The 18650 battery is a standard for battery production. It refers to a cylindrical battery with a diameter of 18m and a length of 65m.

The 18650 battery is a standard for battery production. It refers to a cylindrical battery with a diameter of 18m and a length of 65m. The internal storage material can be lithium polymer or a medium such as nickel metal hydride polymer. The production process of the lithium battery is perfected. Most of the storage medium of the 18650 battery is lithium polymer.

Low price 18650 battery for home user
Advantages of 18650 battery:
1. Wide range of use
18650 battery is widely used in various electronic equipment, such as notebook computers, walkie-talkies, portable DVDs, instruments, audio equipment, aviation models, toys, camcorders, digital cameras, etc.
2. Series connection
Can be combined in series or parallel to form 18650 battery pack.
3. Low internal resistance
The internal resistance of polymer batteries is smaller than that of ordinary liquid batteries. The internal resistance of household polymer batteries can even be less than 35mΩ, which greatly reduces the self-consumption of the battery. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control models, and it has become the most promising product to replace Ni-MH batteries.
4. No memory effect
There is no need to empty the remaining power before charging, which is convenient to use.
5. High voltage
The voltage of 18650 battery is usually 3.6V, 3.8V and 4.2V, which is much higher than the 1.2V voltage of nickel-cadmium and nickel-metal hydride batteries.
6. High safety performance
18650 battery has high safety performance, non-explosive, non-burning; non-toxic, non-polluting; cycle times greater than 500 times; good high temperature resistance, discharge efficiency as high as 100% at 65 degrees. To prevent the battery from short-circuiting, the positive and negative electrodes of the 18650 battery are separated.
Therefore, the possibility of its short circuit has been minimized. A protection board can be added to avoid over-charging and over-discharging the battery, which can also extend battery life.
7. Long life
The 18650 battery has a long service life, and the cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries.
8. Large capacity
The capacity of 18650 battery is usually between 1200mah~3600mah. If the 18650 battery is combined to form an 18650 battery group, the 18650 battery group can easily break through 5000mah.
