We recently got a five-battery charger, but before we just had the chargers that FIRST gave us. The new charger helps, but even without it, we always just had the batteries plugged into the charger under the table. On the floor, we have a piece of tape that reads "Charging... Charging... Charging... Charged!" and we line up the batteries in order of chargedness, with any and all completely charged batteries all on the Charged! end.
On a completely irrelevant note, I think this is not the first time I have written and posted this.
