Lead-acid batteries are widely used in automobiles, inverters, spare power systems, etc. Different from tubular and maintenance-free batteries, lead-acid batteries require appropriate maintenance and maintenance to extend their life. The lead-acid battery consists of a series of electrode plates immersed in a sulfuric acid solution. These panels have a grid attached thereon. The plate is divided into a positive plate and a negative electrode plate. The positive electrode plate contains pure lead as an active material, while the leads of the lead attached to the negative plate. BeIn order to connect, all positive electrode plates are connected in series, and one end is exposed as the positive terminal. Also, all negative plates are connected together and connected to the negative terminal. Starting or starting also known as SLI (starting light ignition) battery, providing large current to start the car and engine in the generator. They have more plates compared to other lead-acid batteries. The deep circulation battery is designed for many charging / discharge cycles and has a thick plate. Be
The charged battery can release its current when connected to the load. During the discharge process, sulfuric acid is bonded to the active material on the positive electrode and the negative electrode plate, resulting in a lead in which sulfate is formed. During this process, the hydrogen atom from sulfuric acid is reacted with oxygen to form water. This causes electrons to release from the positive electrode plate, which will be accepted by the negative plate. This results in a potential at both ends of the battery. The electrolyte in the lead-acid battery is a mixture of sulfuric acid and water having a specific specific gravity. The specific gravity is the weight of the acid-water mixture compared to the equal amount of water. The proportion of purely ion water is 1.
Inside the battery, there are some battery cell arrays called a battery. In a 12 volt battery, there are six batteries, and the rated voltage of each battery is 2 volts. The current transmission capacity of lead-acid batteries is usually expressed as AH (ampere hours). A AH is equal to 3600 coulomb charge. AH is the ability of the battery to provide 1 ampere current within 1 hour. Therefore, a 100ah battery can provide 1 ampere current for 100 hours. The battery is based on the discharge rate of the load based on a specific time. For example, a 100ah battery is discharged for 20 hours at a rate of 5 amps. Battery cycles are defined as a complete discharge and charging cycle. This cycle is usually discharged from its 100% charge to 20% charge, and then discharges from 20% to 100%. If the battery is discharged and charging regularly, the battery can be healthy. Depth discharge to 50%, then charge it to 100% again every day, will increase the battery life. Therefore, it is preferred to discharge and charge the inverter and emergency cells every day or at least every two days. Start the car battery daily and charge it to extend its service life. Be
Water is another important aspect of battery maintenance. A drastic chemical reaction occurs when the battery is discharged and charging, and heat is generated. This will evaporate the water inside the battery, and the specific gravity of the electrolyte changes. Therefore, if the water level is reduced to the desired water level, the battery must be added to the battery using an excluding distilled water. Do not add too much water because it may short the battery pole plate. If the battery is not used, 4% of self-discharge occurs every week. For example, if it is not allowed to discharge through the load, the 125ah inverter battery will discharge from 5 amps per week. Be
In order to keep the battery well, battery balance must be performed. Due to aging, all batteries are charged uneven, some batteries are charged quickly, and other batteries are slow. Balance can be completed by slightly charged the battery to make the weaker battery are also charged. The terminal voltage of 12 volt car batteries is 13.8 volts, while the battery voltage of 12 volt tube is 14.8 volts.
Vulcanization is another factor affecting battery efficiency. During the discharge process, primary sulfate will be formed, which will accumulate on the plate. This prevents charge release and acceptance. However, these sulfate transistors will be removed during water injection and charge, so it is preferred to charge immediately after filled with water. If the lead accumulation of sulfate is too much, desulfurization devices must be used for desulfurization (which provides current pulse to remove sulfate crystals). It is also possible to remove sulfate by removing the electrolyte from the battery and then purge the fresh acidic water with distilled water.
