Hi, I meant it works then it doesn't work anymore then it works again, in short it's random and there doesn't seem to be any logic.
So when Therockinelvis wrote that he had experienced a strange breakdown in the past, I was wondering if the 3V battery is sufficient and if we shouldn't solder a 3.6V battery because the battery may not do well contact?

Stayouttadabunker:
I don't know...did you solder in your coin cell holder?
You checked it for continuity to the on-board circuit traces?
If you lose the internal accounting numbers and everything is reverted back to zero, then I would say that there's something wrong with the continuity of the coin cell holder mounting solder job than the voltage of the cell.
3 vdc is more than enough...I think you can drop as low as 2.78vdc, before the MPU shoots out a "Low Battery" message?
I don't remember the exact low voltage limit offhand, unless I look in a manual.
If you're NOT getting a "Low Battery" message, then something else is wrong.
Could be an MPU pin not getting a good connection, flakey power supply, or even the MPU itself.

Another thing to think of, is the machine works for about 6 hours.
Doesn't that sound like something is overheating?
How are all the fans in the machine?
Turn the power OFF and manually turn each fan you find in the machine with your finger or a pencil eraser tip.
What you are checking for is a fan blade that has waayy too much resistance.
The fan blades should spin easily and with hardly any effort - like as if they are brand new.
If the fan bearings are shot, that forces the PSU (Power Supply Unit) to try to keep up with the amperage to the fans to try to keep them spinning while under excessive loads.
After a while (in your case, 6 hours), because of the excessive fan resistance, the power supply gives up.
Six hours of old fans drawing too many amps - kills power supplies.
If you find a bad fan, then I'd be ripping the cover off of the PSU to look for bloated, swollen capacitors.... a definite sign of a PSU dying out.
