What are the misunderstandings in the use of UPS battery electrolyte

①Add electrolyte at will. Some car owners add electrolyte when they find that UPS battery has insufficient power and electrolyte density decreases. They do not know that this will increase the battery electrolyte density, increase its internal resistance, decrease voltage, and reduce charge capacity. . The decrease in electrolyte density is due to the excessive discharge of the battery during use and the reduction of the stored power. Therefore, when the electrolyte density decreases, the UPS battery should be charged in time. ②Adding distilled water at will Generally, the electrolyte is insufficient, and distilled water should be added, but sometimes the decrease of electrolyte is due to electrolyte leakage. If you do not fully decompose the reason, adding distilled water will reduce the density of the electrolyte and the battery will not work normally. In addition, do not add distilled water after receiving the car, which will cause the battery to discharge by itself, damage the plates, and affect the service life of the UPS battery. ③Ignoring the level of electrolyte to check the lack of electrolyte will cause the electrode plate to sulfide, reduce the charge capacity, and shorten its service life. It is necessary to regularly check whether the height of the electrolyte level is within the specified range. Generally, inspections are performed every half a month in winter and once a week in summer. Regarding maintenance-free batteries that do not need to add distilled water, the height of the electrolyte level should also be checked regularly. ④The liquid level is too high. Some car owners add electrolyte or distilled water above the limit of the electrolyte level. However, if the liquid level is too high, the electrolyte will easily overflow and corrode the poles, resulting in poor contact or damage to the poles. It will also cause excessive internal pressure of the UPS battery and even cause it to explode. The electrolyte accumulated on the battery cover also connects the positive and negative poles to form a loop, which makes the battery self-discharge. ⑤ Excessive density The electrolyte density is an important indicator of the degree of battery discharge, but the original electrolyte density is the premise. If electrolytes of different densities are added, the density of the original electrolyte will increase. Although it can increase the electromotive force of the battery and increase the terminal voltage and charge capacity, but the density is too high, but the battery terminal voltage and charge capacity will be reduced, and the plate will be vulcanized. Etc., thereby shortening its service life. The electrolyte in the battery is made of dilute sulfuric acid and distilled water, and the color is colorless and translucent. The density is generally 1.24-1.30 grams per cubic centimeter. The specific gravity is 12.75-12.85G/CM3 sulfuric acid plus pure water. If the water is consumed during the battery use, just add pure water to charge. For example, the electrolyte of a lead-acid battery is made up of 80% sulfuric acid and distilled water in a certain proportion to form a cubic density of 1.24-1.30g/cm. The specific gravity is 12.75-12.85g/cm3. Some lead-acid batteries (such as motorcycle lead-acid batteries) have to be filled with electrolyte by themselves. Therefore, you must be extra careful when filling and never get into your eyes. If the water is consumed during battery use, just add pure water to charge.
