18650 is a lithium-ion batteryThe originator - a standard lithium-ion battery model set by the Japanese SONY Corporation to save costs back then, where 18 indicates a diameter of 18mm, 65 indicates a length of 65mm, and 0 indicates a cylindrical battery.
The theoretical lifespan of an 18650 battery is 500 cycles of charging. Due to its large capacity per unit density, 18650 is mostly used in laptop batteries. Because of its excellent stability during operation, it is widely applied in various electronic fields: it is often used in high-end high-intensity flashlights, portable power sources, wireless data transmitters, electric heating warm clothing and shoes, portable instruments and meters, and portable lighting equipment. Portable printers, industrial instruments, medical instruments, etc.
Large capacity: The capacity of 18650 lithium batteries is generally between 1200mah and 3600mah
2. Long service life: Under normal use, the cycle life can reach over 500 times, which is more than twice that of ordinary batteries.
3. High safety performance: High safety performance, non-explosive and non-flammable; Non-toxic and pollution-free, it has passed the RoHS trademark certification, has good high-temperature resistance, and can be equipped with a protection board to prevent overcharging and overdischarging of the battery, thus extending the battery's service life.
4. High voltage: The voltage of 18650 lithium batteries is generally 3.6V, 3.8V and 4.2V, which is much higher than that of nickel-cadmium and nickel-metal-hydride batteries.
5. No memory effect: There is no need to completely drain the remaining power before charging, making it convenient to use.
6. Low internal resistance: It greatly reduces the self-discharge of the battery and extends the standby time of the mobile phone. This polymer lithium battery that supports large discharge currents is an ideal choice for remote control models and has become the most promising product to replace nickel-metal-hydride batteries.
7. They can be connected in series or parallel to form 18650 lithium battery packs
8. Wide range of applications: laptops, walkie-talkies, portable DVD players, instruments and meters, audio equipment, model aircraft, toys, video cameras, digital cameras and other electronic devices
【 Name 】 :18650 rechargeable lithium battery
