any nimh charger can charge any nimh battery, but only thing difference is the time. if you use a energizer charger to charge a 1800 will take a longer time than a GP fastest charger.
Del_CtrlnoAlt, you can't generalise. There're some timer-based chargers that cut off charging at fixed time and won't charge the newer high capacity batteries fully. Intelligent chargers (with voltage/temperature sensing circuits) on the other hand should be able to charge "any" NiMH batteries.
