Sounds like you have the same problem I have.
I replaced the battery on my A3K but on a re-boot
it lost the time and date.
I had to open the machine up again for another
reason so checked out the battery while I had it
open.
The voltage to the battery circuit was dead.
So the only way mine will work is to trace the
circuit find where the circuit died.
I'm not that good, so its just dead.
You could download 'Atomic Clock' from Aminet
and set it up to set your clock whenever you go
on-line.
