see in automotive applications. They power starting motors or car radios while the car is off. You don’t want to use an SLI battery to power your trolling motor. The best trolling motor battery is a deep cycle design. While SLI-type batteries are designed for short high-energy bursts, deep cycle batteries are set up to provide optimum performance over extended periods of time with a constant discharge rate.

We evaluated the top deep cycle batteries for marine applications to discover the two best designs. In general you get what you spend for. The most costly batteries provide more tested reliability and more effective power for trolling motor operations. Still, there are a couple of cheaper and affordable options that will work.

Regardless of what your budget plan is, do not be the angler who hooks two or three car batteries to your trolling motor. SLI batteries aren’t produced the job. They develop irregular power outputs that could disrupt motor operation, cause excess noise, and cause fish to swim away.

The Optima BlueTopBest Trolling Motor Battery

Optima is among the undisputed leaders in battery design and building. Their BlueTop deep cycle batteries were developed particularly for hard marine applications. Although a bit more costly than some other alternatives, Optima guarantees up to three times as numerous recharges as leading competitor batteries. This implies that you can acquire numerous impersonator brands, wait for them to break, and the BlueTop will still be charging up.

Furthermore, Optima batteries are developed with vibration resistance. Continuous wave or motor vibrations can cause the plates in batteries to move and become damaged. Optima uses injury building called SPIRALCELL technology. It minimizes the damage triggered by vibrations. This is a true benefit over a plate style that can totally fall apart and break down under the stress of boating applications.

The Optima is also spill evidence. The BlueTop is entirely sealed so that battery acid can’t leak out. First, this allows mounting in any position, throughout the boat. Second, it makes the BlueTop environmentally much safer than many other battery styles.

One major issue with deep cycle batteries is self-discharge. Over time, rechargeable batteries can lose a few of their power while in storage. One of the best functions of the BlueTop is its ability to sit for the entire off season (several months) and still hold a charge. As long as the battery is kept at or listed below space temperature level, it will remain prepared to go and charged for one year.

You can’t go wrong with Optima. They are a market leader in marine applications for an excellent reason. The BlueTop is pricy, but in our viewpoint it’s the best deep cycle battery for a trolling motor. In addition, the BlueTop likewise works as a starting battery.

The Interstate DCM0035The Interstate DCM0035

At about half the price, the Interstate DCM0035 is a solid option to the Optima BlueTop. The Interstate Design delivers similar performance and dependably with minimal downsides.

Interstate is the number one brand in America for replacement batteries. They’ve been creating and building batteries for over half of a century and they understand how to do it well. Innovation and innovation are the huge distinctions between Interstate and Optima. Interstate does incorporate brand-new innovation into their items, they just do not prefer to show it off. They develop reliable, plain, unassuming products that do not stand out with the exact same elegant confidence as Optima batteries.

For most applications, the Interstate DCM0035 is going to work completely. The robust plate provides extended life, and a computer-generated grid design supplies optimum high-power density. Interstate doesn’t use the spiral wrapped technology of the Optima, so it may be vulnerable to harm due to vibrations. Most people we know, however, do not have any issues with it.

The DCM0035 is sealed in a thermally welded case with a bond that prevents leakage. Similar to the optima, it can be used in any orientation.

In general, the Interstate DCM0035 is an excellent battery. It isn’t really the best offered, however it can be found in at a close second. Optima takes the top spot with sophisticated technology and an advanced design that avoids vibration damage.
