3.7v 3000mah 18650 battery

　　How to install 3.7v 3000mah 18650 battery and how to clean the dust?

　　Before installing the 3.7v 3000mah 18650 battery, check whether the battery is damaged. If there is no problem, connect the 3.7v 3000mah 18650 battery to the mains and charge the battery. In addition, if you need to clean the dust from the battery, you need DC capacitors and AC capacitors. Next, I will introduce the details to you.

　　1. Installation of 3.7v 3000mah 18650 battery

　　1. Packaging inspection

　　Open the packaging box, and inside it should be: USP battery and instructions. Remove the USP battery and check if it was damaged in transportation. If there is any damage or parts missing, do not turn on the machine and notify the carrier or dealer. Connect the battery. Connect the red wire of the battery connection on the back panel of the USP battery to the positive terminal of the battery, and the black wire of the battery connection to the negative terminal of the battery.

　　2. Mains power connection

　　When the input power cord connects the usp battery to the mains, start charging the battery. It is recommended to charge for 6 hours before use. To connect the device, use the device's input power cord to connect to the regulated battery output socket on the back panel of the USP battery.

　　3. Turn on usp battery

　　When turning on the usp battery, lightly press the switch button and the indicator light will light up. The usp battery has a DC start-up function, which can directly start the UPS without the need for mains power, which is convenient to use. Once the mains power is interrupted and the UPS switches to backup power supply, please promptly save other loads on the personal computer or perform other power outage emergency measures. After the mains power is restored, please turn on the usp in time to charge the battery. Turn off usp battery.

　　2. 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 inspection, cleaning and maintenance are completed. Pay attention to the plug-in being inserted tightly and the secondary plug being inserted 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.
