What are the factors that affect the service life of UPS power batteries?

Important factors affecting the battery life of UPS power supply 1. Too high ambient temperature will cause gas to be generated during battery overcharging. If the ambient temperature is too low, the battery will be undercharged, which will affect the battery life. Therefore, the ambient temperature is generally required to be around 25°C, and the UPS battery float voltage value is also set according to this temperature. In practical applications, the battery is generally charged within the range of 5°C to 35°C. Lower than 5°C or higher than 35°C will greatly reduce the capacity of the battery and shorten the service life of the battery. 2. The deeper the discharge depth of the battery, the fewer the number of cycles it uses. Therefore, it is necessary to prevent deep discharge during use. Although Shante UPS power supply has a battery low-potential protection function, generally when a single battery is discharged to about 10.5V, the UPS will automatically shut down. However, if the UPS is under light-load discharge or no-load discharge, it will also cause deep discharge of the battery. The so-called depth of discharge refers to the percentage of the battery's standard capacity that accounts for 90% of its standard capacity when the user uses the battery pack to discharge the battery. 3. Before putting it into use after installation, the remaining capacity of the battery should be judged according to the open circuit voltage of the battery, and then different methods should be used to supplement the battery. Sante batteries that have been left on standby shall be recharged every 3 months. The open circuit voltage of the battery can be measured to judge the quality of the battery. Take a 12V battery as an example. If the open circuit voltage is higher than 12.5V, it means that the battery has more than 80% energy storage. If the open circuit voltage is lower than 12.5V, it should be charged immediately. If the open circuit voltage is lower than 12V, it means that the battery stores less than 20% of the electric energy and the battery is unusable. 4. For example, a 100AH u200bu200bbattery, Cu003d100A. The optimal charging current of lead-acid maintenance-free batteries is about 0.1C, and the charging current cannot be greater than 0.3C. Excessive or too small charging current will affect the service life of the battery. The discharge current is generally required to be between 0.05C and 3C. UPS can meet this requirement in normal use, but it is also necessary to prevent accidents such as short-circuit of the battery. 5. Because the UPS battery is a standby mode of operation, the mains is in a charging state under normal conditions, and will only be discharged when the power fails. In order to prolong the service life of the battery, UPS chargers are generally controlled by constant voltage and current limiting. After the battery is fully charged, it will turn to a floating state, and the floating charging voltage of each cell is set to about 13.6V. If the charging voltage is too high, the battery will be overcharged, otherwise the battery will be undercharged.
