battery learn cycles, enable automatic learn cycles. To choose manual 
battery learn cycles, disable automatic learn cycles. 

If you enable automatic learn cyles, you can delay the start of the learn 
cycles for up to 168 hours (7 days). If you disable automatic learn cycles, 
you can start the learn cycles manually, and you can choose to receive 
a reminder to start a manual learn cycle. 

6.1.3.2

Setting Learn Cycle Properties

To set the learn cycle properties, perform the following steps:

1. Click the 

Physical

 tab to open the physical view.

2. Select the BBU icon in the left panel.

3. Click the 

Operations

 tab.

The BBU operations appear, as shown in
