Trying to charge these brand new just received Sanyo 3500mah NCR18650GA batteries with my Nitecore I2 and I4 chargers. I was advised that they were shipped uncharged and had to be charged before use. I also tried charging the batteries one at a time in each of the chargers as well for a number of hours but they don't get past the first charging indicator light. The second of the three lights flashes but that's as far as they go. Am I missing something? Are the chargers not compatible or am i not waiting long enough for the second light to stay on? I stopped charging them and posted here because I noticed the chargers were heating up as well. For the record each of these chargers have worked flawlessly up to now with all my other batteries. Any help would be appreciated thanks!!
