simpleavr 399 Posted November 8, 2012 Share Posted November 8, 2012 Currently, when the LEDs are off, my current is 0.9 microampere. 0.9mA stand by? that's way too much for a button cell application. w/ a CR2032, that would only give you 200-300 hours, or 10 days. do u need to run it constantly?

roadrunner84 466 Posted November 9, 2012 Author Share Posted November 9, 2012 I explicitly wrote it in full, instead of shorthand, to emphasize that it's 0.9 microampere (uA), not 0.9 milliampere (mA). So that's 10.000 days Quote Link to post Share on other sites
simpleavr 399 Posted November 9, 2012 Share Posted November 9, 2012 lol, my bad. saw it start w/ 'm' and trick me into thinking mA. well, 0.9uA is quite decent. i also use a button cell to power an alarm clock which runs for months (if i only turn it on briefly to read the time).
