How to store UPS batteries correctly and maintain them?

　　When storing UPS batteries, pay attention to the temperature not exceeding the range of -20°C to +40°C. During long-term storage, in order to compensate for the self-discharge during storage, recharge must be carried out, a suitable ambient temperature must be maintained, and waste/bad batteries must be replaced in a timely manner. Details are as follows. Introduce "the correct storage method and maintenance of UPS batteries".

　　1. Correct storage method of 3.7v 3000mah 18650 battery

　　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.

　　2. 3.7v 3000mah 18650 battery maintenance methods

　　1. Maintain a suitable ambient temperature

　　In order to effectively charge the 3.7v 3000mah 18650 battery, 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 3.7v 3000mah 18650 battery 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.
