Comparison of 12V Deep Cycle Batteries

This article is a comparison of 12V deep cycle batteries and the powerful energy problem is described at first for easy reading.

BUT! Before we jump into the technical details let’s first clear all of the doubts related to cycle and battery power measurement.

So, let’s start with the basics Whenever you will see the word cycle, it means a full discharge and recharge of a battery, but wait, what is full discharge??

It is the capacity to which a battery can be fully utilized if you mean that is zero volts then NAH! Different batteries have their minimum discharge point and if fully charged battery voltages drop down to that minimum level we call it one battery cycle. For simplicity reasons, people usually describe the battery time with the of years it will work. However, it is not the case that the battery life, in technical terms, can only be measured by the number of full discharge/charge cycles it is capable of performing.

Another hot word in the world of batteries and charge storing devices is DOD  (depth of discharge) depth of discharge tells about the capacity that is being utilized during one cycle. If you observe the above mention graph you can easily see that if the DOD is around 50 percent then the battery can perform 1000 cycles.

Now you know the basics so let’s jump into the real business  DEEP CYCLE BATTERIES

If you’ve spent any time shopping for batteries for your electric wheelchair or other equipment, you’ve probably noticed that some batteries are labeled as “deep cycle” batteries, while others are not. The difference between these batteries is extremely important to understand if you want a reliable battery experience. Here’s what you need to know:           

Deep cycle batteries have the characteristic of handling very low discharge cycles (90 to 95 percent) without any compromise in their expected average cycles.

Deep cycle batteries look a lot like any other battery, as their outer case is very much like simple lithium-ion batteries it is quite difficult even for the specialist to differentiate them by just looking. However, internally they are a lot different from their lower class competitor like lithium or lead ion batteries.

Types of deep cycle battery

There are many types of batteries available out on the market and it is quite a tedious task to differentiate between them and select one that can perfectly perform well for your appliance.

For example, the sealed lead acid batteries in which the electricity is generated in the parallel plates submerged in the acid. On the other hand, in the case of high-rate batteries, there are small compartments carrying very small electromagnetic plates for quick generation of energy. If we talk about deep cycle batteries, the electrolytic plates are very thicker in size as compared to any other type of battery available.

For example, a high-rate battery, because the energy-inducing chemical reaction goes into the plate and therefore needs to be thick to be able to handle the reaction. If the internal plates are thin, on continuous deep cycling of full charge and discharge the plate gets heat up due to the movement of electron and this heat damages the plates and eventually, battery dies but just by making the plates thicker, they get the ability to hold up to multiple deep discharges over time. 

Deep cycle lifepo4 batteries

Deep-cycle lifepo4 batteries are sealed plus they require minimum to zero maintenance lifepo4 deep-cycle batteries have the ability to deliver superior power in demanding renewable energy applications. Deep moreover they can provide rugged durability and are mostly preferred in outdoor projects for example wind turbines or hybrid wind and solar projects because of their outstanding performance and long battery life, not only this they come up in different designs and are easily available in all parts of the world.

Lead alloy grids provide longer shelf life and superior corrosion resistance as well as deliver more concentrated energy to the terminals. Its premium grade, double-insulated separators allow maximum charge flow between the plates for optimum performance.

In addition, I will talk about some basic knowledge of gel batteries below. Deep cycle gel batteries use a special kind of substance that, when an electron passes through it and make the substance temperature goes high a bit, into a thick gel, therefore making it The gel is better at heat distribution and off-gassing, and therefore has better performance throughout its life.

However, the deep cycle battery is an advanced lifepo4 battery that provides superior power to support the higher electrical demands of today’s RV, camper and trolling motor, and so on applications.

Next, Looking the most popular voltages available in comparison to 12v deep cycle batteries are 12V deep cycle batteries
