Sanyo MQN06 charger

Sanyo MQN06 charger included in this package only charges in pairs. If you just put in one cell, NOTHING happens. It is a semi-smart charger, meaning that it monitors the combined voltage of two cells, and stops charging when AT LEAST ONE cell is fully charged. This prevents over-charging, but one cell may be under-charged (if you group two cells of different capacities in a pair). Is the MQN06 good enough for your application? IF all your battery-operated appliances use even number of cells, AND you only use idential cells in them, AND you make sure not to mix-up cells from different appliances, THEN it is acceptable to use this charger. Otherwise, get at least one charger that can handle individual cells. For example: Sony Cycle Energy BCG34HRE4KN Quick with Refresh Charger and 4 Pre-Charged 2000 mAh AA Batteries
