I have a few CPS2 boards a was planning on changing the "suicide" batteries on all of them. Before I did I checked the voltages and surprisingly they were at 3.7v. I noticed that they had what I assume are the manufactured dates for the battery printed on them. All were 93-06 or 93-08. Is this the year and month?
My real question is if the battery is reading 3.7v do they need to be changed? They are almost 7 years old but are still reading good. Do these batteries suddenly drop in voltage or is it gradual.
I suppose the safe bet is to go ahead and change them. I just want some more insight to exactly how these batteries commit suicide.
All feedback is appreciated.
