TUTORIAL: All about the e-cigarette / Li-ion battery relationship

Vape is not necessarily easy for everyone, especially when it comes to addressing the issue of batteries (or accumulators), these “batteries” that allow your vaping devices to work. So instead of doing anything, no matter how and ending up with serious injuries, you might as well take the time to learn how to use your sources of energy. For this, we offer here a tutorial on "Li-ion" batteries offered by Pascal Macarty, an expert vapoteur in the field.


A battery, whatever its technology, or even a battery, is a concentrated energy source that needs a conductive element to release its energy.

It is important, if not vital, to watch:

* Never put one or more batteries in your pockets (presence of keys, parts that can short circuit)

* Always store or transport your batteries in boxes keeping them separate from each other

* To carry out the necessary calculations and measurements to check that the assembly carried out is not outside the safety zone of the battery (current too high, short circuit).

* Avoid contact with metal objects, liquids and avoid any shock. Never use a battery that has suffered a shock that has deformed it.

* Always observe the polarity indicated in the MOD or in the user manual.

* To call a specialist for the initiation to the use of a MOD Meca.

* Always lock your Meca or Electro MOD out of use.

* Pay attention to the positive pin of the atomizer when using a MOD hybrid mecan (the positive pin must leave enough - 1 2 mm - 510 connector of the atomizer, and it must be fixed and especially not on spring). Seek advice from a specialist.

* Take care of its batteries: clean the contacts of the battery and the MOD, if black spots of oxidation appear (especially on MOD Meca), to call a specialist!

* Replace the protective plastic sleeve (wrap) if the original one is damaged, and put a label showing which battery model it is, characteristics, etc… -> call a specialist! Do not use the battery if the wrap is damaged or torn.

* To dispose of defective batteries in containers provided for this purpose, not in household garbage cans.

* Do not put an accumulator in the mouth (or any other orifice).

* Do not hold a battery by its poles, but by its protective plastic (the fingers are not always clean, and can cause an oxidation of the contacts of the poles).

* Do not use 18350 rechargeable batteries or other "small" sizes for uses involving strong currents.

* It is often said that placing several batteries in series is dangerous, and indeed it is, but paralleling is just as dangerous without isolation between each battery (see § 4 -> short-circuit by dentritic construction, and § 10 dedicated series and //).

* Do not store a fully charged battery: a battery loaded at 100% and stored for a few months before being used will run down a bit, and most importantly, its life will be impacted.

* Do not leave a Li-Ion battery in a car in the sun, or in checked luggage in an aircraft: risk of fire or explosion very important! (This concerns the ecig, batteries for laptops, tablets, smartphones ... read the warnings of your devices to know if they are equipped with a Li-Ion battery).

* Make sure that the poles of your batteries are clean and without damage: if "black spots" appear on the negative pole, it is the sign of an oxidation by electric flashes, creating an additional resistance in the circuit ( heats the switch on MOD Meca).


The complete battery tutorial Li-ion "To Pascal Macarty is available at this address. You will find many pages there to learn how to use its energy sources safely. This document is intended for all vapers wishing to deepen the subject of batteries. This 22-page document is a compilation of knowledge, accumulated within the community, but also through research and reflection, reading datasheets and blogs, watching videos, tutorials, etc ...

Do not hesitate to share it with those around you, do not forget that the good use of batteries allows you to avoid incidents and therefore to avoid some of the disinformation about the e-cigarette.
