Clock Battery

[squarerigger]

I was doing some reading about digital cameras (always a danger) and ran across info about a "clock battery". Much like the internal battery in a computer that runs the internal clock when power is off. Does the K10D have an internal clock battery? Seems to make sense to me. Where is this beast and how do you know when to or how to change it? Is this a repair facility job? Tried to do a search on this and came up empty.

Thanks - Gary

yeah,
i've been wondering that for years.. my fuji has an access..

When your camera doesn't remember what day it is, you'll know the battery is dead. But, if it is like other electronic device with internal batteries for memory, I have seen some of those lasting up to 21 year in telephone system, so you can sleep in peace!

Hmmm...the one in my 300D is right next to the main Li battery, clearly marked.

On a side note, I've never replaced it, nor have I replaced a CMOS battery in a computer. Don't they shut off when the cam/comp is on? Thought so...

I've had to replace 'em in laptops, but haven't worried about them in desktop systems in about a decade.

In September 1986 I started an AA degree program that required a scientific calculator. I bought a Texas Instruments TI-35 Plus. The book said the batteries would last about 2 years with daily use.

The print is worn off half key faces and the folding case has seen better days, but it's still chugging along. I replaced it with a solar powered one 4 or 5 years ago, only because it was a pain having to look in the book to see what keys were what.

I know the ist D had a clock battery, but I do not believe subsequent models have one, or at least one that is serviceable.

I think they have mostly done away with a separate clock battery and use some kind of "reservoir" (capacitor?), which pinches a bit of juice from the main battery to keep the clock counting while the main battery is taken out.

That leads to the question: Does anyone have a K10 wiring diagram? Then we could see what's really going on.

(Or someone could take their cam apart...not it)
