ds1904

Anyone used one of these?
What I'm trying to find out is what happens if power is removed, does the time stay stored or does it lose power?
also anyone seen these anywhere in UK?

The DS1904 iButtons have internal batteries good for a nominal 10 years. You can open them and rebattery if needed but your labour will cost more than a new iButton.
