Indispensable to our vape kits, batteries have a central place in the world of vaping. Today, the batteries are integrated with the pod kits, they often fuel lively discussions on autonomy or safety. Misconceptions about them are numerous and widespread. So we at CAK decided to select a few to help you sort out the real from the fake.
Always fully charge a battery before first use.
FAKE. There was a time when batteries, especially those made of Nickel Cadmium, had to be “calibrated”, which involved a first full charge after unpacking. The arrival of Lithium-Ion batteries, which have since become widely accepted, has changed the situation. They incorporate a “self-calibration” system which makes this step unnecessary. In practice, it does no harm to fully fill your battery or battery before using it, but there is also no problem if you don’t.
It is best to drain a battery completely before recharging it.
FAKE. This urban legend also dates back to when nickel batteries were the norm. They indeed have a “charging memory” which requires complete recharging. Again, with Lithium-Ion, this is not the case. It’s quite the opposite! If you get into the habit of completely emptying a battery before recharging it, you risk eventually reducing its capacity. It is therefore preferable not to wait until it is dry to refuel.
The more you charge a battery, the more it wears out.
True and false. You should know that a battery has a limited lifespan. We then speak of charge cycles (generally between 300 and 1000). The more they are started, the less your batteries will perform. On the other hand, it must be understood that we are talking here about complete 100% recharge-discharge cycles and not simple daily recharges. Recharging a battery from 75 to 100% 4 times is, therefore, the same as a full charge. It is even preferable if we take into account what we have seen in the previous paragraph.
You can leave your battery charging overnight.
True and false. Lithium-Ion batteries are equipped with a system that stops charging when it reaches 100%. There is therefore no risk of overload. On the other hand, if you do not disconnect your battery from the power source, it will then drain slightly, and charging will resume. This can therefore reduce its lifespan because it will start charging cycles unnecessarily. Not to mention the economic and ecological consequences of such a practice.
A battery can explode at any time and for no specific reason.
FAKE. Some television news subjects could make us think that we have uncontrollable little bombs in our equipment. Yet the phenomenon behind these (very rare) explosions is well known. This is called “thermal runaway”, a chain reaction that can be caused by high heat, shock, or a short circuit. Generally, about the batteries, it is a short circuit that is at the origin of the degassing. To protect yourself against this, there are very simple solutions that Pascal also details in an article published on this blog.
