Hi there ... I'm new in photography and considering to buy another batery for my D90.
Is there any do/dont for 2nd batery?
how I should store the 2nd batery?
I read/hear either in D90 manual or tutorial not to store the batery in fully charged or entirely empty (will reduce the storage capacity), so is 80-90% charged is a good percentage to store the batery?
I'm also thinking to buy batery grip, is that a good thing to have?
