A key component in any kind of renewable energy system that stores electricity is the Deep Cycle battery.
The whole renewable energy system relies heavily on this component and hence, is very critical in nature.
This battery bank provides a constant source of power, even during periods when the photovoltaic system does not produce power or when the grid is down.
Deep cycle batteries have thicker lead plates and produce current for longer periods of time. The thicker battery plates used here resist corrosion even in extended charge and discharge cycles. A Deep cycle battery –Solar, is one that provides storage energy for renewable energy systems such as wind-powered, solar powered etc. A solar deep cycle battery can survive repeated discharges that can be prolonged and repeated.
One has to look into some specific requirements while buying a deep cycle battery. Some of these requirements are highlighted below.
Take a look at the best three deep cycle batteries and a review about their features:What is the System Storage Requirement?
The system storage requirement varies generally with the application and also the area of residence.
What should be the capacity?
Generally, the total capacity of the deep cycle batteries should be such that it can cover twice the longest outage that can be anticipated.
Deep cycle batteries that last a lifetime are generally expensive. But these last quite long. Some batteries even have a lifetime usage of 5 to 8 years.
Size and weight of the battery
An ideal battery should be easy to move. Any battery that is cheap and best, but is very heavy to move is not good. Always get bigger batteries ifhigher capacity is what one is looking for.
Types of batteries
These are always cheaper and are available in different types and sizes. They are good for most of the applications. When there is adequate ventilation for the batteries these become the first choice. Tipping, spillage, and breakage will not be an issue. Maintenance is pretty much hassle-free.
Sealed AGM batteries are usually expensive, with a similar or longer lifetime cycle when compared to the flooded batteries. They become the best choice when the areas have poor or no ventilation and maintenance is an issue.
Apart from the above-mentioned requirements, a few questions need answers. These answers act as a guide while choosing the type and kind of deep cycle battery that is required.
What is your main purpose or use of the battery?
Which type of deep cycle battery will you be using?
Will you be using it for domestic purpose or for use in boats?
A deep cycle RV battery is generally used for providing power to boat equipment. It is a hybrid type and the lifetime is much shorter. A deep cycle battery solar is generally used for domestic purposes and can deal with many recharging cycles.
Here is a small description of the three best deep cycle batteries and their features.

Which one to choose?
When considering a deep cycle battery, always recognize what your needs are.
Larger batteries are required to handle large equipment, whereas smaller ones are required for smaller devices. Essentially, the batteries with higher amperage last longer. The higher the amperage hours, the longer a deep cycle battery lasts.
