Should I store a completely charge http://www.nikonusa.com/pdf/manuals/tnirp/dslr_accesories/DSLR_Batt/EN-EL3e.pdfEN-EL3e battery (D200) on the charging unit? That is the charger is unplugged and stored in my camera case, to save room. Does storing the battery on the charger cause it to discharge faster? Any other things that I should be aware of?
