Use and maintenance of lead-acid batteries
Lead-acid batteries, also known as batteries, are in the form of emergency lights in rural areas. They are often made of glass or plastic and use lead dioxide and lead plates as the positive and negative electrodes of the battery, and sulfuric acid as the main electrolyte. Because many farmers' friends do not understand their chemical principles and use them improperly, the lifespan of emergency lights has been greatly shortened, and they have been abandoned in a short time, which has caused both waste and environmental pollution. In fact, as long as the correct use of methods, the emergency lamp life is generally up to 3-5 years, or even longer. The correct method of use is: 1. The newly purchased lead-acid battery emergency lights should be fully charged before use. Because many emergency lights have been on hold in stores for months or even more than half a year, they must be fully charged before use. 2. When used, especially when the lights are continuously dark for a long time, they must be charged immediately. 3, each charging time is generally 12-15 hours, not enough electricity immediately after use, need to stand for a few minutes, so as not to burn high-voltage beads. 4. After using for a period of time, check whether the liquid level of the solution is lower than the internal electrode plates of the battery and the insulating asbestos. When the temperature is lower than that, the cold water must be added in time, and sulfuric acid must not be added. There are two reasons: First, the concentration of sulfuric acid repurchased by the market is different from the concentration in the emergency lights; second, the loss of sulfuric acid during use is relatively small, but it has only been converted into lead sulfate. Be especially careful when adding cold boiled water. Do not spill sulfuric acid water. 5. If it is not used for a long time, it should be fully charged, stored in a cool and cold place, checked once every two months, and be fully charged. It is forbidden to leave it without electricity. 6. For lead-acid batteries that have been ineffective for a long time, do not throw them at random and hand them over to the waste collection station for proper disposal. Because sulfuric acid and lead pollute the environment.
