With laptops I've been told that it is a good idea to completely drain the battery and then charge it up to full again every month or two. As I've understood, if you don't do this the battery's capacity slowly diminishes.



With a miniDV video camera I once had I got similar advice and in fact the battery charger had a feature where I could select to either (a) just charge the battery OR (<img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/cool.gif' class='bbc_emoticon' alt='B)' /> discharge and then automatically recharge the battery.



I was curious if there are tips such as these, that I should know about regarding the battery used with the Canon 5D mark ii.



The only instructions I've come across so far (in the camera manual) say to remove battery from camera when camera is not in use; and that its best to charge battery before use, regardless if you haven't used it since charging it last. Apparently the battery drains a a bit when not in use and even more so when in the camera.



Is there more advice I should keep in mind - battery-wise? THX <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/cool.gif' class='bbc_emoticon' alt='B)' />
