Everything You Need to Know About Deep Cycle Batteries

Lithium Battery

Whether you're planning an adventure or updating your commercial equipment, you'll need a battery that can last for long periods of time. However, if you're new to power supplies, it's important to know that any old car battery won't cut it. You'll need to invest in a deep cycle battery.


Deep cycle batteries are specific powerhouses for any vehicle that needs a consistent supply of power. But how do you know what it is you're looking at? Continue reading for everything you should know about deep-cycle batteries, including what they are, how they work, and what aspects to consider before buying one.


What Is a Deep Cycle Battery?

If you've not worked with deep cycle batteries before, you might equate it to the starter battery in your car. However, these types of batteries have different designs and use.

While starter batteries are made to provide a large burst of upfront power, deep cycle batteries are made to provide continuous power for a long period of time. These are critical for applications that need consistent energy while they operate.


Types of Deep Cycle Batteries

A few types of deep cycle batteries exist for different purposes. Among the most common of these batteries include:

  • Flooded lead-acid

  • Gel and AGM

  • Lithium-ion

While popular in older vehicles, we're seeing the use of flooded lead-acid batteries wane in favor of AGM and lithium-ion. Their propensity to leak and heavyweight makes them an outdated option for most operations.


AGM batteries work similarly to flooded ones without free-flowing liquid. This makes them ideal for situations in which the battery could tip over. However, these batteries are also heavy and without proper maintenance, have a short lifespan.

Lithium-ion batteries use a unique design that charges differently than their lead-acid counterparts. Lithium-ion deep cycle batteries require no maintenance, are lightweight, and can discharge much deeper without affecting their lifespans. While they are the most expensive option, they pay for themselves in the long run.


What are Deep Cycle Batteries Used For?

People use deep cycle batteries for applications that need a consistent supply of power to operate. You'll commonly find deep cycle batteries in:

  • Golf carts

  • Scissor lifts

  • Wheelchairs

  • Forklifts

  • Recreational vehicles

  • Boat motors

  • Off-grid energy systems


How to Charge Deep Cycle Batteries

Not all deep cycle batteries charge the same. Depending on whether you use lead-acid or lithium-ion, you'll want to know how to properly charge your battery.

For optimal lead-acid charging, you should use a constant voltage charging technique. This provides an uninterruptible supply of low current power, assuring the battery stays topped off. Ideally, you'll want your AGM battery to float charge with this method.


Lithium-ion batteries have a design that allows them to take more current in a charge. This allows them to charge much quicker. For lithium batteries, you don't have to keep a consistent voltage to protect their lifespan. 


Best Deep Cycle Battery for You

Choosing a deep cycle battery depends on a few aspects. You'll want to consider charging capabilities, uses, and cost when choosing the right deep cycle battery for you.
