When the machines and appliances in your life are running as they should, you may not stop and think too much about the batteries that power them. However, that will be the first place you check as soon as they malfunction.
That’s why it helps to know about the different types of batteries available, and how they work. Today, we’re taking a closer look at deep cycle batteries. In short, these are lead batteries that are designed to deliver sustained power over an extended period of time.
Commonly used on boats, golf carts, forklifts, and other types of heavy-duty equipment, these batteries are responsible for some of the most rugged work around. Here are six facts you might not know about them.
1. Deep Cycle Batteries Are Specially Made
At first glance, a deep cycle battery might look a lot like a car battery. It’s large and box-shaped, and usually includes some type of handle on the top for easy maneuvering.
However, a closer look reveals that these batteries are specially constructed to work as they do. Compared to standard vehicular batteries, these have thicker internal plates, as well as more substantial separators. These mechanisms allow the battery to maintain a deeper charge, for a longer time.
While most deep cycle batteries are made of lead, this isn’t always the case. The lithium deep cycle battery market is rapidly expanding.
2. The Discharge Rate Is Critical
A battery’s discharge rate helps users understand how long it will last. It explains how quickly a charge runs through the battery’s circuit, so you can calculate its overall lifespan.
When using deep cycle batteries, it’s important to understand that these tend to last longer than most available alternatives. This means that you can use them for a substantial period of time before they need to be recharged again.
Specifically, most deep cycle batteries are made to run reliably until they reach an 80% discharge rate. This is a major benefit, as most commercial batteries only deliver a short burst of power before they need to be recharged again.
While you can discharge sooner, most manufacturers do not recommend doing so. For instance, discharging a deep cycle battery below 45% could negatively affect its total life. A specially-made deep cycle battery charger is a necessity with this type of equipment.
3. There Are Many Different Types to Know
There isn’t a universal type of deep cycle battery. Rather, there are a few different models, and each serves its own purpose. The four most common types include:
- Flooded deep cycle batteries
- Gel deep cycle batteries
- Sealed deep cycle batteries
- Lithium-ion deep cycle batteries
Let’s take a look at each of these in greater detail.
Flooded Deep Cycle Batteries
Also called flooded lead-acid (FLA) batteries or wet cell batteries, these require consistent maintenance. Electrolytes are applied on top of the battery plates, and essentially “flood” them, hence the name. When in use, water in the electrolytes breaks down into hydrogen and oxygen gas, and water evaporates.
Users must keep a close eye on the battery’s electrolyte levels, and refill them when they reach a certain point. With flooded deep cycle batteries, it’s also imperative to vent the mechanism and keep it upright.
If improperly vented, the hydrogen and oxygen gases in the battery could ignite and pose a safety risk. Moreover, tilting the battery on its side could lead to spillage.
Gel Deep Cycle Batteries
These batteries have a slower discharge rate than some of the others. As such, they have a longer lifespan and typically contain more power. While this is an obvious advantage, keep in mind that these batteries can also be more expensive.
Sealed Deep Cycle Batteries
Unlike FLA batteries, sealed deep cycle batteries do not require any type of electrolyte maintenance. The electrolyte fluid is sealed into the battery, so manual manipulation is not necessary. Other than this nuance, this type of battery works similarly to an FLA battery.
Lithium-Ion Deep Cycle Batteries
As mentioned, lithium batteries are some of the most innovative and impressive models on the scene. These are the best-performing and longest-lasting of the group, but the price point can be constrictive. As these continue to grow in popularity, there are also other tests required to ensure against manufacturer defects.
4. Their Uses Can Vary
There is a range of machines that require a large amount of power over a sustained period of time. These appliances aren’t suited for starter batteries, which are mostly used when quick bouts of power are needed.
Some of the places where you might find deep cycle batteries include:
- Cars and trucks
- Electric golf carts
- Electric bikes
- Electric wheelchairs and scooters
- Boats and other marine vehicles
- Recreational carts and vehicles
- Construction forklifts
- Solar and wind power systems
5. Water Isn’t an Issue
There’s a reason why so many boat owners keep a steady supply of deep cycle batteries on hand! Unlike other kinds of batteries, these don’t lose effectiveness when they get wet.
As such, they’re ideal to use in any type of weather, or on any kind of terrain. Even if they become soaked, they can still deliver sustained, high-quality energy when you need it the most.
6. They Work Off the Grid
Have you been considering embracing homesteading or off-the-grid living? If so, then you’ll need deep cycle batteries in your arsenal of supplies. These batteries power all types of wind and solar systems, as well as other renewable energy solutions.
Whether you’re running everyday lights or a backup generator, they’ll make sure you’re never too far from the power you need. In fact, many schools, healthcare facilities, and other buildings will stock deep cycle batteries just in case their traditional power goes out.
How Will You Use Deep Cycle Batteries?
It’s important to know the types of batteries that keep your everyday life in motion. If you own a car, boat, or any type of vehicle, then you’ve likely seen deep cycle batteries in action.
Now that you know these interesting facts about them, you can leverage their power to run a variety of tools, machines, and appliances! While you’re at it, keep some on hand as emergency backups, too.
