Li-Ion batteries are the most widely manufactured batteries in the world. If you don't think it is that common you surely wont believe that 40% of the worlds batteries are Lithium Ion. They are used in Laptop, Power tools, robots, electric vehicles, solar grids and almost all devices that requires to store energy.
The International Air Transport Association (IATA) issues regulations on the transport of Dangerous Goods by air, the DGR. The current edition — number 58 — has introduced stricter restrictions on transport and packaging of Lithium-Ion batteries after an increasing amount of incidents. It is imperative to develop and use packaging that is compliant with IATA Dangerous Goods Regulations (DGR) and to follow all other aspects of the regulations.
The KC (Korea Certification) certification mark signifies compliance with Korea’s product safety requirements for electrical and electronic equipment and components that utilise power from AC 50-1000V.
Li-ion batteries contain a protection circuit that shields the battery against abuse. This important safeguard also turns the battery off and makes it unusable if over-discharged. Slipping into sleep mode can happen when storing a Li-ion pack in a discharged state for any length of time as self-discharge would gradually deplete the remaining charge. Depending on the manufacturer, the protection circuit of a Li-ion cuts off between 2.2 and 2.9V/cell.
