Just recently tore down a build and I have 3 D3100's and a D2700 with one of the 1215 intellichargers. My question is what's the best way to store them? Acceptable temperature range, do they need to be on a shelf or cardboard or anything? Is the 1215 good enough for charging all of them? Can I just keep the charger plugged in for the couple of months they will be sitting? Thanks in advance.
