Can someone tell me about the battery life of 2cr5 batteries in Canon eos 3 body?
Is the body using energy even if it is turned off. I am only asking this, because I put a new 2cr5 battery inside the body and I havenīt used it for a month, but when I turned it on after a month, the battery was completely empty. Is this normal?
I had it checked and everything seems to be OK. I just find it odd, because I can leave the same battery in the eos 50e (elan IIe) body for a year, and it would still be full.
I can tell you exactly what the problem is. The answer and solution was discussed in DPreview about 3 years ago, and at home, I may have a copy of that thread. I owned an EOS 3 for about 3 years - fabulous, fine camera!
Very rarely, this camera will have an internal current leak when the camera is shut off and stored. That person did an electrical study and proved it.
All you have to do when you're done from the day's shooting, is remove the lens, and turn the camera off. Then, with the lens off, turn the camera on and then back off again.
I've never used a 2CR5 in my EOS 3, but I get 75-100 36-exposure rolls off 8 lithium AAs in the EOS3/PB-E2. Also, they seems to last for years if not used.
When I used the 2CR2 in my EOS 5 it only lasted for 20-30 rolls and would slowly lose power if left sitting for a few months. My old Elan (EOS 100) was about the same.
Sounds like a problem to me. I had the EOS-3 as well, and I was always amazed at how many rolls of 36 I got, even when using IS and highspeed bursts. I loved that camera. I usually got between 70-90 rolls on one battery.
I think the internal leak is a design flaw. But it is rare enough that it doesn't seem to be a big problem. I don't think it will appear in another malfunction in the camera.
I think all EOS 3 will show it sometime in their life. I shot very few rolls, and I got about 40 rolls per battery over about 1 1/2 years. Then I put in a new battery, shot 2 rolls, and the new battery failed the next time I picked it up. After knowing about the problem and the fix, it never happened again in my camera.
Removing the battery will definitely fix that problem, but I don't think you have to do that.

100 rolls you are sh!tting me right. I would get maybe 10 rolls from NiMH, 2500mAh. Never tried the Lithium as they were $8 each at the time.
Pixel Perfect, do you leave your NiMH batteries in the battery pack after shooting or do you take them out? If you leave them in, will they get empty soon?
My EOS 3 has had the same battery for at least 8 months, been sitting most of the time, but I've run about 6 rolls of film through it. It's still showing pleny good at the moment. Are you running the power-drive?

I leave them in, but I thought they self discharged even out of the pack. This is the bug bear of NiCD and NiMH. I can fully charge spare batteries and after a month they a way down just sitting in their battery case.

Do you happen to know if that flaw extended to the 1V ? I've had the similar low number of films per 2cr5 on both the 3 and the 1V, to the extent that using the PB-E2 was mostly appreciated for providing extended battery life rather than faster shooting. I never shot a lot of film at one time so there was often days or weeks between shoots.
