He had kept the spare battery for the e-cigarette in his trouser pocket, together with coins and a bunch of keys. This caused a short circuit; the battery turned into a flamethrower.<\/p>\n<p>Empa battery expert Marcel Held recreated the situation in the laboratory for the SRF television team: He removes the insulating foil from a standard-size 18650 lithium-ion battery and places the battery in a beaker full of nuts. Behind a protective screen, in a chemical fume hood, Held then fills up the beaker with some 5-centime coins (see also <a href=\"https:\/\/www.youtube.com\/watch?time_continue=5&amp;v=g-d5PJoMzbs\">Video film<\/a> to it). The upper contact of the battery, which was previously exposed, is also contacted. A short circuit occurs, and after just under ten seconds, the battery ends its life in a fireworks display about 30 centimeters high.<\/p>\n<h5><strong>Intended for installation in battery packs only<\/strong><\/h5>\n<p>Standard size 18650 batteries carry the warning \"DANGER - DO NOT USE OUTSIDE OF BATTERY PACK\". Such batteries are only intended for installation in battery packs of laptops, power tools, e-bikes or cars. They should not be used or transported without protective extra wrapping. This is because the insulation of the standard 18650 battery consists only of a thin plastic film. If the insulation at the top end of the battery cylinder is damaged, for example by a bunch of keys, then a single coin is sufficient to short-circuit the positive terminal with the battery housing. Anyone who carries such batteries unpacked in their pants pocket or handbag is therefore literally living in a fire hazard.<\/p>\n<figure id=\"attachment_5908\" aria-describedby=\"caption-attachment-5908\" style=\"width: 680px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-5908 size-medium\" src=\"https:\/\/news.save.ch\/wp-content\/uploads\/2018\/01\/Marcel-Held-Vorbereitung-scaled-1.jpg\" alt=\"\" width=\"680\" height=\"510\" \/><figcaption id=\"caption-attachment-5908\" class=\"wp-caption-text\">The laboratory experiment by Marcel Held. <em>Image: Empa<\/em><\/figcaption><\/figure>","protected":false},"excerpt":{"rendered":"<p>Die SRF-Sendung \u00abKassensturz\u00bb vom 23.
