Flooded Lead Acid Battery-Introduction and Charging Method
As the technology world is witnessing advancements and developments each day, our lives are getting much better. Thanks to different forms of batteries that are available in the market that now we do not have to think much about remotes as the battery has replaced remotes. Today all the electrical appliances run on battery without giving their users any sort of pain.
Depending upon the uses and the internal chemistries of a battery, you can select the right battery for your gadget. But one of the most commonly used battery is a lead-acid battery. They were invented and introduced in the year 1859 by Gaston Plante. When it comes to the internal chemistry of this battery, they are made up of lead-dioxide cathode, Sulfuric acid solution electrolyte, and a metallic lead anode.
Even today, people like to operate their vehicles, equipment, and other renewable energy systems with rechargeable batteries because of their advantages and uses. You will be astonished to know that approximately half of the world’s battery sales come from rechargeable batteries only. And there are many different batteries that come under the category of rechargeable batteries, but the most widely used and proven is the lead-acid battery.
What is a flooded lead-acid battery?Flooded lead-acid batteries include an electrolyte that keeps moving around in the battery case. When the flooded lead-acid battery is charged, the acid of the battery and the lead plates tend to react in order to store the electricity. These batteries are bound to be placed upright so that the liquid or the electrolyte does not begin to leak from the caps of the batteries that are mounted on its top.
In the solar industry, flooded lead-acid batteries have been fixed as the standard batteries. These batteries are used in forklifts, golf carts, and marine or in other automotive industries. Among the traditional deep cycle batteries, flooded lead-acid batteries are the most common ones. They are also known as wet cell batteries, as they comprise a liquid mix of water and sulfuric acid. It is significant here for you to know that flooded lead-acid batteries last much longer than any other sealed batteries.
However, it is imperative here to highlight that these batteries require more maintenance than any other sealed battery because flooded lead-acid batteries contain liquid. As mentioned earlier, these batteries are required to be oriented and mounted appropriately; otherwise, due to forceful movements, the battery can get damaged. The users must ensure that there should be no excessive shaking of flooded lead-acid batteries.
Since there is a liquid combination present in the flooded lead-acid batteries, they require constant care in order to maintain the accurate levels of the liquid. Also, these batteries might have a reduced lifespan in places where there are extreme climatic conditions. The water inside the batteries may evaporate or freeze; therefore, it is vital to keep these batteries in an area that has a proper source of ventilation.
Irrespective of maintenance and care, flooded lead-acid batteries remain on the top choice when it comes to reserve power applications. In the case of backup power, telecom, utility, and grid energy storage and backup power supplies, flooded lead-acid batteries are widely used. When it comes to these batteries' benefits, they are highly reliable because of their long deep discharge cycles and low cost.
Is a flooded battery a lead-acid battery?Generally, all the flooded batteries contain 1, 3, 4, or 6 separate cells with a series of negative and positive plates, and these plates are drained in the electrolyte. It comprises 35 percent of sulfuric acid water; however, the separators stops the negative and positive plates from coming into contact with each other.
Every series of the cell in the flooded lead-acid battery produces around 2.1 V per cell, which leads to the battery voltage of 2, 6, 8 or 12 volts. The voltage depends on the application of the battery. The plates of the battery differ in construction by its manufacturer.
Wet cell and Absorbed Glass Mat, i.e., AGM batteries, both are considered as lead-acid batteries that contain a liquid solution that leads to a chemical reaction turning into electrons. When these batteries are put in direct contact with the reserve current, they get recharged. Both flooded or wet cell battery and absorbed glass mat battery have their own merits and demerits, which should be taken into consideration before using them. Flooded batteries and their advantages have been discussed above; now, let’s see AGM batteries' composition and advantages.
These batteries have a glass mat separator that moves the electrolyte liquid between the plates of the battery. The design of the material allows the glass to be saturated with the solution. It also keeps the electrolyte in a suspended form. One of the biggest advantages of these batteries is that they are called maintenance-free batteries as they don’t need watering services often. There are no spillage or gas leakages; they tend to perform well than flooded batteries.
How do you charge a flooded lead-acid battery?There is no point of denying in the fact that the correct charging method can improve the performance of the battery along with its lifespan. Therefore, you are required to pay attention to the charging process of the flooded lead-acid battery. In order to make the process hassle-free, battery charging technology has come with a smart charger. It will help the users inputting their guesswork at bay.
Smart chargers assist in maintaining the balance of undercharging and overcharging. These chargers also prevent the problem of gassing and sulfation. However, if you are not willing to invest in a smart charger, then you are required to follow some simple steps that are mentioned down below:
Charge the battery in a ventilated area because hydrogen gas gets generated during the charging process
Before charging, check all the instructions given by the manufacturer regarding the voltage threshold
The plates of the flooded lead-acid battery must be fully drained in the electrolyte solution. Make sure to fill the battery with de-ionized water or distilled water in order to cover the plates
Ensure that you are filling the water to a well-designated level after the charging process because overfilling the battery when it is on low charge can result in acid spillage
