=20 I thought that the typical capacity for a 9V battery was in the neighborhood of 150 mA-H? I am running a test on a ciccuit that consumes around 3 mA 99% of the time, and so far I it has been running for almost 4 days (almost 300 mA-h). I am using a new Energizer 9V battery. Does anyone know any real specs on an Energizer? =20 Thanks! =20 Alex -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
