I recently began having problems with the battery backed clock in my Amiga 500.
The clock is in my M501 512K memory expansion board from Microbiotics.  When I
reboot, cold or warm, I get a Battery Backed Clock not found error when I do a
"setclock opt load" from my startup-sequence.  I removed the M501 and checked 
the voltage on the battery with my trusty voltmeter and got a reading of 4.25V.
Is this enough?  Should it be 5V?  Is my battery bad or is it something else?
I have owned the M501 and my Amiga for 2.5 years and have never had any problemslike this, so any help would be greatly appreciated.  Thanks!
