　　How to connect rechargeable battery 18650 3.7v and how to store it?

　　When connecting UPS batteries, the connection scheme must be designed in advance, and physical inspection must be carried out before being put on the shelf. During storage, pay attention to the temperature not exceeding the range of -20°C to +40°C. The battery must be stored in a fully charged state, as detailed below. Let’s take a look at “How to connect and store UPS batteries”.

　　1. How to connect rechargeable battery 18650 3.7v

　　1. Design the connection plan in advance. It is recommended to remove the metal accessories on hand during installation.

　　2. Before putting the rechargeable battery 18650 3.7v on the shelf, it must be physically inspected and the open circuit voltage measured to avoid rework. When one end of the connecting cable is connected to the rechargeable battery 18650 3.7v, the other end should be insulated and protected or held in the palm of your hand to prevent misplacement and sparking.

　　3. After one end of the cable is connected, the other end should tap the pole that needs to be connected when connecting to effectively avoid the impact of incorrect connections.

　　4. When two people are connected at the same time, there should be no connection or potential relationship between the corresponding rechargeable battery 18650 3.7v packs. Because the two people have the same potential, if there is a potential difference between the batteries connected to each other, the battery and the two people will form a circuit, and an electric shock accident may occur.

　　5. After the rechargeable battery 18650 3.7v pack is connected in series, the voltage between the total positive and total negative of the rechargeable battery 18650 3.7v pack is relatively high. When connecting to the MCCB (battery switch), each wire should be connected to the MCCB first and then to the corresponding battery terminal. ; Or leave a breakpoint in the battery pack, and then connect the breakpoint after completing the connection between MCCB and rechargeable battery 18650 3.7v pack. For multiple groups of battery packs connected in parallel, each group should have a broken end, and after connecting the MCCB terminal, use a multimeter to check the polarity and then connect the broken ends.

　　2. Correct storage method of rechargeable battery 18650 3.7v

　　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.
