Battery Notes
Each battery works with a controller. If the battery is present in the subsystem but
the corresponding controller is not present, the battery will not appear in the
interface.
If a battery does not reflect normal conditions and it is not currently under
reconditioning, run the Recondition function before you replace the battery. See
"Reconditioning a Battery" on page 90.
Reconditioning fully discharges, then fully recharges the battery. During
reconditioning, if the Adaptive Writeback Cache function is enabled, the controller
cache is set to Write Thru. After reconditioning, the cache is reset to Write Back.
See "Making Controller Settings" on page 83.
If a battery reaches the threshold temperature while charging or discharging, the
charge or discharge pauses and the blower runs at high speed until the battery
temperature falls below the threshold.
If the battery does not maintain normal values after a Recondition, replace the
battery. See "Replacing the Cache Battery" on page 212.
VessRAID automatically reconditions the battery every two months. To set the
schedule, see "Scheduling an Activity" on page 54.

runs a recondition on the battery to verify it. If you restart the subsystem or
