Also, check what message is being written into /var/log/messages by apcupsd.  If
it's still saying, "replace battery," then it's probable that the UPS didn't
"sense" the new battery and you just need to update the battery date on the UPS.
 No sure why but logwatch doesn't consider any of the apcupsd messages as
reportable so you have to look at the log file to see what the UPS is reporting.

If you're lucky, the above is all that's going on and the easy fix is to update
the battery date.  I just had my APC UPS blow a battery sensor and decide that
the battery was no longer present only to then immediately decide it was indeed
there and cycle through battery attached/unattached continuously.  APC is
sending a warranty replacement UPS.  Oh, and the UPS blinks the replace battery
light whenever the battery status goes to unattached.  ARGHHHHH!!!!
