Battery Settings

A smart battery backup unit (BBU) can perform a learn cycle. The smart BBU module includes the battery, a battery gas gauge, and a battery charger. The learn cycle calibrates the smart battery gas gauge so that it provides a measurement of the charge of the battery module. A learn cycle can only start when the battery is fully charged.

The learn cycle completes the following operations:

•Discharges the battery to a predetermined threshold

•Charges the battery back to full capacity

A learn cycle starts automatically when you install a new battery module. Learn cycles for batteries in both RAID controller modules in a duplex system occur simultaneously.

Learn cycles are scheduled to start automatically at regular intervals, at the same time and on the same day of the week. The interval between cycles is described in weeks.

Use the following guidelines to adjust the interval:

•You can use the default interval.

•You can run a learn cycle at any time.

•You can set the learn cycle earlier than the currently scheduled time.

•You cannot set the learn cycle to start more than seven days later than the currently scheduled time.

To change the battery settings perform these steps:

1In the AMW, select Storage Array→ Change→ Battery Settings. The Battery Settings dialog is displayed.

2In Battery location, select a battery.

3Check these details about the battery:

•Battery status

•Battery age

•Days until replacement
