The investigation found that 80% of the accidents were related to electronic cigarette battery failure, especially when the battery was charging.

According to a report issued by the US Fire Service, most fires and explosions caused by e-cigarettes are related to e-cigarette batteries.

Therefore, when using e-cigarettes, it is necessary to first understand the knowledge of e-cigarette batteries!

1. What is a power battery?

Power lithium batteries can be discharged at a higher rate.

Taking lithium iron phosphate power lithium battery and ordinary lithium battery as examples, although the entire positive and negative electrode material system and structure are the same, the positive and negative electrode material particles of the dynamic lithium battery are smaller than the ordinary type. (Add a lot of impurities and speed up the chemical reaction), the use of auxiliary materials and oxides has better conductivity, and the kinetics of the lugs produced by the normal phase and the reverse phase are also larger than the ordinary type (internal resistance replacement) . Higher frequency and satisfaction).

2. What are 18350, 18650 and 26650?

These 18380s refer to cylindrical batteries with a diameter of 18MM and a length of 65MM. 26650 is a cylindrical battery with a diameter of 26MM and a height of 65MM. These are the models of power batteries. The first two numbers indicate the diameter of the battery, and the last three numbers indicate the height of the battery.

3. I use 18350 battery. What is the appropriate range of resistance?

Generally, the higher 18350 in the market is 15A, so please try to make it higher than 0.8.

4. How to measure resistance with a multimeter?

Adjust the multimeter in your hand to 200K.

b. Calculate resistance error by short-circuiting positive and negative watch hands.

C. Touch the positive and negative pins of the atomizer. After reading, initialize the previously calculated error to obtain the current resistance value of the hot wire.

5. Can batteries be connected in series? Is it dangerous?

Serial connection is dangerous, please don’t do it.

6. What is a damping tester? Do I have to use a damping tester to make e-cigarettes?

The damping tester is a small box, and the resistance value can be read after the atomizer is installed. Also called resistance box. If you are a poleman, you do not need to purchase this equipment. If you are a mechanical drawbar machine, please measure the resistance accurately and accurately before turning on the atomizer.

7. Battery life issues? How long can it be used normally?

Normally, the output power is about 15W, which can last for 24 hours without problems. Two spare batteries are always a good choice. Whether the battery can be used for a long time has a lot to do with the frequency and power of the electronic cigarette.
