One that charges fast (~4 hours or so - NiMH doesn't like to be charged slow), that has refresh/regeneration cycles, that recognizes faulty batteries, that shuts off after charging or keeps the battery on "support" charge, that has individual circuits for each battery, etc. This is an excellent charger, but it doesn't come cheap: ANSMANN AG: Energy 4 (ca. EUR 50,-) - but in the long run it sure pays off having a good charger instead of a crappy one, since you can use the batteries longer, and get more out of them.
