My Nikon EN-El3e batteries when put in charger would blink orange only 4 times then go blank. Since there is some electrical system that needs to reset I would have the battery touch the charger connections for 3-4 blinks then connect again and again and again until there is enough charge to reset the battery. a 20 amp circuit US may be better than 15 amp electrical circuit. Doing this to 2 batteries they came back to life and recharged- Voila!
