If you are like most people, you probably do not give much thought to the batteries that provide power to the equipment and devices you use on a daily basis. For instance, you have probably not considered how the batteries for your key fob differ from one that is used to give energy to an all-terrain vehicle. You also not may not know the answer to the question, "What is a deep cycle battery?"
A simple fact is that all batteries store energy that can then be transferred into the power needed by the devices we use. However, the different types of batteries available to you can differ greatly in the ways they work, so it is important to understand why some batteries are more important for certain applications than others.
Deep cycle batteries will oftentimes look like a car battery to people who are unfamiliar with them. However, the two battery types are pretty different. Deep cycle batteries are lead batteries specifically designed to provide long-term energy to the objects powered by the battery. These types of batteries are rechargeable and will usually operate effectively until 80% of the energy they have stored is depleted. The deep cycle battery gets its name from the extra-thick plates it possesses that allow it to endure more discharge cycles than other types of batteries.
The sustained energy provided by deep cycle batteries is perfect for applications that favor a long-term energy supply over a battery that provides a quick start. If you are a boat owner, it is likely you use a deep cycle battery to power your craft. Many consider it to be the best boat battery. Other deep cycle battery uses include:
Hybrid batteries are sometimes used and are most popular for marine applications. Hybrid batteries provide sustained power that is the norm for deep cycle batteries but also deliver the added benefit of a starter burst. However, hybrid batteries will not last as long as a deep life battery specifically designed for longevity in most cases. Let''s look at the most commonly used deep cycle batteries: the flooded and deep valve battery types.
The first type of deep cycle battery is a flooded deep cycle battery. These are not very different from the standard lead-acid car batteries. This battery is currently referred to as a “wet-cell” battery and is the oldest and most commonly used deep cycle battery type.
Flooded batteries will require more maintenance than other battery types due to the liquid contained within the batteries. Flooded deep cycle battery owners will need to refill the battery’s liquid container with distilled water when the electrolyte levels inside the battery are low.
The next answer to the question "what is a deep cycle battery?" is the valve regulated deep cycle battery. This is also commonly referred to as a sealed lead-acid battery and does not possess the need to be watered. Sealed batteries do not require the maintenance that is necessary with other types of batteries but should still be routinely monitored.
The “recombinant” feature of the battery signifies that both oxygen and hydrogen are present within the battery. The valve possessed by this deep cycle battery type is activated when the high voltage is used to recharge the battery. When the valve is activated, materials inside the battery make an exit and the battery capacity is decreased. The two types of valve regulated deep cycle batteries available are the AGM and gel varieties.
Individuals searching for information on how to charge a boat battery should first understand the need to ensure the battery is dust- and corrosion-free. You should also make sure the battery charger you buy is capable of providing the amperage your deep cycle battery needs in a time frame that is acceptable. A charger that is not well-suited for your battery will not provide you with an adequate charge for your boat battery and may do damage to it.
One common rating that will help consumers decide the best boat battery for them is “amp hours.” This rating informs battery users of how much amperage is available to them during one complete hour of battery usage. Amp hours for deep cycle batteries measure the capacity for the chemical energy that exists within the battery to be converted to electrical energy. An amp hour rating will also provide users with a measure of how much battery usage they can enjoy before a recharge is necessary.
It is important to understand that many manufacturers choose to measure the life span of their batteries by cycles and not solely in calendar years. A cycle represents a single and complete discharge of a battery. The manner in which your battery is used, charged, and maintained will affect the amount of use you enjoy per cycle.
When performing your calculations, you should remember that it is never a good idea to allow a 100% discharge of your deep cycle battery as you will have an even greater need to know how to charge a boat battery. The specific life span you can expect will be ultimately determined by your usage habits and other factors particular to your unique situation. However, you can ensure you enjoy maximum possible battery life by properly maintaining your battery. You should provide water as needed and adhere to the recommendation that your battery is never discharged by more than 50%.
You should also use a charging system that is appropriate for your battery. A deep cycle battery is designed to provide a steady supply of energy over an extended period of time.

A deep-cycle battery is a battery designed to be regularly deeply discharged using most of its capacity. The term is traditionally mainly used for lead–acid batteries in the same form factor as automotive batteries; and contrasted with starter or cranking automotive batteries designed to deliver only a small part of their capacity in a short, high-current burst for starting an engine.
For lead–acid deep-cycle batteries there is an inverse correlation between the depth of discharge (DOD) of the battery and the number of charge and discharge cycles it can perform;[1] with an average depth of discharge of around 50% suggested as the best for storage vs cost.[2]
Newer technologies such as lithium-ion batteries are becoming commonplace in smaller sizes in uses such as in smartphones and laptops. The new technologies are also beginning to become common in the same form factors as automotive lead–acid batteries, although at a large price premium.[3]
The structural difference between deep-cycle and cranking lead–acid batteries is in the lead battery plates. Deep-cycle battery plates have thicker active plates, with higher-density active paste material and thicker separators. Alloys used for the plates in a deep-cycle battery may contain more antimony than that of starting batteries.[4] The thicker battery plates resist corrosion through extended charge and discharge cycles.
OPzS stands for German ortsfest Panzerplatte, Säure, stationary tubular plate, acid.[6]
OPzS batteries are a type of deep-cycle battery commonly used for backup power systems and renewable energy applications.[7] OPzS is recommended for storing energy from intermittent supplies, such as wind and solar supplies for off-grid use.
OPzV stands for ortsfest Panzerplatte, verschlossen, meaning stationary tubular plate, sealed.[6]
OPzV batteries are very similar to OPzS batteries, with the only technical difference being that OPzV batteries are sealed. OPzV batteries are relatively maintenance-free, while OPzS batteries require the occasional top-up with distilled water.[8]
Although still much more expensive than traditional lead–acid, a wide range of rechargeable battery technologies such as lithium-ion are increasingly attractive for many users.[citation needed]
BCI says that, industry wide, there is a greater than 98% rate of recovery on all lead acid batteries sold in the United States, resulting in a virtually closed manufacturing cycle.[9]
