[comp.sys.amiga.programmer] My Hardware clock

OK, This may be a problem which is described frequently, but I
searched, and could not find any info on my specific problem.
I have an Amiga 500, and I have been having trouble with my battery backed up clock.
I am familiar with the ways that out of control programs can screw
up my clock, and on occasion I have had to reset the clock after
such a wild program stampeded over it, however I have been having
another problem which arises quite frequently, namely that
my clock will sometimes return a partially correct date and time,
but part of it will be wrong.  For example, the day of the month, year, and 
hour may all be correct, but the month will be wrong.  Or the date
might be right, and the minutes, but the hour could be off.  I have
tried using setclock reset repeatedly, and I tried a small program
which was supposed to fix any clock "virus", however this program
returned a message saying that my clock was wrong, but had been
corrected.  It continued to give this same message every time I
ran the program.  This memory expansion/clock board is not an Amiga
model, but a third party model which has served me well for several years.  
Could the little battery on the board be going bad?  If so, how feasable
is it to repair something like that?  Where exactly should I look
for the clock's registers, and how can I read them?  This problem is
minor, but very irritating:  I rely heavily on the time and date
stamping of my files, and I have had problems because of this more than once!
Any help will be most appreciated!
