Thank you. This is fantastic information that is *not* in the manual. I bought an unnecessary main battery, but this resuscitated my camera on a trip.

Thanks! David D.

All the other advice I found says to remove two screws, when it's really as simple as you show here. Thanks!

This was so helpful, thank you! Also if you are in a jam and do not have a CR2016, you can use a CR2032 directly without using the normal battery tray.
