Which shutter speed is hardest on camera mechanics?
Is a shutter speed of 30 seconds or a shutter speed of 1/8000th second harder on the camera (ie which one causes the mechanism to wear faster)?
I ask because on my D1s, if I don't use the EN-4 NiMh batteries at least every couple of weeks, I have to insert them into a camera, partially run them down, and then recharge them. If it's been a while, I actually do a complete run down before refreshing the battery. This is something that D2/D3 users don't have to worry about. But With NiMh, you have to do it.
So in addition to using the LCD screen and the DOF preview, I've been setting the camera to 30 seconds to try to run down the battery. I'm wondering if this is hard on the shutter/mirror mechanism. Hopefully not.

Probably none with recent cameras.
Most functions in modern cameras are controlled by a quartz oscillator which beats 32,768 times a second. 33 pules is 1/1000 with an accuracy better than 99%.
The time is controlled by the clock counting - the mechanical part is limited to first the shutter opening, and then the shutter closing. Tthe mechanical operation is the same for any shutter speed.
Photography is a bit like archery. A technically better camera, lens or arrow may not hit the target as often as it could if the photographer or archer does not practice enough.
