I didn't know to post this here or in the embedded forum. I figured it is more general so posted it here.
My microcrontroller project has a backup battery to power the RTCC in the event of a power failure. . I want to monitor battery level. I was thinking that I will need a load to get a true reading of battery status. The battery is going to be a 3V coin cell battery.
Should I measure across a load? If so what value resistor should I use?
