Many electronic cigarette players do not know how to choose the battery, the most seen model on the market is 18650 battery, but as long as the 18650 battery is applicable to each device? This article will explain how the mechanical rod selects the battery.
What is an 18650 battery?
The 18650 battery is the originator of lithium-ion batteries, and it is a standard lithium-ion battery model set by SONY of Japan in order to save costs. The number 18 indicates a diameter of 18mm, 65 indicates a length of 65mm, and 0 indicates a cylindrical battery. The capacity is generally between 1200mah and 3600mah.
There are three types of 18650 batteries commonly used, IMR batteries, ICR batteries with protection circuits, and hybrid batteries. High quality IMR batteries are the best choice.
IMR batteries, also known as lithium manganate (LI MN) batteries, are the safest batteries available for e-cigarettes, because the use of safe chemical raw materials, IMR batteries do not need to protect the circuit, and IMR batteries can withstand greater pressure and impact.
How to choose battery for e-cigarette?
1. Reject unprotected ICR batteries! When the ICR battery protection circuit fails, the ICR battery will have a violent chemical reaction in the leakage, resulting in fire or even explosion.
2. Use the right battery! Simply put, if you need to use an atomizer below 1 ohms, then you must use a battery with a discharge current greater than 10 amps.
3. Refuse unbranded batteries! This one will not say, just ask, no brand battery you dare to use? Discharge capacity and battery capacity are two important parameters to consider when choosing a battery. What is the relationship between these two parameters? When choosing a battery, is it for life or performance? For the choice of batteries, the clown personally prefers SONY C5A, C6, which is cost-effective and the kind of regulator mechanical rod is not wrong. (This is not a commercial)
4. Use a good charger! In short, it is recommended to buy the most expensive charger you can afford. The data shows that the vast majority of battery accidents occur while charging. Lithium batteries are not afraid of use and charging, but they are afraid of overcharge and overdischarge.
Overshoot refers to overcharging, including charging current higher than the battery’s carrying range and charging time longer than the battery’s full time. This is called overcharging. And “overdischarge” refers to excessive discharge. It also includes two aspects, one is that the discharge current exceeds the carrying range of the battery, that is, “overload”, and the other is that the battery continues to discharge when the battery is already out of power, eventually causing the battery to be scrapped.
What happens if the battery is not selected properly?
If a bad battery is used, when the maximum continuous output current of the battery is too low and the output current exceeds the standard during use, the pressure of the battery is too high, and the pressure of the battery is increased, resulting in heat of the battery, which will damage the steel shell of the battery, especially the reaction between the internal materials and substances in the air will produce a large amount of gas. When the gas is enough and the pressure is large enough, the tube wall of the mechanical rod will explode, so the battery selection must be careful.
