·UPS Battery Selection
The selection of UPS batteries should pay attention to the selected standard machine or a shorter backup time that can be output in a short time and must have a large current. Currently, there are three kinds of commonly used batteries, all of which are lead-acid batteries, and the model of which are the HS (high efficiency plasma coated lead battery), CS (cover-type lead batteries) and M (sealed lead-acid batteries), and sealed lead acid battery is the most common. Electrolyte sealed lead-acid battery is nearly constant and generates no loss. This is because the sealed lead-acid batteries using advanced cathode absorption-type sealing technology. The technology is available to fill the interval time distilled water extended to 5 years. To ensure the security and reliability of the seal battery, and to ask to charge the accumulators when the battery charge can’t be over the maximum allowable charge current. UPS charger current constant voltage charging adopts the classification methods, namely, the initial charge with constant current charging, the charging current limit specified value or one-tenth of the battery rated capacity of the current value. Charge after a certain time instead of constant voltage charging, which is the floating charge.
