Calculation the battery capacity
4 main factors impact the battery capacity/lifetime:
Constant load: about 10µA for the current version Mode „Sleeping“ with
periodically checking the radio. So 1 mAh is good for ca. 100 hours of „Sleeping“
Pulse load: about 9mA for 0.2 seconds per measure, so 1 mAh is good for
ca. 2000 measures
Self discharge: about 10% after 10 years
Temperature cycles: difficult to predict, could be up to 50% (worst case)
ca. 2000 measures
Self discharge: about 10% after 10 years
Temperature cycles: difficult to predict, could be up to 50% (worst case)
As a rough estimation: Theoretically 2400 mAh are good for >25 years of „Sleeping“ or
>4000000 measures (this is almost 500 years for 1 measure per hour), if no self discharge is
assumed. Practically we normally calculate only with 1/3 of the capacity (the rest is for
spare): For 1 measure per hour each year requires 5 mAh, with the rest of 2400 mAh / 3 =
800 mAh still almost 8 years of operation should be possible. Hence we would recommend to
replace the battery with these settings after 5 years or later, if „temperature drops“ for cold
phases rises significantly.
