Resmed A10 Motherboard Battery
#11
RE: Resmed A10 Motherboard Battery
I have not studied the workings of my Resmed S10 Autoset, but I am an electrical engineer with experience with microprocessors and embedded control. Battery backed RAM to store parameters was common in the 1900s, but not today. Modern microprocessors include nonvolitle, or electrically erasable memory for parameters.

The real time clock does need a battery so that it can run with the unit unplugged. This will be a lithium coin cell. If the design life is 20 years or more, then they assume the battery never needs replacing. That's why it is not designed for easy replacement and the manual does not tell you how to replace it.

Thanks for helpful replies (again). The pdf of internals shows a battery (BAT200) on backside of the motherboard. I guess I just hope when I need the backup machine that the battery is still functional.

Glad that the PDF helped. BTW, BKeeper.... does that mean BeeKeeper by chance?
If so, we started in Feb.

Yes, ATSC, I am a long-time hobby Beek  Smile
Best of luck - for me, it has been interesting and quite a learning experience for more than 30 yrs now.
