There is a datasheet on their web site somewhere (I have the file but no link :( ). At 3 mA it should last about 200-300 hours before getting down to 6 volts. The rated capacity at 25 mA down to 0.8 V/cell is 595 mAh. Alex Kilpatrick wrote: > > > I thought that the typical capacity for a 9V battery was in the > neighborhood of 150 mA-H?
