Charge/discharge cycle can be conducted for 3times before meeting the standards. (the same below)Low-Temperature Discharge:Standard charge. Keep the battery under -20±2 ℃ for 20 h.Then discharge to 2.0V at 0.5CCycle Life: Charge/discharge at 0.5C2 A /0.5C2 A ceaselessly until thedischarge capacity is less than 80% of nominal capacity.Recording cycle times. The cycle times ≥1800.Precautions for use:Use specific battery charger.Do not discard the battery in fire or a heater.Do not dismantle the batteryDo not immerse the battery in water or seawater, and keep the battery in a cool & drysurrounding if it is idle.Do not use or leave the battery near a heat source as fire or heater.Do not reverse the positive and negative terminals.Do not connect the battery to an electrical outlet directly.Do not short-circuit the battery by directly connecting the positive and negative terminalswith metal objects.Do not transport or store the battery together with metal objects such as hairpins, necklaces,etc.Do not strike, trample or throw the battery.Do not directly solder the battery and pierce the battery with a nail or other sharp objects.Do not use or keep the battery under high temperature (for example, under strong sunlightor in an extremely hot vehicle). Otherwise, the battery would be overheated, firing, out ofoperation or service life decreased.Do not use the battery in a location with high static or intense magnetic field. Otherwise,the safety devices may be damaged, causing hidden threat against safety.
