I have been doing some night runs on an old G7 at 60 minute intervals with 15 second exposures. So far however on a regular (old) battery I have gotten 186 shots over 3hrs 05mins, and one rodent.Display off. AFL = 1, Backlight = 1, retract = 60. Does this seem about what I could expect from a G7? Trying to go from dusk till dawn here but a long way off.
Also something that I wondered about: Are there commands for controlling (turning off) the LED's? I think there are 3 LED's on the whole time, which must be taking up some battery juice. While the camera is busy, an orange LED is flashing. Led's don't take a lot of juice, but is some power that could be saved.
Hmmm ... take a look at the first post in this thread. From your description, you are shooting with settings more relaxed than Test Suite Two, trial 2. I got four hours shooting that way with a crappy old A1200 and cheap AA rechargable batteries. You got 75% of that.Now take look at Test Suite Two, trial 4 (Display Off). In that mode, I got over 3x the time with the same camera and battery! Meaning you might be able to get 9 hrs that way.Your G7 has an OVF so you can use that mode. Set Turn Display Off to 1 and try it ?With the age of your G7, you might also want to think about ordering a new battery. I've had good luck with the non-Canon batteries. YMMV.
Are my settings relaxed or are these the most battery saving?

I was surprised the batteries were considered drained at 2.16V. I thought they could go down to under a volt.
Quote from: Paco on 11 / December / 2013, 22:29:21I was surprised the batteries were considered drained at 2.16V. I thought they could go down to under a volt.The battery voltage at which the script halts is determined by the value entered in the last user parameter - the one that says "Battery Stop Voltage (mV)". However, the Canon firmware may decide to shutdown the camera at a different point - usually at a voltage level decided by when the internal electronics will not longer work properly. I'm not sure what you meant by "they could go down to under a volt" as eventually all batteries can go down to 0 volts (obviously).
