Selecting a good battery can be challenging for everyone. Whereas all batteries claim to be well suited for energy storage purposes, there are only few best 12V deep cycle batteries that will give you top performance. To begin with, deep cycle batteries use chemical reactions inside the battery to develop voltage which then powers your equipment. These batteries are designed to discharged and recharged several times. Unlike the conventional car batteries that produce bursts of electrical energy for short periods of time, deep cycle batteries deliver steady power over long periods of time.
There are several types of deep cycle batteries available depending on the technology they are made with. These include; gel batteries, flooded batteries, lithium-ion batteries and Absorbent Glass Mat (AGM) batteries. The flooded battery is the most common of these and resembles the lead acid batteries used in motor vehicles. The gel batteries use a gel-like electrolyte while the AGM batteries are designed with a glass mat separator between the acid and the plates. The Lithium-ion batteries are however newer and therefore are not as popular as the other three types.
Because deep cycle batteries are quite expensive and have a variety of applications than the standard lead acid batteries, you’d want a battery with reliable performance with proven durability. There are a lot of factors that you will need to consider before choosing a deep cycle battery that can best serve you such as:
- Cycle rating
- The number of times the battery can be discharged and recharged and Amp hours
- The rated capacity of chemical energy stored inside the battery that can be converted into electrical energy. It also refers to the total amount of energy the battery can store.
