Battery Safety

Posted by Peter Nelson on

Battery safety is of paramount importance when using an e-cigarette or mod. 

Before I begin I want to reassure anyone that is thinking about starting or taking up using an e-cigarette that this does not apply to most of the products on the market. Most starter kits have there batteries enclosed in a sealed unit and regulated and protected by that unit. This blog is aimed at vapers who are looking to move on to more powerful mods with removable batteries.

The batteries in question, typically a 18650 type, pack a powerful punch. The last thing you need is for them to short out and cause what is known as a "thermal runaway"

Thermal runaway occurs when the battery heats up and keep son getting hotter in an uncontrolled manner leading to battery failure, and in the most dramatic cases this results in a small explosion or fire.

Please be aware this is not unique to e-cigarette batteries, there are lots of examples of the same thing happening to mobile phones, laptops etc.

There are steps you cant take to prevent this from happening, most cases of thermal runaway can be pinpointed to battery damage or neglect and this can be rectified if you follow a few simple rules.

First of all never use batteries that have damage to the outer wrap, no tears rips or nicks should be visible at all on the wrap. Under no circumstances use a battery that has this kind of damage. If in doubt err on the side of caution, and since these batteries are expensive there are companies that specialise in re-wrapping them so you don't necessarily have to throw them away.

Secondly you need to be careful with storage. It doesn't matter if they are in a drawer or in a handbag or you pocket. Never store batteries loose! If a metal object, such as your car keys, touched them you are in danger of a short, this can then lead to thermal runaway, and if they are in your pocket can lead to harm. Avoid this by simply storing them in a protective case, such as here, all shops and websites will sell them and they are not expensive.

So there you go two simple rules to follow when using mod batteries to keep you safe. If everyone followed these we would see fewer examples of exploding batteries. So be safe and vape safe!
