I need canon eos 40d date and time battery holder

Can anyone help with this? I wonder where I might be able to find it?

Greetings,

You can try eBay or see if you can find a broken 40D available for parts.

You don't even need the date/time coin battery. The main battery provides the power for operation. The date/time coin battery just remembers the date and time so it will reset the date/time each time you turn it on.
