How to choose several models of steam electronic smoke battery 18650 18500 18350 and 26650?

Most of the batteries used in e-cigarettes are external lithium batteries, and some e-cigarette hosts are built-in lithium batteries or aircraft model batteries. There are four types of external lithium batteries: 18650 18500 18350 and 26650.

1.Type 18650

The ancestor of the lithium-ion battery (a standard lithium-ion battery model set by Sony Company in Japan to save costs)Numeral 18 denotes a diameter of 18 mm, 65 denotes a length of 65 mm, and 0 denotes a cylindrical battery. The capacity is generally between 1200mAh and 3600mAh. Most electronic smoke devices use this battery, such as mechanical rod, pressure regulating rod, and pressure regulating box;


2.Type 18500

In the figure, 18 denotes a diameter of 18mm and a length of 50mm, and 0 denotes a cylindrical battery. The capacity of this battery is smaller than that of 18650, and it is less used. Only a few mechanical rods are used;

3.Type 18350

Numeral 18 denotes a diameter of 18 mm, a length of 35 mm, and 0 denotes a cylindrical battery. The battery capacity is the smallest, but its volume is the smallest, which can reduce the size of the equipment, so there are a few mechanical rods or pressure regulating rods;

4.Type 26650

Numeral 26 denotes a diameter of 26 mm, a length of 65 mm, and 0 denotes a cylindrical battery. This battery has the characteristics of large capacity, and a few voltage regulating boxes can be used;

Attachment: advantages of lithium battery

1. Large capacity: the capacity of a 18650 lithium battery is generally between 1200mAh and 3600mAh, while the general battery capacity is only about 800MAH;

2. Long service life, 18650 lithium battery has a long service life, and the cycle life can reach more than 500 times in normal use, more than twice that of ordinary batteries;

3. High safety performance, 18650 lithium battery has high safety performance, no explosion, and no combustion; Non-toxic, pollution-free, ROHS trademark certification; All kinds of safety performance are completed in one go, and the cycle times are more than 500 times; The high-temperature resistance is good, and the discharge efficiency reaches auto at 65 ℃. To prevent battery short circuits, the positive and negative electrodes of the 18650 lithium battery are separated. So the possibility of a short circuit has been reduced to the extreme. A protective plate can be installed to avoid overcharging and discharging of the battery, which can also prolong the service life of the battery;

4. The voltage is high. The voltage of the 18650 lithium battery is generally 3.6V, 3.8V, and 4.2V, which is much higher than the voltage of 1.2V of nickel-cadmium and nickel-hydrogen batteries;

5. No memory effect, no need to empty the remaining power before charging, easy to use;

6. The internal resistance of the polymer cell is small. The internal resistance of the polymer cell is smaller than that of the general liquid cell. The internal resistance of the domestic polymer cell can even be less than 35m Ω, which greatly reduces the self-consumption of the battery and extends the standby time of the mobile phone. It can completely reach the level of international standards. This polymer lithium battery supporting a large discharge current is an ideal choice for remote control model and becomes the most promising product to replace nickel-hydrogen battery;

7. 18650 lithium battery pack can be assembled in series or parallel;

8. Wide range of use: notebook computers, walkie-talkies, portable DVDs, instruments and meters, audio equipment, model aircraft, toys, video cameras, digital cameras, and other electronic equipment can be used.
