7.5 Battery storage
The battery should be stored in an area at room temperature with a non-condensing relative
air humidity—see specifications on the MiR website. Temperatures and humidity below or
above the specifications will shorten the service life of the battery.
The battery should not be exposed to nor submerged in any liquid as this may damage the
battery.
Charge the battery before storage to preserve the service life of the battery.
NOTICE
If you store the battery for a longer period of time when it is almost depleted,
you may not be able to get it running again. Contact your distributor if this
occurs.
To preserve the battery, disconnect the battery from the robot before storing the robot.
Power save mode
If the battery is not used for a period of time, it enters Power save mode. When the battery
is in Power save mode, it will not power the robot until the battery is activated again.
To activate the battery after it has been in Power save mode, disconnect it from the robot
for 30 seconds, reconnect it to the robot, wait 30 seconds, and then turn on the robot. If the
robot cannot turn on, contact your distributor.
The amount of time it takes for the battery to enter Power save mode depends on the state
of charge of the battery. The best state to store the battery at is when it is 80% charged.
provides best practice values for storage time and the time it takes for the battery
to enter Power save mode depending on the battery percentage.
