1) It is recommended that the battery be used at the temperature of+5 ℃~+30 ℃ (better than 25 ℃). High temperature will shorten the life and low temperature capacity

2) It is strictly forbidden to mix batteries of different brands, different capacities and different old and new ones

3) The battery will produce hydrogen in use, so keep away from fire sources, keep ventilated and prevent explosion

4) Please keep the environment clean, too much dust may cause short circuit of the battery

5) After the battery is discharged, it should be recharged in time. If the battery is not fully charged, the battery capacity will be reduced or even damaged, so it must be equipped with a suitable charger

6) If the load of UPS is too light (such as 1KVA UPS with 150VA load), it may cause deep discharge of the battery, which should be avoided as far as possible

7) Proper discharge is conducive to the activation of the battery. If the mains supply is not stopped for a long time, the battery should be discharged manually 2 to 4 times a year. The current load can be used to discharge for 1/4 to 1/3 of the backup time

8) The battery (UPS) that has been out of service for a long time shall be charged and stored, and the battery shall be charged and discharged once every six months. Generally, the battery shall be float charged for about 4~10 hours, and it shall be operated for 2~3 minutes under the inverter state of the battery
