Recycling of Battery
Dispose of the used battery appropriately in accordance with the laws and acts of your
national or local government. If you cannot dispose of a used battery properly, please
inquire of your EPSON robot supplier how to dispose of it.
Charging Battery
Turning ON the Controller will automatically charge the UPS battery.
To completely charge a discharged UPS battery, turn ON the Controller and keep it
energized for at least 2 hours after the backup operation.
Life Cycle of Battery
The battery is expendable. To maintain the Controller function, make sure to replace the
battery regularly and appropriately for the use condition.
The life cycle of the battery depends on the ambient temperature, number of backup cycles,
and backup time.
To prolong the life cycle of the battery, complete the shutdown of Windows within 2
minutes.
Relation between the life cycle of battery and the ambient temperature:
When the ambient temperature is 20 deg.C: approx. 10 years
When the ambient temperature is 25 deg.C: approx. 8 years
When the ambient temperature is 30 deg.C: approx. 5 years and 7 months
When the ambient temperature is 35 deg.C: approx. 4 years
When the ambient temperature is 40 deg.C: approx. 2 years and 9 months
Note that the life cycle above is for the reference and it does not guarantee the backup in this
period.
Also, the battery must be replaced before 10 years in any circumstances.
