storage:
1. Use at temperature below 40°C,charge fully prior to long storage periods or if it has been stored for more than three months
2. If you find any single battery voltage is under 2V at room temperature,the battery has been over-discharged or is self- discharging due to some defect/parasitic load. Discontinue use until the fault can be corrected and the battery be recharged
3. Store in an open,well ventilated,dry,clean area, between -20°C to 40°C for maximum life. self-discharge will accelerated at higher temperature
4. Don’t expose the battery to extremes
