Quiescent power
Power for quiescent current = 3.4 per day * 365
= 1241 mAHr per year
Total power consumption per year = 15 + 526 + 0 + 1241
= 1782 mAHr
Expected battery life is = 1700/1782 = 0.95 year
Note that battery life is shortened during configuration or diagnostics. When the serial cable is
connected to the 505U, the module does not revert to sleep mode and the power consumption is
considerably increased. These periods should be minimised if you are using a battery pack.
