Batteries in e-cigarettes

Of course, like many other electronic devices, e-cigarettes also use batteries to power the evaporator. The battery is one of three main modules that are installed in most electronic cigarettes: evaporator (also called vaporiser), liquid tank and battery. The performance and quality of a rechargeable battery determines how good the vapour development in the e-cigarette is and how long it can be used before it has to be recharged. Therefore, it is always advisable to use a battery from a known manufacturer.

Options for activating batteries

In most models of electronic cigarettes, the battery is activated in one of two ways. A method is that the user simply sucks on the mouthpiece and the resulting suction via a vacuum switch the battery and evaporator activated (FairSmoke battery). The other method, the battery is activated in the old-fashioned way via a switch. As soon as the user presses the button, the evaporator and battery are activated and the device starts to evaporate liquid in the tank.

Battery units and battery carriers

For e-cigarettes there are two types of construction: battery unit and battery carrier. With the battery units, the battery is firmly connected to the evaporator and the other components of the e-cigarette. As a result, the individual components of the device can not be replaced, and if, for example, the evaporator is worn or the battery has a faulty fault, the entire device must be replaced. Thus, this design is usually used only in disposable models that are quite cheap to buy and only for temporary operation. The battery units also have other disadvantages: the user has no control over the wattage or the temperature development in the evaporator. The advantage of rechargeable battery units is that the devices are very user-friendly and the user does not have to worry about the compatibility of rechargeable battery and e-cigarette.

In the case of the battery carriers, however, all components of the e-cigarette can be replaced. For example, the user can decide for themselves which type of rechargeable battery or evaporator they want to use in their device. In addition, the battery carriers (also known by the English term Mods) offer many more advantages. For example, the user may control many parameters of the electronic cigarette. By controlling the wattage, for example, the electrical resistance of different evaporators can be compensated. This is expressed in ohms (Ω) and is different for each evaporator. The higher the resistance, the more wattage the battery should deliver to the evaporator. By controlling the temperature development in the evaporator, the user can also perfectly control the vapor evolution depending on the liquid used. Since each mixture of PG and VG at a different temperature reaches the optimum vapor development, the battery carriers are therefore by far the most popular variant with experienced steamers.

Battery types for electronic cigarettes

There are generally two different types of rechargeable batteries for e-cigarettes. On the one hand, there are models in which the batteries can be replaced and look like large batteries, which are known from flashlights or other electrical devices. Of course, these have the advantage that the battery can be easily replaced when worn. In addition, the user can decide for himself, from which manufacturer the battery comes. For example, such a battery from Samsung or Sony can be used for a device from another manufacturer. However, it is very important that the user always uses the right battery for their own device. Otherwise, it can lead to dangerous malfunctions.

In the other variant of the battery is connected directly to the evaporator of the e-cigarette. As a result, the battery can not be replaced, and in case of wear or other defects, the entire device must be replaced. On the other hand, there is no danger that a wrong battery will be used in the device. This method is mainly used in entry-level models, in the so-called "mods" are always used interchangeable batteries.

Another distinction between the different battery types is whether the battery is clocked, clocked or regulated. With clocked batteries, the exact same output is always produced, regardless of the duration of use and residual charge. This type of battery is most commonly found in electronic cigarettes. In the case of uncalculated batteries, on the other hand, higher power is produced at the beginning, which then becomes weaker and weaker until the battery is completely discharged. This type of battery is rarely found in e-cigarettes. Finally, there are still regulated batteries in which the power can be adjusted manually. Thus, the steam evolution for different evaporator heads (so-called "coils") can be regulated. Higher resistance coils (expressed in Ω) require higher battery power to produce the same amount of vapor. This type of battery is mainly used in more sophisticated models such as the mods and preferred by many fans of e-cigarettes, because it gives them much more freedom to produce the optimal steam development.

While there are many different types of batteries, almost all of them today are lithium-ion batteries. This type of battery is used today in almost all electrical devices, from cell phones to laptops to electric cars. It provides several advantages over older technologies. Not only can lithium-ion batteries store significantly more energy, they are also lighter, but also have much longer lifetimes and, moreover, do not need to be completely emptied each time to deliver optimal long-term performance. For older technologies such as NiCa or NiMH batteries, the user had to completely empty and then fully charge them with each charging cycle in order to avoid faster wear. Another advantage of lithium-ion batteries is that they can be used directly after receiving the product and do not have to be fully charged. Although some manufacturers still recommend this, there is basically no reason for it, because it makes no difference to the technology.

When unloading, however, users should pay attention to lithium-ion batteries that they never completely empty them. Namely, as soon as the voltage drops below about 2.5 volts, problems with the detection by the device can occur and the life of the battery can be extremely shortened. Thus, such a case can already cause a reduction of the service life of up to 20%. To avoid this, it is advisable to fully charge the lithium-ion batteries every day as possible. The maximum charge for these batteries is usually 4.2 volts, at the level of 2.8 volts they should be recharged at the latest. When used regularly, most e-cigarettes should have an average lifespan of two to four hours.

Even if the battery is not used for a long time, it should be recharged before using it for the first time, as it will automatically deflate over time. Furthermore, it is recommended for longer storage times that the battery is not previously charged to 100%. This can affect the life of the battery, because a higher voltage accelerates the aging process. In addition to these tips, batteries should of course always be stored in cool and dry places and also not together, but always separated from each other.
