Description
If the above event is registered, check the Cache Mode (current value) of the RAID Controller with Universal
RAID Utility.

If the Cache Mode (current value) is Write Back, use the battery as is because there is no problem.
→
If the Cache Mode (current value) is Write Through, the battery refresh operation causes the battery
temperature to rise temporarily. This event temporarily stops the refresh operation, so the battery
temperature drops and the refresh operation resumes. However, it may take time till the temperature
drops. After the refresh operation is completed, the Cache Mode (current value) changes to Write Back.
If the Cache Mode does not change to Write Back although 24 hours have elapsed, the battery may be
faulty. Replace the battery.
