I thnik the only thing I would add to Bob's post is, if you do remove them - put them in your camera bag / with your camera...
There is nothing worse than picking everything up, out you go and start to shoot only to find the card is next to the PC at home or battery is sat near your charger !!!
You'll only do it once mind...![]()
It's one of the reasons to have spare batteries & cards.
Whenever you swap an empty battery or full card out, put a fresh one in - so worst case is you are only missing the spares.
