Use special caution when working with Li-ion (Lithium-ion), LiPo (Lithium-ion Polymer) and any rechargeable cells, as they are very sensitive to charging characteristics and may explode or burn if mishandled. Make sure the user has enough knowledge of Li-Ion (Lithium-ion), LiPo (Lithium-ion Polymer) and any rechargeable cells in charging, discharging, assembly and storage before use. Always charge in/on a fire-proof surface. Never leave charging batteries unattended. Do not use any rechargeable battery as well as any battery charger if any visible damage is present, as well as if the cell or charger has been stressed through mishandling, accidental or otherwise, even if damage may not be visible. Always store and transport rechargeable cells in a safe, non-conductive container in a controlled environment. Dispose of all battery cells and chargers in accordance to local laws and mandates.
