18650 rechargeable battery lithium 3.7v 3500mah

　　How to install and store UPS batteries?

　　1. Installation of 18650 rechargeable battery lithium 3.7v 3500mah

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

　　2. Before the 18650 rechargeable battery lithium 3.7v 3500mah is put on the shelf, physical inspection must be carried out and the open circuit voltage must be measured to avoid rework. When one end of the cable is connected to the 18650 rechargeable battery lithium 3.7v 3500mah, the other end should be insulated or held in the palm of your hand to prevent misplacement and sparking.

　　3. After one end of the wiring is connected, the other end should tap the pole 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 18650 rechargeable battery lithium 3.7v 3500mah 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 PS battery pack is connected in series, the voltage between the total positive and total negative of the 18650 rechargeable battery lithium 3.7v 3500mah 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 18650 rechargeable battery lithium 3.7v 3500mah 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. How to store UPS batteries

　　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. Storage at temperatures above 40°C will have a negative impact on battery life, so please avoid it.

　　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.
