What is a deep cycle battery?

Batteries do a lot for us. From powering our cars and trucks to providing reliable energy for our flashlights during power outages, batteries have become an essential part of our lives. However, not all batteries are created equal. Different batteries come in different strengths for different purposes, the most common varieties you'll hear about are deep cycle batteries.


What is a deep cycle battery?

Deep cycle batteries are a type of rechargeable battery that is designed to provide a steady, consistent current of power over a long period of time. Unlike car batteries, which are designed to deliver a large amount of power for a short period of time, deep cycle batteries are designed to be discharged and recharged multiple times without losing their ability to provide a steady power output. They are often used to power golf carts, RV's, marine batteries and electric vehicles. Deep cycle batteries have several advantages over other types of batteries, such as a higher capacity and durability over time. Additionally, deep cycle batteries are more efficient and cost-effective than other types of batteries. In summary, deep cycle batteries are an efficient and cost-effective way to provide a reliable, steady source of power over a long period of time.


How do I know if I have a deep cycle battery?

If you are wondering if you have a deep cycle battery, the best way to find out is to look at its label. Deep cycle batteries are labeled with their purpose, so if the label says deep cycle or deep cycle/starting, then you know that is what you have. Deep cycle batteries are designed to be regularly discharged and recharged multiple times, while other battery types are not. This makes them ideal for applications where they will be regularly used, such as in recreational vehicles and solar energy systems.


What's special about deep cycle batteries?

Deep cycle batteries offer a reliable, consistent power source that is ideal for a variety of applications. By systematically discharging and recharging, deep cycle batteries are designed to withstand multiple cycles and provide the same amount of power for hours or days at a time. Moreover, they can be recharged thousands of times over their lifespan, which makes them a long-term, cost-effective solution.


Types of Deep Cycle Batteries

Lithium-ion Deep Cycle Batteries

Lithium-ion deep cycle batteries are a popular choice for both RV and marine use due to their many benefits. Not only do they provide a lightweight and efficient power source, they also offer higher energy storage relative to their size when compared to other types of batteries. Additionally, these batteries are capable of withstanding adverse weather conditions, which makes them a great option for camping trips and other outdoor activities.


AGM Deep Cycle Batteries

AGM deep cycle batteries deliver a high performance at a moderate price. Their design is such that the electrolyte is held in an absorbent glass mat which allows for much quicker recharge times and improved performance. This, combined with their low self-discharge rate, makes them a great choice for any application that requires a powerful and long-lasting battery. They are also environmentally friendly and maintenance free. AGM deep cycle batteries are becoming increasingly popular for use in RV and marine applications, as they offer a reliable and efficient power source. They are also a great option for backup power systems, as they are able to discharge and recharge quickly and efficiently.


Liquid-rich lead-acid deep cycle batteries

Liquid-rich lead-acid batteries are one of the oldest and most common battery technologies in use today. They are reliable and have a long lifespan, but they do require regular maintenance in order to ensure they remain in working order. This maintenance mainly consists of topping up the electrolyte solution as needed to keep it at the proper level. Failure to do this can lead to significant damage to the battery and a shorter life-span.

It is important to check the electrolyte level after every use and top it off with distilled water as needed. This is usually a fairly straightforward process, but if you are unfamiliar with it, then it is best to consult with a professional. They can inspect the battery and help you determine the proper level of electrolyte solution.


How long can deep cycle batteries be charged when not in use?

Lead-acid batteries are the most common type of rechargeable battery used in vehicles and other applications as it is relatively cheap and can store a lot of energy. Lead-acid batteries can hold a charge relatively well when not in use, but users should be aware that they will lose 10-35% of the battery's charge per month without any intervention, due to the natural process of self-discharge.

In comparison, Lithium batteries are much better in this regard, losing only about 2-3% of their charge per month. This means that, when not in use, a lithium battery will retain more of its charge and users can expect longer periods of time between charges.
