Collection: What Are Deep Cycle Batteries: A Handy Guide for Shoppers

When it comes to function, a deep-cycle battery supplies less power in a continuous stream, unlike traditional car batteries, which provide short concentrated bursts of power to help kickstart the vehicle. This difference led to dual battery systems for boats and RVs. In a dual battery system, your car battery starts your engine, and your deep-cycle battery runs your essential appliances inside the vehicle. 

There are several types of these batteries as well. First is the flooded deep cycle lead-acid batteries, one of the oldest types of batteries in the market. They are sometimes referred to as "wet cells" since they have liquid electrolytes inside, meaning these batteries must always stay upright. Overall, they are on the heavier side and require the most maintenance, causing their popularity among consumers to gradually decline. 

The next type is the Valve-Regulated Lead-Acid (VRLA) Gel and AGM batteries. They display a significant improvement compared to flooded batteries, and in case of overpressure during charging, both have a safety valve that opens to release the build-up. The distinguishing factor between the two is that gel deep cycle batteries use a gelled electrolyte. In contrast, AGM deep cycle batteries use an electrolyte absorbed in glass matt.

We also have lithium-ion batteries. These are quite promising as they are powerful, fast-charging, and can be discharged more deeply without reducing lifespan. While lithium-ion batteries are generally good performance-wise, many are hesitant to go for them because of their reputation for catching fires and explosions.

Lastly, we have the famous LiFePO4 batteries. These lithium deep-cycle batteries boast enhanced safety, higher capacity, and improved discharge and charge efficiency. Packed in a lightweight, compact form, these are perfect for outdoor adventures like camping and road trips. 

Now that we have answered the basics of "what are deep-cycle batteries?", let's delve more into the characteristics of this premium power pack, the applications they are suited for, and when you can get the best deep-cycle batteries at great prices. 

How Long Do Deep-Cycle Batteries Last?

Ah, one of the most common questions of potential battery buyers online: How long do deep-cycle batteries last? On average, deep-cycle batteries have a service life of up to 6 years with proper usage and maintenance. Lithium deep-cycle batteries, like LiFePO4 batteries, last even longer and can even reach a decade of lifespan.

Part of this is due to its built-in battery management system (BMS), which increases protection against overcharging, over-discharging, overheating, and short circuits. Despite this, several factors may still affect a deep-cycle battery's life, such as frequent full discharges and using an inappropriate charger to top off the power pack. 

On the bright side, there are ways to extend a deep-cycle battery's lifespan. For one, give your batter a chance to completely charge using the appropriate deep cycle battery charger and avoid partially recharging it. This will allow the battery to undergo a conditioning phase that helps prevent damage to its plates. 

Additionally, while deep-cycle batteries can function at an 80% discharge level, it's a good idea to avoid letting them drop to this point daily. Remember that slow charging is best for this battery type, and keeping it fully charged before storing it will help keep it in good shape.

What Are Deep-Cycle Batteries Used For?

As mentioned above, deep-cycle batteries are highly versatile. The extra runtime from their higher depth of discharge rate is extremely handy in several applications, whether at home or exploring the great outdoors. 

Here's where you can use these premium power packs: 

Energy Storage

The longevity of deep-cycle batteries makes them the perfect energy storage system. Integrating a deep-cycle battery into your solar power system can maximise the energy you generate from the sun, especially during peak hours. It's convenient, cost-effective, and eco-friendly—what's not to love?

Camping

If you search "deep-cycle battery camping" online, you'll get many suggestions on what power pack to buy. That's how popular these batteries are in the camping field. After all, who wouldn't want to have their essential appliances run for an extended period? Moreover, deep-cycle batteries are also famous for their fast-charging capability, making them ideal for those who are always on the go. 

Home Backup

A home backup battery must run primary appliances until the power comes back. This is definitely a job for a deep-cycle battery, as it can effectively run even power-critical electronics like refrigerators and medical equipment. For best results, go for a lithium deep-cycle battery for maximum reliability, longevity, and power quality. 

Marine

If there's one thing deep-cycle batteries are masters of, it's serving as boat batteries. No one wants to deal with a power shortage while sailing, so these power packs are sure to shine here. There are even slim deep-cycle batteries perfect for a boat’s narrow interior!

In fact, deep-cycle batteries are highly recommended for boats along with a starter battery since they serve as the secondary power pack responsible for running your electronics on board. This way, you effectively crank your engine and ensure you have ample power from a separate battery to power your essentials. 

RVs and 4x4s

Ask RV owners, "What are deep-cycle batteries?" and most will go on about how useful these power packs are. It's basically the same concept as boat batteries—an RV or 4WD needs a dual battery system consisting of a starting battery for the vehicle engine and a deep-cycle battery for running electronics. This is particularly important for road adventurers who stay out for several days. 

Industrial Applications

If there's a deep-cycle battery for camping, there is also one for the worksite. That's right, these power packs are terrific for both work and fun times. Packing enough output to run power tools is a must-have in job sites, especially those located in areas prone to power outages. 

Off-grid

Whether you're looking to reconnect with nature for a few days or aiming to relocate off-grid permanently, bringing a deep-cycle battery will do wonders for your experience. This will allow you to tackle everyday in comfort, with everything you need smoothly running such as your fridge, cookers, and heater/AC. 

Have we answered, "What are deep-cycle batteries used for?" By now, we're guessing you're looking for stores to buy one, so keep reading. We'll discuss where to get the best deep-cycle batteries to help you make the most of your money.

Where To Get Good Deep-Cycle Batteries?

Time to go shopping for the perfect deep-cycle battery. Of course, we're starting with the stores. Now, deep-cycle batteries are available both online and in physical stores at varying prices. If you are to choose yours, we recommend going for a lithium deep-cycle battery like a LiFePO4 to ensure the best quality. Fusing the longevity of a deep-cycle battery with the many advantages of lithium iron phosphate battery such as increased protection will give you a power pack well-equipped for wherever you need to use it. 

However, one possible downside of this would be the price. LiFePO4 batteries are known to be expensive. You can get them for cheaper price tags in certain stores, but you need to take great care when going for affordable deep-cycle batteries since you could end up with an inferior-quality power pack. While it may be tempting to initially save a few bucks on a deep-cycle battery, this may not be the case long-term and may even result in more payments.
