Battery lifetime estimation
The value displayed in the “ADT1 Configuration” and the “KOLIBRI C
loud
“ is the battery capacity calculated by the ADT1
as a percentage of remaining capacity. It is recommendable to change the battery if the value is less than
20%
. Once
the battery has been changed the value is once again shown as
99%
.
NOTE:
Please note that a battery change or disconnection of the battery always results in resetting the capacity indication to
99%! For this reason, the battery should be disconnected for battery replacement only.
The calculated lifetime in the table below indicates how long the battery can last in different conditions.

NOTE:
The calculated lifetime values in the table are merely calculations. External conditions (like temperature and storage
time) have an influence on the battery capacity and its lifetime.
