It's use has seeped into actual practice though. (1300mAH sounds enormous compared to 1.3 AH to most people). "mAH" began as a marketing term used to make the numbers bigger. Real "mAH" value (as you are trying to use it) at 2.5ma might easily be 13000 vs. This is particularly true when facing a small draw like this. You can't use the AH figure to determine lifetime except as rule of thumb and then only for different cells using the same circuit.

What was the full scale reading for the meter when you took the measurement? Many meters have lousy accuracy if that 2.3ma lies in the bottom 25% if the scale. Might want to determine the accuracy of that number though. 2.3 ma seems a little high but then again may be normal. If anything, it needs to keep the clock running. I do use the AC supply every now and then so that may account for it. And I've had the camera since the end of November. I've passed my 1200th shot with the original 123's. So all you who-pile-on-to-the-technical-questions types, can you help me? I plan to send the camera back (once again) to sigma but want to know if I hav a camera that is that far out of the ordinary. That is why I was taking out the batteries that lead to the corrupted date a while back. That seems to be what I am experiencing.less than a month.

Based on this, if I did nothing I calculate that the batteries would use up all of their charge in around 36 days! That assumes that I have taken no pictures and no autofocus, that the battery manufacturers don't lie, and that the camera is able to work at the full range of the charge. The cr123 batteries from what I can seem to find have about 1300 mAh each. I need some feed back from you long term users.ġ) does anyone know how many milliamps their camera draws when it is off?Ģ) If you have your camera off and not being used for say a month, are your cr123 batteries seemingly as fresh as when you last used the cameraģ) I measured the draw an my camera using a milliammeterand get a reading of around 2.8 miliamps constant draw even when it is turned off. My sd9 seems to go through cr123 batteries * even when it is turned off.
