iCharger Duo Balance Circuitry Repair Service

A pretty well known issue on the iCharger Duos (406 Duo, 308 Duo, 4010 Duo) is that balancing will never complete and the charge cycle never completes (or takes an extremely long time).  You will typically notice a very low actual charge rate (usually less than 1A, down to a few dozen mA after an extended time) and one of the cells showing as being discharged at full power.

This is normally caused by failure of a transistor in the balancing circuitry of the charger.  Failure can be caused simply by age, or by a short circuit or other fault on the balance port(s).  The failed transistor means that even though it is telling the cell to discharge at full power, the transistor is not working and thus no discharging is actually occurring.  Since the charger is trying to also balance the cells, if it's unable to discharge a cell the charge cycle will never end (unless you have a charge time limit set up).
