You may be right, Jim. And I may have posted victory too soon. With the AA's installed and the EFlite adapter plugged in the charging indicator did not shut off within a reasonable time. Charging indicator did not come on at all without the AA's installed.
I unplugged the charger and let the battery charge from the AA's. The light went out per the normal charge cycle. I have not seen instructions as what to do with the AA's when using the adapter. Point that out if you can find it.
I'm figuring that I either have a defective charger, I damaged the charger using a 650ma adapter(unlikely), or I'm not doing something right.
