3.7v 2200mah 18650 lithium battery

　　What is the function of a 3.7v 2200mah 18650 lithium battery and what are the methods of disassembly?

　　When the 3.7v 2200mah 18650 lithium battery is starting, the battery supplies power to the starter and ignition system. When disassembling the battery, disassemble the negative and positive connectors, remove the locking belt, and follow the opposite steps to install it. The following is a detailed introduction. Function of 3.7v 2200mah 18650 lithium battery and how to disassemble it”.

　　1. The function of 3.7v 2200mah 18650 lithium battery

　　1. When the engine is started, the battery supplies power to the starter and ignition system (gasoline engine).

　　2. When the engine is running at low speed, the battery supplies power to all electrical equipment and the generator excitation winding.

　　3. When the engine is running at medium or high speed, the battery converts the remaining electrical energy of the generator into chemical energy and stores it.

　　4. When the generator is overloaded, the battery assists the generator in supplying power to electrical equipment.

　　5. The battery is also equivalent to a large capacitor, which can absorb the instantaneous high voltage appearing in the circuit, protect electronic components, and also plays a very important role in maintaining voltage stability of the automotive electrical system. This function can only be guaranteed when the battery is in good working condition, which is easily overlooked by people.

　　2. How to disassemble the 3.7v 2200mah 18650 lithium battery

　　1. Loosen the nut of the negative electrode connector: Open the two fixing buttons of the insulation cotton, and you can see the two red and black insulation covers on the positive and negative electrode connectors. Open the insulation cover and you can see the locking nut;

　　2. Disassemble the negative electrode connector: Use a wrench or hex socket to unscrew the fastening nut of the negative electrode, then use a flat-blade screwdriver to slowly pry open the fastening block, and then pull out the negative electrode connector;

　　3. Disassemble the positive connector: Use the same method to disassemble the positive connector;

　　4. Disassemble the locking strap: Unscrew the nut used to fix the battery's locking strap, loosen the locking strap, and then take out the battery.

　　5. When installing a new battery, just follow the reverse steps. However, it should be noted that the order of installing the positive and negative connectors is "positive first, then negative", which is opposite to that of disassembly. The principle is the same, both to prevent the risk of short circuit and ensure safety.
