What precautions should be taken when using batteries?

What kind of preventive measures to use batteries? The global battery network is a global battery network 1) It is recommended to use batteries of +5°C~+30°C (preferably 25°C). High temperature will shorten the life and reduce the low temperature capacity; 2) It is forbidden to mix different brands, different capacities, different old and new batteries; 3) When hydrogen occurs during battery use, keep it away from fire, keep ventilation and prevent explosion; 4) Keep the environment clean , Excessive dust will cause the battery to short circuit; 5) The battery should be charged in time after it is discharged. If the battery is not fully charged, it will reduce or even damage the battery capacity. Therefore, you must configure an appropriate charger; 6) UPS load is too light (such as 1KVAUPS150VA load) may cause the battery to discharge too deeply, try to prevent it; 7) Proper discharge is conducive to battery activation. If the battery is left in the power supply for a long time, it should be discharged manually, 2 to 4 times a year. The current discharge method can be used, and the discharge time is 1/4 to 1/3 retention time; 8) Long-term failure battery (UPS) is stored after charging, and the battery is charged and discharged once every six months. Under normal circumstances, the battery should float for about 4~10 hours, and run for 2~3 minutes in the battery inverter state.
