Battery backup unit
To access the battery backup unit page, select
Controller > Configuration and then click the Battery Backup Unit button.
The batteries have usually a life of 3 to 5 years. You should enter the battery
installation date in the fields provided on this form. If you change the batteries
you should also change the installation date setting. When you confirm, the
dates will be stored to memory on the shelf back plane. Setting the battery
installation date also sets a flag. The flag is not automatically activated when the
date expires but it is a convenient device for making remote queries without
having to look at the date labels on the batteries themselves.
An accurate display of the battery charge level is only given when the battery
has been reconditioned.
