@Bratt and Troy, Troy''s method is okay (except that I would use the battery itself as the power source). Charging current decreases at a constant charging voltage because the battery''s voltage is increasing (the battery is charging up). When the battery''s voltage is close to the charger''s voltage, current will be very, very, low (but not zero).
