Analysis of the types and daily maintenance of lead-acid batteries

A storage battery is a kind of battery, and its purpose is to store a limited amount of electric energy and use it in a suitable place. Its operating principle is to convert chemical energy into electrical energy. The so-called battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary. Lead-acid batteries commonly used in us are divided into three categories, namely general batteries, dry-charge batteries and maintenance-free batteries. 1. General storage battery; the plate of the general storage battery is composed of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. Its key advantages are stable voltage and low price; its disadvantages are low specific energy (ie, electric energy stored per kilogram of battery), short service life and frequent routine maintenance. 2. Dry-charged battery: its full name is dry-charged lead-acid battery. Its key feature is that the negative plate has a high power storage capacity. In a completely dry state, it can save the obtained power within two years. At the time, just add electrolyte and wait for 2030 minutes to use. 3. Maintenance-free storage battery: Due to its structural advantages, the maintenance-free storage battery consumes very little electrolyte, so do not add distilled water during the service life. It also has the characteristics of shock resistance, high temperature resistance, small size, and small self-discharge. The service life is generally twice that of ordinary batteries.
