Vape batteries, basic knowledge you must know.
Most vape batteries are 18650, which is almost the standard for box mods. So what parameters do you need to pay attention to to know if the battery is right for you, how to choose, read our article right away.
Why do vapes use 18650 batteries?
18650 rechargeable batteries are widely produced because they are used as raw materials for many products: raw materials for laptop battery production (when you open the battery bar of a laptop, there are many small 18650 batteries) or as in backup chargers (just 2 18650 batteries with charging and discharging circuits make a 5200 mAh backup charger). Even rechargeable lights have 18650 batteries.
It is called 18650 because it has a base diameter of 18mm and a height of 65mm.
Vape inherits this convenience because: compared to other types of batteries, 18650 has advantages, large capacity, large discharge rate, and suitable size -> it becomes the standard battery of vape batteries (for boxes with external batteries).
18650 vape batteries currently have 2 popular lines using different technologies, Li-ion (Lithium-ion) and Li-po (lithium-polymer)
Basically, these two types operate based on the mechanism of exchanging lithium-ion molecules between two poles, differing only in the type of electrolyte and the arrangement of the cells. Li-ion batteries use solvent electrolyte, while Li-po uses polymer membrane.
Because of these technical characteristics, Li-ion has high efficiency but must be wrapped in a thick metal shell, during use, the battery shell is dented, torn and punctured, which can be dangerous. As for Lipo, because it has a safer polymer membrane, diverse shapes but reduces the parameters of V and A usage.
What parameters should you care about in a vape battery:
Depending on which vape device you use, you will choose based on 3 main parameters
mAh: common types are 2100, 2600, 3000. The higher this parameter, the longer the usage time.
A: This parameter represents the output current of the battery. The most common is 20-25A. The higher this number, the stronger and more shocky the current is.
V: This parameter shows the difference in voltage between the two ends of the battery when the battery is empty. For example: the battery case says 3.7V, which means that when the battery is empty, the voltage difference between the two ends is 3.7 Voltz. Normally, fully charged batteries will have a V of 4.2.
If you use a mech device, you will need a large A (discharge) for the device to overcome the delay (loss on the power line to the burner, making the coil heat up slower). However, you need to pay attention to safety issues because when A is large and the ohm resistance is too low, you imagine the current will flow back to the battery, causing danger.
If you use a box mod with an electronic circuit , it is best to use a battery with a large capacity, that is, a large mAh, to increase the usage time.
During the process of using the battery, if you suspect it is no longer good, in addition to monitoring its working capacity, you can use it up and then plug it into an external charger with a measuring screen. If the battery V when exhausted is not at 3.7 but drops to 3.5 or lower, then you should throw away that battery.
Always check the battery casing, especially the black (or white) ring at the positive terminal of the battery. Regularly check the battery body for any dents or torn metal parts, you should not risk your health.
