Warning in handling lithium-ion cells !To prevent the possibility of the cell from leaking, heating, explosion, please observe the following precautions: When charging, use a cell charger specifically for that purpose. Don’t reverse the positive and negative terminals. Don’t immerse the cell in water. Don’t use and leave the cell near a heat source such as fire or heater. Don’t discard the cell in fire or heater. Don’t connect the cell to an electrical outlet directly. Don’t connect the positive and negative terminal directly with metal objects. Don’t transport and store the cell together with metal objects such as necklaces, hairpins, etc. Don’t directly solder the cell. Don’t pierce the cell with a nail or other sharp object.
