What is a Deep Cycle Battery?

A deep cycle battery is a unique kind intended to withstand multiple rounds of discharging and recharging without damaging its internal parts. Unlike starter batteries that deliver a sudden surge of power to start engines, deep cycle batteries provide a consistent and continuous power flow over an extended duration. These batteries are widely used in various applications, such as trolling motors, recreational vehicles (RVs), and solar power systems.

Types of Deep Cycle Batteries:

There are three main types of deep cycle batteries to consider when choosing the best battery for your trolling motor:

Flooded Lead-Acid Batteries:

The most common type of deep cycle battery is a “flooded lead-acid battery.” They are easy to find, affordable, and work well. But you need to take care of them by adding water to the battery and regularly cleaning the metal parts ( terminals ).

Absorbent Glass Mat (AGM) Batteries:

AGM batteries are a special kind of battery you don’t need to take care of too much. They cost more than flooded lead-acid batteries but last longer and are stronger. You don’t have to worry about them leaking; you can put them in any position you want.

Lithium-Ion Batteries:

Lithium-ion batteries are a new kind of deep cycle battery. They cost more than other batteries. They are light and last a long time. They only need a little upkeep. They charge quickly and hold more energy than other batteries. But they are the most expensive choice.

Why Do You Need a Deep Cycle Battery for Your Trolling Motor?

A trolling motor needs a particular battery to power it for several hours. This kind of battery is called a deep cycle battery. It’s not like the battery in a regular car that only gives a quick burst of power to start the engine. The deep cycle battery provides a steady amount of power for a longer period, making it perfect for trolling motor use.

Understanding Amp-Hours:

When buying a battery for your trolling motor that will last a long time, you should consider its “Amp-hours” (Ah). This is how much energy the battery can provide over time. If a battery has more Ah, it will work for a longer time before you need to recharge it.

For example, a battery with a rating of 100Ah will last twice as long as a battery with a rating of 50Ah, if you use them both similarly.

Factors to Consider When Choosing a Deep Cycle Battery for Trolling Motor:

There are several factors to consider when choosing a deep cycle battery for your trolling motor. These include:

Battery Capacity:

Battery capacity is measured in amp-hours (Ah). A higher amp-hour rating means the battery will last longer. So, when choosing a battery for your trolling motor, pick one with a good amp-hour rating that can power your motor throughout your trip. Remember, this is important because you want to stay in power while on your journey.

Battery Type:

There are various types of batteries called deep cycle batteries. These include flooded lead-acid batteries, sealed lead-acid batteries, and lithium-ion batteries. Each kind of battery has its benefits and drawbacks. Flooded lead-acid batteries are the most common and usually the cheapest option but not well option compared to the other batteries. Sealed lead-acid batteries don’t require any maintenance and don’t need water to be added. Lithium-ion batteries provide the most energy per unit and last the longest, but they are the most expensive choice but recommended.

Battery Voltage:

The power of a battery depends on its voltage. Trolling motors need a 12, 24, or 36 volts battery. You should pick a battery with the right voltage for your motor.

Battery Size and Weight:

When selecting a battery for your boat, consider its size and weight. If you have limited space, a smaller battery may be more suitable since it’s lighter and easier to handle. However, a smaller battery may not provide enough power if you have a bigger trolling motor. Therefore, it’s crucial to find a battery that fits your requirements in terms of size and weight.

How to Maintain Your Deep Cycle Battery for Trolling Motor:

Proper maintenance is key to ensuring the longevity and performance of your deep cycle battery. Here are some tips for maintaining your battery:

  1. Make sure to fully charge your battery after use to prepare for your next trip.
  2. Keep your battery in a cool and dry place when you’re not using it. Heat and moisture can harm it.
  3. If you have a flooded lead-acid battery, check its water levels often and add distilled water as needed.
  4. Clean the battery connections regularly to prevent corrosion. You can use baking soda and water to clean them and a wire brush to scrub off any corrosion.
  5. Use a charger/maintainer designed for deep cycle batteries to keep your battery charged and ready to use.
  6. Check your battery regularly for any signs of damage or wear. If you notice any problems, fix them immediately to prevent further damage.
