What are the 3.7v 2200mah 18650 lithium battery models and replacement techniques?
The 3.7v 2200mah 18650 lithium battery model is A and W indicating the type of battery, Q is the car starting battery, M is the motorcycle battery, etc. Next, I will introduce to you the 3.7v 2200mah 18650 lithium battery models and what are the replacement techniques?
1. 3.7v 2200mah 18650 lithium battery model
1. 6 means it is composed of 6 single-cell batteries, and the voltage of each single-cell battery is 2V, that is, the rated voltage is 12V.
2. Q represents the purpose of the battery, Q is the car starting battery, M is the motorcycle battery, JC is the ship battery, HK is the aviation battery, D means the electric vehicle battery, and F means the valve-controlled battery.
3. A and W indicate the type of battery, A indicates dry-charge battery, W indicates maintenance-free battery, if not marked, it indicates ordinary battery.
4. 54 means that the rated capacity of the battery is 54Ah (the amount of electricity output by the battery when it is discharged at room temperature at a rate of 20h with a discharge current of 20h).
5. The subscript a indicates the first improvement to the original product, the subscript b after the name indicates the second improvement, and so on.
2. 3.7v 2200mah 18650 lithium battery replacement skills
1. Loosen the nut of the negative electrode connector: Open the two fixing buttons of the insulation cotton. You can see 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. Remove the negative electrode joint: Use a wrench or hex socket to unscrew the fastening nut of the negative electrode respectively, then use a flat-blade screwdriver to slowly pry open the joint block, and then remove the negative electrode joint head.
