I like the idea of the coloured tapes.
Did you consider placing matching coloured tapes on the chargers / appliances? So the Dewalt 12V Nicad would have a piece of yellow tape on it, matching the yellow tape next to the plug. So you look at the appliance and know which plug belongs to it. Might be faster than looking up the chart every time.
Just my penny's worth.
When my time comes, I want to die like my grandfather did - quietly, and in his sleep - not kicking and screaming like the passengers in his car.
