SECTION 5: Fire Fighting Measures How to Extinguish Use fire extinguisher (for Lithium Battery) or Sand. Keep away the batteries from heat sources to avoid a fire. Please do not expose the battery to very high temperature to prevent an explosion and the generation of harmful gas. SECTION 6: Accidental Release Measures N/A Not Applicable) SECTION 7: Handling and Storage Handling Do not charge by higher current or higher voltage than specified. Do not heat, disassemble nor dispose of in fire. Do not solder directly to the battery. Do not short. Do not reverse placement of (+) and (-). Do not discharge by force. In case of leakage or a strange smell, keep away from fire to prevent ignition of any leaked electrolyte. In case of disposal, insulate between (+) and (-) of battery by an insulating material. If leaked liquid gets in the eyes, wash them with clean water and consult a physician immediatey. Do not use new and used batteries together. Do not use different types of batteries together. If you connect two or more batteries in series or parallel, please consult us in advance. Do not use nor leave the batteries in direct sunlight nor in high-temperature areas. Do not apply strong pressure to the batteuries nor handle roughly. Avoid contact with water. Storage Keep batteries out of children s reach. Keep batteries away form direct sunlight, high temperature and humidity. Avoid having the batteries touch each other, because short-circuit causes ignition, leakage, or rupture.
