Discharge requirements of Panasonic UPS battery

Charging and discharging of Panasonic batteries are required. Especially in harsh working environment, temperature control is more stringent. When the ambient temperature is higher than 25 C, the capacity of UPS battery is higher than the rated capacity.



When the ambient temperature is lower than 25 C, the battery capacity is lower than the rated capacity. Capacity varies with temperature. Maintenance personnel must conscientiously adjust the discharge current of the battery according to the actual temperature change, and control the temperature of the battery to keep it in the range of 22 ~35 ~C. High temperature service environment is the main reason that the actual life of Panasonic battery can not reach the design life.



When the temperature of Panasonic UPS battery rises by l0 C, the acceptance of charging current under constant voltage doubles, and the battery life will be shortened by the increase of total cumulative charge. The basic requirement for UPS battery operation and maintenance is that in order to make the battery always fully charged without overcharging, more than 80% of the rated capacity should be released when the battery is supplied to the load alone.



Discharge tester is specially designed for checking discharge experiment, capacity test, battery routine maintenance, engineering acceptance and other DC power load capacity test. Panasonic battery discharge tester uses new PTC ceramic resistance as discharge load, which completely avoids red-hot phenomenon. It is safe, reliable and pollution-free.



The whole machine is controlled by microprocessor, LCD display, Chinese menu. New appearance design, small size, light weight, easy to move. After setting various discharge parameters, the whole constant current discharge process is automatically completed. Intelligence is fully realized. Make the whole discharge process safer. It is especially suitable for battery acceptance, check discharge test and periodic deep discharge occasions.
