How does the EOS 7D Mark II keep the time and date without a removable battery?

When I owned the Canon 7D it had a small battery that was used to keep a few settings and also the Time and Date. I now have the 7D2 and there's no such battery. How is the clock information stored without that battery?

Cheers,

Greg

The 7D2 uses an onboard circuit that is charged by the main battery.  It’s probably just a capacitor on the circuit board.  Speedlites have similar circuits to power their strobe.

Eliminating the battery means one less part to replace periodically.

Many (most?) cameras have an internal, not-user-replaceable battery or a capacitor that is kept charged by the main battery. No more bothering with having to replace a battery.

The problem comes when the internal battery/capacitor wears out and no longer recharges. Then you need Canon or a good service tech who knows what part to replace and how to get to it. Or you just lose date and time on your files whenever you take the main battery out. 

The date/time battery is only that, as far as I know. Doesn't affect anything else.

Thank you - that explains a lot.

Seems like a good move by Canon. Thanks for the help - appreciated.

It's a move years ago by most, if not all, camera makers.
