18650 battery 3.7v 1800mah

　　What are the maintenance methods for UPS batteries and how to clean the dust?

　　When maintaining UPS batteries, it is necessary to maintain a suitable ambient temperature, charge and discharge regularly, and replace waste/bad batteries in a timely manner; it should be noted that UPS equipment must be inspected every four years. The following is a detailed introduction to the "18650 battery 3.7v 1800mah maintenance methods and dust cleaning" techniques".

　　1. Maintenance method of 18650 battery 3.7v 1800mah

　　1. Maintain a suitable ambient temperature

　　In order to effectively charge the 18650 battery 3.7v 1800mah, the ambient temperature range should be between 5-30 degrees. Generally, the charging efficiency will increase with the increase of temperature. However, when the temperature rises above 45 degrees, the performance of the rechargeable battery materials will degrade at high temperatures. , the battery cycle life will also be greatly shortened.

　　2. Charge and discharge regularly

　　The float voltage and discharge voltage in the UPS power battery have been adjusted to the rated value when leaving the factory, and the discharge current increases with the increase of the load. The load should be reasonably adjusted during use, such as controlling electronics such as microcomputers. The number of devices used. Under normal circumstances, the load should not exceed 60% of the UPS rated load. Within this range, the discharge current of the 18650 battery 3.7v 1800mah will not be over-discharged.

　　3. Replace waste/bad batteries promptly

　　In the continuous operation and use of UPS batteries, due to differences in performance and quality, it is inevitable that the performance of individual batteries will decline, the storage capacity will not meet the requirements, and damage will be inevitable. When certain batteries/batteries in the battery pack are damaged, maintenance personnel should inspect and test each battery to eliminate damaged batteries. When replacing a new UPS power battery, you should strive to purchase batteries of the same manufacturer and model. It is prohibited to mix acid-proof batteries, sealed batteries, and batteries of different specifications.

　　2. Tips for cleaning dust from UPS batteries

　　1. Under normal circumstances, UPS equipment should be inspected every four years. First, all fans of the UPS should be replaced. Then, according to the operating conditions, professionals will 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 cover after power is turned 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.
