The general configuration of the 18650 lithium battery is as follows:
Single section nominal voltage is generally: 3.6V or 3.7V
Charging voltage is generally 4.20V (4.2V-4.3V for lithium cobaltate)
* The small discharge termination voltage is generally 2.75V, below which the battery capacity can be seriously reduced or even scrapped
* Charge termination voltage: 4.20V
Diameter: 18±0.2mm
Height: 65±2.0mm
Capacity: More than 1000mAh, some brands will mark 3600mAh or 4500mAh amazing capacity, the current 18650 battery capacity to do the best is Sanyo, can do 3100mAh, but the price is not low.

18650 lithium battery repair method
1, lithium battery repair method one
Use an eraser or other cleaning tool to remove rust from the surface.
Principle of lithium battery repair Method:
The metal surface of lithium battery used for a long time will have a certain degree of oxidation, resulting in bad contact between mobile phone battery and mobile phone, lithium battery use time is shortened, and the use of erasers or other cleaning tools can erase the surface of the rusty material, so that the battery and mobile phone contact better.
2, lithium battery repair method two
Take off your battery after all use up, use temperature treatment, the battery in the case of unstable temperature will greatly shorten the use of time, because the battery is no electricity and a considerable part of the lithium ion has memory electricity with this method can make the memory electricity release part, winter is coming, put outside for a while, and then get to the house.
The principle of lithium battery repair method two:
Low temperature can cause changes in the electrolyte inside the lithium battery, promoting chemical reactions in the battery that has just been frozen. The use of lithium batteries is a process of charging and discharging. During this time, the negative and positive charges in the cell collide with each other. The reason why batteries become more and more unused is that at normal room temperature, the internal kinetic energy of the electrons is relatively large, so the battery is active and leakage is relatively frequent. When the lithium battery is placed in a low temperature environment, the microstructure of the lithium film and electrolyte on the surface of the lithium battery as well as their interface will change significantly, resulting in temporary inactivity inside the battery and reduced leakage current. So after recharging the phone, the battery life will increase.

There is another way, take off the battery, put it for about a week, the electricity will be slowly consumed, need to use the machine will be completely consumed. And then full charge, estimate your charging time must be very short, after full, disconnect again, repeated several times, absolutely effective.
The principle of lithium battery repair method three:
The life cycle of lithium battery is about 600 times. If the number of charging times is too much, the thermal motion of molecules will gradually destroy the internal molecular arrangement microstructure, and the efficiency of charge storage will gradually decrease. The freezing process is easy to destroy the original internal structure of the battery, which may increase the ability to charge charge in a short time, but long-term use may not be effective. Once the microscopic structure in lithium batteries is destroyed, it is impossible to recover completely, and long-term use of this method will accelerate the loss of mobile phone batteries.
Lithium-ion battery repair method three principle: Deep discharge of the phone, is to deplete the internal power, to achieve a deeper degree of recharging, which requires some unconventional methods. Find a way to connect the phone to a small 1.5V light bulb, and the battery's internal charge will be transferred to the bulb until it's all out. The phone needs to slowly use up power through lower voltages. Normally, when the phone is connected, it will automatically shut down if it is below the rated voltage of 3.6 volts. The phone's battery lasts longer when it is recharged after it has been drained.

18650 lithium battery use
The number 18650 represents the external size: 18 refers to the battery diameter of 18.0mm, 650 refers to the battery height of 65.0mm. Common 18650 batteries are divided into lithium ion batteries, lithium iron phosphate and nickel metal hydride batteries. Voltage and capacity specifications: nickel-metal hydride battery voltage: 1.2V 2500MAH common capacity: 3.6V Li-ion battery voltage: 1500MAH-3100MAH Common capacity:
The 18650 battery life is theoretical for 1000 cycles of charge. Due to the large capacity per unit density, it is often used in most notebook batteries. In addition, 18650 is widely used in various electronic fields because of its stable performance in work: It is often used in high-grade bright light flashlight, portable power supply, wireless data transmission, electric heating warm clothes, shoes, portable instruments, portable lighting equipment, portable printers, industrial instruments, medical instruments and so on.
Generally, 18650 batteries are used more in industry and less in civil use. It is common to use more batteries in notebooks and high-grade flashlights.
