For avid anglers who rely on cutting-edge sonar technology like Garmin’s Livescope, ensuring that their equipment is powered efficiently is a top priority. One common question many fishermen ask is, “Can I use a deep cycle battery for Livescope?” In this article, we’ll dive into whether deep cycle batteries are suitable for Livescope, the benefits of using one, and how to choose the best battery for your fishing needs.
Livescope technology requires a reliable power source to function optimally during long hours on the water. As deep cycle batteries are designed to provide consistent power over extended periods, they have become a popular choice among anglers. But is a deep cycle battery the best option for your Livescope setup?
Can I Use a Deep Cycle Battery for Livescope?
Yes, you can use a deep cycle battery for Livescope, and it is actually a preferred option for many anglers. Livescope units require a significant amount of power, especially if you’re out on the water for long fishing trips. Deep cycle batteries are built to provide steady power over time, making them ideal for applications like running sonar and fish-finding equipment.
A deep cycle battery offers several advantages:
- Long-lasting Power: Unlike cranking batteries that are designed to give short bursts of power, deep cycle batteries can sustain continuous use, which is essential for electronics like Livescope.
- Durability: Deep cycle batteries are designed to be discharged and recharged multiple times, which extends their life and makes them perfect for repetitive use.
- Steady Power Output: Since Livescope requires consistent power for optimal performance, a deep cycle battery’s ability to deliver stable voltage is an important benefit.

Why Use a Deep Cycle Battery for Livescope?
If you’re asking, “Can I use a deep cycle battery for Livescope?”, the answer lies in understanding why deep cycle batteries are the go-to option for serious anglers. Here’s why they make a great match for your Livescope setup:
1. Consistent Performance
Livescope is a powerful fish-finding tool that delivers real-time sonar imaging, but to function properly, it requires a consistent power source. Deep cycle batteries provide steady power output without fluctuations, ensuring that your Livescope runs smoothly throughout your fishing trip.
2. Extended Run Time
When fishing, you might spend hours or even a full day on the water. Deep cycle batteries are designed to provide power over an extended period, unlike starting batteries which are made for quick bursts. With a deep cycle battery, you won’t have to worry about your Livescope losing power midway through your outing.
3. Battery Longevity
Deep cycle batteries are built to be discharged and recharged frequently, which makes them perfect for powering equipment like Livescope. While traditional batteries may degrade quickly with frequent use, deep cycle batteries are made to withstand this, meaning you’ll get a longer lifespan out of your battery investment.

How to Choose the Right Deep Cycle Battery for Livescope
Now that we’ve established that you can use a deep cycle battery for Livescope, let’s look at how to choose the right battery for your specific needs.
1. Battery Capacity
Battery capacity, measured in amp-hours (Ah), is an important factor to consider when selecting a deep cycle battery for Livescope. A higher amp-hour rating means the battery can provide more power over time. For Livescope, it’s recommended to use a battery with at least 30-50 Ah capacity, depending on the length of your trips.
2. Type of Deep Cycle Battery
There are different types of deep cycle batteries available, including:
- Flooded Lead Acid Batteries: These are the traditional deep cycle batteries, known for being cost-effective. However, they require regular maintenance and are heavier.
- AGM (Absorbed Glass Mat) Batteries: These are sealed, maintenance-free batteries that offer better performance and faster charging times. They are more expensive than flooded batteries but provide superior durability.
- Lithium-ion Batteries: While these are the most expensive, lithium-ion batteries offer the best performance, lightweight design, and longer lifespan. For anglers who want the best in terms of power and weight, lithium-ion deep cycle batteries are an excellent choice for Livescope.
3. Size and Weight
Consider the weight and size of the battery, especially if you’re limited on space or concerned about the overall weight of your boat. Lithium-ion deep cycle batteries are much lighter than AGM or flooded lead-acid batteries, making them ideal for reducing the overall weight of your setup.

Benefits of Using a Deep Cycle Battery for Livescope
Using a deep cycle battery for Livescope comes with a variety of benefits. Whether you’re a weekend angler or someone who fishes competitively, having the right power source can make all the difference.
1. Reliable Power
When you’re out on the water, the last thing you want is for your Livescope to suddenly lose power. Deep cycle batteries are designed to provide consistent and reliable power for long durations, so you can focus on fishing without worrying about battery life.
2. Reduced Downtime
With a deep cycle battery, you don’t need to recharge as frequently, which means less downtime and more time fishing. Whether you’re out for a full day or multiple days, a properly charged deep cycle battery will ensure your Livescope remains powered.
3. Cost-Effective Over Time
Although deep cycle batteries, particularly lithium-ion, may be more expensive upfront, they tend to last much longer than traditional cranking or starting batteries. This means you won’t have to replace them as often, saving you money in the long run.

FAQs
1. Can I use a car battery for Livescope instead of a deep cycle battery?
Technically, you can, but it’s not recommended. Car batteries are designed for short bursts of high energy to start an engine, not for continuous power output over long periods like deep cycle batteries. For reliable performance, a deep cycle battery is the better choice for Livescope.
2. What is the best type of deep cycle battery for Livescope?
The best deep cycle battery for Livescope depends on your needs. AGM batteries offer good durability and maintenance-free use, while lithium-ion batteries provide the best performance and lifespan, though at a higher price.
3. How long will a deep cycle battery power my Livescope?
This depends on the amp-hour rating of the battery and how much power your Livescope draws. A battery with a higher Ah rating will last longer. On average, a 30-50 Ah battery should power Livescope for an entire day of fishing.
4. Do I need to charge my deep cycle battery after every use?
Yes, it’s recommended to charge your deep cycle battery after each use to ensure it remains in optimal condition and provides consistent power during your next outing.
5. What size deep cycle battery is best for Livescope?
A battery with at least 30-50 Ah is recommended for Livescope to ensure you have enough power for a full day on the water.
Conclusion
So, can I use a deep cycle battery for Livescope? Absolutely! In fact, using a deep cycle battery is one of the best ways to ensure that your Livescope system has a steady and reliable power source while you’re out fishing. By choosing the right type of battery, such as AGM or lithium-ion, and considering factors like capacity and weight, you can enjoy longer run times and more productive fishing trips.
