Would the cache batteries have held properly from whenever the UPS
batteries went dead until 1pm?
Yes, the cache batteries should have held the contents of the write
cache for the few hours you were without power.
The adapter slot must be powered on in order for the batteries to charge
from electrical power. Depending on system type, this may mean the LPAR
must be active (to DST at least) for the trickle charging to occur.
With the cache batteries in normal condition, the contents of write
cache should not be lost if you have to go multiple days without power.
