I have two suggestions for you, Robert, before you take the camera back to the store: 1. Buy lithium batteries - I know, very expensive, but not relative to the equipment you're using. Also, they will last SIGNIFICANTLY longer than others; you'll recoupe your cost in no time. I have run up to about 100 rolls of 36 on a single set of liths. 2. Set your custom function #15 (Time delay for auto meter-switch-off) to 4 seconds (default is 8). This can add quite a bit to your battery longevity. Good luck. Let us know how it turns out. >------------------------------ > >Date: Sun, 22 Nov 1998 19:05:06 -0500 >From: Robert Body <[EMAIL PROTECTED]> >Subject: F5 draining batteries [5] > >I had my F5 for a month now, and I have gone through 4-5 sets of batteries, putting in brand new ones every time. I have only taken 6-8 rolls in total. While it is true that I leave the camera on when I am just walking for hours, I didn't think there would be a big drain if the camera is ON but not in use. >With slightly cold temperature, like 32 F, the camera batteries just give up. > >Today the indicator was showing full battery power when I started taking pictures. [batteries have been in the camera for a while]. Within an hour, and 10-15 pictures later [but camera was ON all the time], I saw the camera power drop to half, and then the battery sign was blinking and the camera would not take any more pictures. The temperature was close to 32 F. But this is not cold. -20 F is cold. I put in new batteries, and all was fine. I am using Alkalines. > >So, I see 3 causes > 1) battery drainage Nikon problem - but this problem has been known for a long time and should have been fixed. My serial # is 3114130, bought 1 month ago. > 2) battery drainage when camera ON but not used - isn't this really 1) ? > 3) crap batteries. These I bought from the camera store, they have a less known name. I should try Energizer/Panasonic/Duracell perhaps? I have only used this one brand since I bought the camera. > >Has anyone seen a problem with (a recent serial#) F5 draining the batteries? > >Robert >[EMAIL PROTECTED] > > >------------------------------
