18650 battery lithium ion 2200mah

　　1,12V lithium battery operation process

　　(1) The red terminal is the positive pole (+) of the 12v lithium battery

　　(2) The black terminal is the negative electrode of the lithium battery (-)

　　(3) Before use, turn off the electrical switch and then connect the wiring.

　　(4) Connect the positive step of the household appliance's power to the bright red connector, and connect the negative step to the gray-black connector

　　(5) Switch the power switch after accurate calibration

　　(6) Remove the wiring according to the reverse process of installation after shutdown

　　(7) If you need to ask about the power consumption, please click to display the automatic battery switch.

　　2. 12v lithium battery charging instructions

　　(1) The 12V lithium-ion battery must be discharged before charging.

　　(2) Insert the battery charging hole into the 12V lithium charging interface

　　(3) Insert the charging head power cord plug into the 220V power plug

　　(4) The charging head will glow when the battery is charging

　　(5) After being fully charged with 12V lithium ions, the charging head automatically turns to the signal light to stop battery charging.

　　(6) After the rechargeable battery is fully charged, there is no long-term connection between the charging connector and the rechargeable battery.

　　(7) If the battery voltage is less than 9 volts, charge it as soon as possible

　　3. Precautions

　　(1) It is prohibited to use other charging heads to charge the battery:

　　(2) Reuse of rechargeable batteries when not charging;

　　(3) During application, if the battery casing is abnormal and causes severe heat, please suspend use and check for fault detection after use;

　　(4) It is prohibited to use iron clamps for charging on 12V lithium-ion piles. This method can easily cause the battery to explode:

　　(5) It is prohibited to overload the rechargeable battery, otherwise it may cause explosion:

　　(6) It is prohibited to place rechargeable batteries near hot spots or put them into fire.

　　(7) The current of this rechargeable battery is very large. It is recommended to equip an external over-current protector to maintain the rechargeable battery. It is an air leakage switch 60a-100 highly recommended.

　　(8) It is prohibited to use steel bars to enter the starter car without permission, which may cause the battery to explode. If it is a starter car, a special maintenance line must be added.

　　4. Storage instructions

　　(1) Rechargeable batteries are stored in a dry, ultra-low temperature natural environment. All flammable and explosive objects and organic chemical objects cannot be placed around rechargeable batteries:

　　(2) The rechargeable battery cannot be charged after long-term storage, and the storage working voltage is good: polymer upper and lower: lithium ion battery cells 18650 phosphate battery remains

　　right. Check the rechargeable battery every month. If the working voltage drops, the battery should be charged immediately to a good storage and working voltage category.

　　(3) When it must be placed for a long time, the voltage of the battery must be checked before it can be fully used.
