The plates of ordinary batteries are made of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. Its important advantages are stable voltage and low price; its disadvantages are low specific energy (that is, the electric energy stored per kilogram of battery), short service life and frequent routine maintenance. Dry-charged battery: Its full name is dry-charged lead-acid battery. Its important 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. Just add electrolyte and wait for 2030 minutes to use. 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. There are also two types of maintenance-free batteries on the market: the first is to add electrolyte once at the time of purchase, and then do not maintain it during use (add supplementary fluid); the other is that the battery itself has been filled with electrolyte and sealed when it leaves the factory. The user cannot add refill at all. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
