Storing the storage system

If the storage system does not receive power for more than six months, the
battery can become discharged and possibly damaged. To avoid this
situation, charge the battery for more than three hours at least once every
six months.
Note: Do not store the equipment in an environment with temperatures of
104ºF (40ºC) or higher because battery life will be shortened.

If the storage system is connected to a PDU, you can stop the power
