Battery Life
(1) The battery life changes depending on many factors. The graph above shows how the
performance of the battery deteriorates on different current at the same temperature. The
graph above illustrates four discharge curves on different current and the effects.
According to the testing result shown on the graph above, when the power consumption
of an absolute encoder is 65uA or lower, if the voltage of the battery keeps 3V or higher,
the expected battery life is about 21900hr, approximately 2.5 years
lowest voltage level of battery for an absolute encoder is set to 3.1V.
(2) The battery life expectancy is about 5 years and is able to provide 3.6V or higher voltage
under normal temperature and humidity conditions.
The battery life was measured when one single battery box is connecting to
