WARNING 2.1 Don’t heat or disposed in fire or water .Don’t modify or disassemble the battery. It will be dangerous, and may cause ignition, heating, leakage or explosion. 2.2 Don’t short-circuit positive(+) and negative(-) terminals. Keep away from metal or other conductive materials. Jumbling the batteries of direct contact with positive(+) and negative(-) terminals or other conductive materials may cause short-circuit. 2.3 Don’t reverse the positive (+) and negative (-) terminals. 2.4 If the battery gives off an odor, generates heat, becomes discolored, or in any way appears abnormal during use, recharging or storage, immediately remove it from the device or battery charger and stop using it. 2.5 Don’t solder the battery directly. Excessive heating may cause deformation of the battery components such as the gasket, which may lead to the battery swelling,leakage, explosion,or ignition. 2.6 Don’t use abnormal cell which has damages by shipping stress, drop, short or something else, and which gives off electrolyte odor.
