What are the important parameters of UPS battery?

1. UPS battery capacity: It is stated in Ah (Ampere hour) that 1Ah is the current that can reach 1A. Generally, the larger the UPS battery, the higher the capacity. 2. Nominal voltage: When the UPS battery just leaves the factory, the potential difference between the positive and negative electrodes is called the battery's nominal voltage. The nominal voltage is determined by the electrode potential of the plate material and the concentration of the internal electrolyte. When the ambient temperature, time of use, and working conditions change, the output voltage of the unit UPS battery changes slightly. In addition, the output voltage of the battery has a certain relationship with the remaining power of the battery. 3. Internal resistance: The internal resistance of the battery contains ohmic internal resistance and polarization internal resistance. The internal resistance of the UPS battery is determined by the resistance of the plates and the resistance of the ion current. During the charging and discharging process, the resistance of the electrode plate is constant, but the resistance of the ion current will change with the change of the electrolyte concentration and the increase or decrease of the charged ions. 4. Charge stop voltage: When the UPS battery is sufficiently charged, the active material on the electrode plate has reached the saturation condition, and then continue to charge, the battery voltage will not rise, the voltage at this time is called the charge stop voltage. 5. Discharge stop voltage: The discharge stop voltage refers to the lowest voltage allowed when the battery is discharged. If the battery continues to discharge after the voltage is lower than the discharge stop voltage, the voltage at both ends of the battery will drop rapidly, forming a deep discharge. In this way, the product formed on the electrode plate is not easy to recover during normal charging, which will affect the life of the UPS battery; The discharge stop voltage is related to the discharge rate. 6. Energy. The energy of a UPS battery refers to the electrical energy that the battery can give under a certain discharge system, usually stated in watt-hours (Wh). 7. Storage function. During storage of the battery, because there are impurities in the battery, such as positive metal ions, these impurities can form a micro-battery with the negative active material, causing the dissolution of negative metal and the separation of hydrogen.
