Document No. Ver Date Page ZJQM-RD-SPC-A0176 0.0 2014/10/15 7/8 Matters needing attention Strictly observes the following needing attention. EEMB will not be responsible for any accident occurred by handling outside of the precautions in this specification. ! Danger z Strictly prohibits heat or throw cell into fire. z Strictly prohibits throw and wet cell in liquid such as watergasoline or drink etc. z Strictly prohibits use leave cell close to fire or inside of a car where temperature may be above 60. Also do not charge / discharge in such conditions. Strictly prohibits put batteries in your pockets or a bag together with metal objects such as necklaces. Hairpins, coins, or screws. Do not store or transportation batteries with such objects. Strictly prohibits short circuit the (+) and (-) terminals with other metals. Do not place Cell in a device with the (+) and (-) in the wrong way around. Strictly prohibits pierce Cell with a sharp object such as a needle. Strictly prohibits disassemble or modify the cell. Strictly prohibits welding a cell directly. Do not use a Cell with serious scar or deformation. Thoroughly read the user's manual before use, inaccurate handling of lithium ion rechargeable cell may cause leakage, heat, smoke, an explosion, or fire, capacity decreasing. z z z z z z z z ! Warning z z z z z z z Strictly prohibits put cell into a microware oven, dryer, or high-pressure container. Strictly prohibits use cell with dry cells and other primary batteries, or new and old battery or batteries of a different package, type, or brand. Stop charging the Cell if charging is not completed within the specified time. Stop using the Cell if abnormal heat, odor, discoloration, deformation or abnormal condition is detected during use, charge, or storage. Keep away from fire immediately when leakage or foul odor is detected. If liquid leaks onto your skin or clothes, wash well with fresh water immediately. If liquid leaking from the Cell gets into your eyes, do not rub your eyes. Wash them well with clean edible oil and go to see a doctor immediately. ! Caution z z z z z z Before using the Cell, be sure to read the user's manual and cautions on handling thoroughly. Charging with specific charger according to product specification. Charge with CC/CV method. Strictly prohibits revered charging. Connect cell reverse will not charge the cell. At the same time, it will reduce the charge-discharge characteristics and safety characteristics, this will lead to product heat and leakage. Store batteries out of reach of children so that they are not accidentally swallowed. If younger children use the Cell, their guardians should explain the proper handling. Before using the Cell, be sure to read the user's manual and cautions on handling thoroughly. Batteries have life cycles. If the time that the Cell powers equipment becomes much shorter than usual, the Cell life is at an end. Replace the Cell with a new same one.

While the Cell pack is charged, used and stored, keep it away from objects or materials with static electric charges. If the terminals of the Cell become dirty, wipe with a dry clothe before using the Cell. Storage the cells in storage temperature range as the specifications, after full discharged, we suggest that charging to 12.8~13.6V with no using for a long time. Do not exceed these ranges of the following temperature ranges Charge temperature range : 0 to 45; Discharge temperature range : -20 to 60. Store less than 1 month : -20 - +60 Store less than 3 months: -20 - +45 Store less than 1 year : -20 - +25 ! Special Notice Keep the cells in 50% charged state during long period storage. We recommend to charge the battery up to 50% of the total capacity every 3 months after receipt of the battery and maintain the voltage 12.8~13.6V. And store the battery in cool and dry place.
