Lithium ion rechargeable battery

SECTION 2: Hazards identification

Lithium ion batteries are gas-tight sealed and innocuous, as long as the manufacturer’s Instructions are followed during use and handling. Warning! Never use chargers not intended for the battery type. Do not short circuit. Do not damage mechanically (perforate, deform, take apart, etc.). Do not heat up above the permissible temperature or burn. Keep batteries away from small children. Always store batteries in a cool and dry place. Battery packs are safe to use if handled properly under the parameters given in the instructions for use. Incorrect handling or circumstances that lead to an improper operation can lead to leaks and the escape of the battery contents and decomposition products and to strong associated reactions that endanger the health and the environment. In principle, contact with leaked-out battery components is a health and environmental hazard. Therefore, sufficient body and respiratory protection is necessary when there is contact with conspicuous batteries (leaked- out contents, deformations, discolorations, dents and the like). Battery packs can react very violently when combined with fire, for example, and highly potentially hazardous components can be emitted. Handling and operational safety: Battery packs must be handled according to the instructions for use under all circumstances. This applies especially to compliance with the limits of mechanical and thermal stresses. Battery packs may never be modified or manipulated, as this can cause significant safety risks. Danger! As with other batteries, lithium batteries that have supposedly been discharged can still pose a hazard because they are capable of delivering a very high short-circuit current. A discharge that is too low leads to long-term damage. Deeply discharged battery packs may no longer be charged or operated. Excessively high charging voltages and overcharge must be avoided at all costs. They cannot only lead directly to critical situations, but also have a negative effect on the battery’s life.
