(1) The above figure illustrates the discharge current curves measured in the constant current
test. According to the five curves shown above, if the voltage of the battery keeps at 3V or
higher, the expected battery life is as shown in the following table. Therefore, the lowest
battery voltage level for an absolute encoder is set to 3.1V.

(2) The battery voltage can keep at 3.6V or above up to 5 years when stored in a cool dry place.
Note:
1.
The battery life expectancy is measured with a test using a servo drive, a motor, and a single battery.
2. The current consumption is nearly 0 when the absolute origin coordinates are not established.
Once you established the absolute origin coordinates, the battery power consumption starts.
To avoid battery power consumption when shipping the machine, it is recommended that you leave
the servo drive and battery disconnected, or leave the absolute origin coordinates unestablished.
