    If you change the battery when logging is due you will simply miss a record. Battery Life: A DL6 reading a full set of powered sensors once an hour (e.g. 6xML2, 1x Thermistor, 1x Rain gauge) should last over a year. This would be shortened by more frequent sensor readings, temperature extremes or prolonged communications.
