Best Trolling Motor Battery Overall: Weize Deep Cycle Battery

Highly-regarded for its substantial power, unquestionable reliability, and convenient design, the Weize Deep Cycle Battery is the best battery you can buy for your trolling motor. It’s a deep cycle battery, which means that it has been designed to run at a low voltage for a long period of time, and it can withstand consistent discharge from week-to-week, day-to-day, or however often you use your motor. The 100 ampere-hour capacity provides a large reservoir of power to draw from that can power a trolling motor for an entire day on the lake.

This Weize Deep Cycle Battery is a valve-regulated sealed lead acid battery that requires no maintenance and is virtually spillproof. It has a heavy-duty calcium-alloy grid that is mated with absorbed glass mat technology, meaning that there is fiberglass sandwiched between the lead plates that are highly resistant to vibration and are soaked in battery acid. All of this technology results in a battery with a long lifespan that can easily recover from deep discharges.

Though this battery can be used for many applications from golf carts to RVs and sump pumps, it excels as a marine trolling motor battery. The outer shell has been designed to reduce heat build-up, and it has been fitted with a convenient rope carry handle. The terminals support gaiter clips and bolt-on connections. This excellent trolling motor battery comes backed by a 12-month warranty.

Who Should Buy A Trolling Motor Battery

Every person who owns a small boat with a trolling motor should have at least one trolling motor battery, if not several. Trolling motors are the best way to move a vessel at low speeds on any water surface. They are best used for fishing, bird watching, and relaxed open water travel. Canoes, kayaks, and rafts can all be equipped with trolling motors as well. Every electric trolling motor should be paired with an adequate sized battery to keep it running for hours without fail.

The best way to mount a trolling motor battery is with a marine battery box. With the right setup, you’ll have the power you need at all times, and the battery will be securely mounted in place where it can be easily accessed and will be safely protected from the elements.

Important Features to Consider

There are a few important considerations to think through before purchasing a trolling motor battery.

  • Battery type. It’s important to know the difference between the three types of trolling motor batteries. There are starter or cranking batteries that are designed to start a trolling motor, there are deep cycle batteries that are designed to run a motor for a long period of time once it has already been started, and there are dual-purpose batteries which do their best to tackle both jobs within a single battery. Using separate cranking and deep cycle batteries is the more efficient option, but a dual-purpose battery is more convenient.
  • Amp capacity. The amp capacity, otherwise known as ampere-hours, is how much energy the battery can store. The larger the amp capacity, the more energy it will hold, and the longer it will run.
  • AGM or GEL. Absorbed glass mat batteries can tolerate a deeper discharge depth, are highly resistant to shock and vibration, and they can tolerate extreme temperatures well. GEL batteries are also sealed and spill-proof batteries just like AGM batteries, but some do have the option of being refilled with additional electrolytes which can lengthen the lifespan of the battery. Both types work well for trolling motors.
  • Weight and size. Along with more power and capability also comes increased size and weight. You’ll want to consider how big and heavy your batteries will be as this too will have an effect on your boating experience. Be sure that the battery you purchase can be mounted in the position that you need, as not all batteries can be mounted sideways.

Frequently Asked Questions

How long will a trolling motor run on a battery?

The larger a trolling motor battery’s amp capacity, the more power it can hold, and the longer length of time it will be able to operate. How long a specific battery will last also depends on how powerful your trolling motor is and how fast you want to travel across the water. Trolling motors will typically list their maximum amp draw. You can estimate how long your battery will last by dividing its amp capacity, or ampere-hours, by the trolling motor’s amp draw. If your battery has a 100 amp capacity, and your motor draws 10 amps per hour, the battery will run for about 10 hours.

Will my car battery work for my trolling motor?

No, it will not. Your vehicle’s battery is not a marine battery, and it has been designed for a totally different set of circumstances. A car battery needs to crank up a car’s starter motor, and it is being consistently charged while the vehicle is in operation. Deep cycle trolling batteries are designed to operate at low draw levels, and they can be fully consistently discharged and used again. Using a car battery for a trolling motor can ruin both the battery and the motor.

How often should I charge my trolling motor battery?

You should charge your deep cycle battery as soon as you are done using it for the day. If the battery is left at low or no charge, this will ruin the battery’s capacity to fully charge and drastically shorten its lifespan. You should only use deep cycle battery charges to charge a deep cycle battery.

What is a cranking starter battery?

A cranking starter battery is a separate battery from your deep cycle trolling motor battery. Cranking starter batteries are used to start a motor, while deep cycle batteries are used to run a motor once it has been started. Dual-purpose batteries combine both of these capabilities into one battery, but they are typically less efficient than running two separate batteries, each for its intended task. A cranking battery should never be used to run your motor long term as repeated discharges can ruin a cranking starter battery. Deep cycle batteries are generally unable to start a trolling motor.
