With rechargeable batteries I get 400+ pictures with our S600's. I've not tried lithium batteries and alkaline batteries will not last long at all. I have several trail cams with real digital cameras in them and use rechargeable batteries in all of them.

I've had a camera with a yeti board for a couple of months now and have not had to change the 9 volt battery yet. They should last 4 to 6 months. Get a new Duracell or Energizer 9v battery and see how long it lasts. If it is still using batteries that fast then there is something wrong and you should check with the manufacturer.

I do have two Pixcontroller boards that use up 9v batteries in about four weeks, while the other two boards I have from Pix worked fine. I couldn't find out why these boards used up batteries so fast.
