There is wide media reporting questioning the safety of electronic cigarette batteries and while you may have seen some stories in the media about exploding e-cigarette batteries, good quality batteries from reputable suppliers combined with the sensible handling of batteries and correct precautions will lead to safe vaping.
If treated incorrectly, lithium batteries can become very hot, vent off gas, and react with a process that is called ‘thermal runaway’. It’s important to note that reputable manufacturers add three layers of protection to Li-ion batteries to ensure that this doesn’t happen.
For those interested in more detail…
Thermal runaway occurs when the separator sheet that keeps the positive and negative electrodes apart gets broken as a result of the battery being dropped or damaged. When the electrodes touch, the battery heats up very quickly causing the electrolyte solution within it to vent. The heat itself or a nearby spark can then ignite the venting fluid resulting in a fire. This process is avoided by limiting the amount of active material, including safety mechanisms in the battery cell itself, and adding an electronic protection in the battery pack. There, we saved you from having to Google it.
It is important to always buy from a reputable supplier like Liberty Flights who have taken the above precautions. At Liberty Flights we can verify all our batteries come with the following documentation:
CE Certificate of Conformity, including the detailed test report. Restriction of the use of Certain Hazardous Substances (RoHS) Waste Electrical and Electronic Equipment (WEEE) certificate, under Directive (2011/65/EU) and the supporting test report. Other reports (e.g. IEC62133, UN38:3), transportation reports and Safety Data Sheets (SDS) are also required and checked.
We always recommend storing and transporting loose batteries separated from one another, in non-conductive (e.g. plastic) containers. Never store batteries where they can come into contact with metal items such as loose change or keys as these can cause a short circuit.
