Hazard Warnings, Potential Faults

Danger to life and health caused by an electric arc if active live parts are touched;
Danger to life and health (burns, ventricular fibrillation or heart stopping) caused by body currents if active live parts are
touched;
Danger to health caused by organic substances and acids that might be emitted in case of failure conditions;
Danger of explosion and fire when operating with overvoltage, after under-voltage, at too high temperature or with too high
charge or discharge power;
Environmental hazard from released substances, e.g. electrolyte;
Hazard by mechanical impact: the housing can have sharp edges due to manufacturing process, thus special care must be
taken.

A characteristic feature of lithium-ion cell is a high energy content with a low weight. In the event of a fault, the thermal energy
released is a multiple of the electrically usable energy. Unlike normal lead starter batteries, the electrolyte is not aqueous but
organic. The cells are gas-tightened. In other words: No gases or liquids escape during normal operation.

Unlike normal starter batteries, the chemical hazard is not from acids and the generation of hydrogen, but from organic solvents
and the used conducting salt and their secondary chemical reactions when released in the event of a fault. Under faulty conditions,
toxic and corrosive agents might be set free.
