　　How to clean lithium ion battery 18650 price dust and how to store it?

　　Under normal circumstances, when overhauling UPS equipment, first replace the fan, check the DC circuit ripple, and then determine whether to replace the capacitor. In addition, the storage temperature of the lithium ion battery 18650 price should not exceed the range of -20°C to +40°C, and good ventilation is required. . Next, I will introduce the detailed content to you.

　　1. Tips for cleaning dust on UPS batteries

　　1. Under normal circumstances, UPS equipment must be inspected every four years. First, all fans of the UPS must be replaced. Then, based on the operating conditions, professionals can check the ripple condition of the DC circuit and check the appearance of the DC capacitors and AC capacitors. If there is no abnormality, use a special meter to test the capacitor capacity to determine whether to replace the capacitor.

　　2. The cleaning method is to start reinstalling the plug-in after the cleaning and maintenance are completed. Pay attention to the plug-in being inserted tightly and the secondary plug being plugged in properly. Check whether there is resonance between the fan and the cover after powering on.

　　3. If the above conditions are normal, the UPS will continue to manually bypass the power supply load. When there is no load, professional technicians will separately supply power to the UPS and debug the automatic bypass, rectifier and inverter.

　　4. If the debugging is normal, the UPS starts switching from manual bypass to automatic bypass and then to the inverter for power supply.

　　5. Secondly, during dust removal, check whether the connectors and plug-ins are loose or not in firm contact.

　　2. Correct storage method of lithium ion battery 18650 price

　　1. When storing, please pay attention to the temperature not exceeding the range of -20℃~+40℃

　　2. When storing the battery, the battery must be stored in a fully charged state. Since part of the capacity will be lost due to self-discharge during transportation or during storage, please replenish the battery when using it.

　　3. When storing for a long time, in order to make up for the self-discharge during storage, please perform supplementary charging. Storing at temperatures above 40°C will have a negative impact on battery life, please avoid this!

　　4. Please store in a dry, low-temperature, well-ventilated place.

　　5. If the battery packaging is accidentally wetted by water during storage or transfer, the packaging carton should be removed immediately to prevent the wet carton from becoming a conductor and causing the battery to discharge or burn out the positive terminal.
