FYI Battery safety: Getting the basics right for you and your customers BY BENEDICT ‘NED’ JONES A large portion of mods on the market these days call for removable cells rather than built-in cells, which can only be charged through the mod. An inappropriately used cell can spell disaster for a device and its user, so it’s important that you only provide quality choices for your customers. Large manufacturers such as Sony, Samsung, LG, and Panasonic and Sanyo are known to accurately mark the capabilities of their cells. It’s generally safe to assume that the continuous discharge rating (CDR) and capacity (mAh) ratings will be correct with legitimate cells from these manufacturers. The CDR of a cell tells us the current we can draw from it continuously without causing permanent damage or quickly degrading its life span. While it is true that in many cases vapers can push cells past their CDR to achieve higher power outputs, this is not recommended and certainly shouldn’t be attempted by those new to vaping. Exceeding the CDR of a given cell will cause it to degrade much more quickly than in normal use, meaning such a user will have to be disciplined about replacing their cells frequently in order to avoid a dangerous incident such as thermal runaway – an explosion caused by a cell overheating. Vapers looking for high power output should use cells with a high CDR, such as the LG HB6, Sony VTC4 or Samsung 30T which are rated at 30A, 30A and
