18650 lithium rechargeable battery

　　How to store 18650 lithium rechargeable battery and how are they different from batteries?

　　The temperature of 18650 lithium rechargeable battery should not exceed -20℃~+40℃ during storage. Once it is handled, it will have a bad impact on the battery life. Please avoid it. It is best to place it in a well-ventilated place. In addition, the difference from batteries includes the main body. , different functions, different characteristics, etc., then the relevant content will be introduced in detail below.

　　1. Correct storage method of UPS 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. The difference between 18650 lithium rechargeable battery and storage batteries

　　1. Different subjects

　　UPS: It is a system device that connects the battery to the host and converts DC power into commercial power through module circuits such as the host inverter.

　　Battery: It is a device that directly converts chemical energy into electrical energy. It is a battery designed to be rechargeable and can be recharged through a reversible chemical reaction.

　　2. Different functions

　　UPS: used to provide stable and uninterrupted power supply to a single computer, computer network system or other power electronic equipment such as solenoid valves, pressure transmitters, etc.

　　Batteries: The capacity and weight of batteries cannot be effectively improved, so they are used in automobile and motorcycle engines.

　　3. Different characteristics

　　UPS: When stabilizing the mains power supply, the input voltage range of UPS is relatively wide, generally from 170V to 250V, and the quality of the output power supply is quite high. The output voltage of a backup UPS is between 5% and 8%. The output frequency is stable at 1Hz.

　　Battery: Use a lead plate filled with sponge lead as the negative electrode, a lead plate filled with lead dioxide as the positive electrode, and 1.28% dilute sulfuric acid as the electrolyte.
