Chris, I hope your wrong, but I'm giving the two receiver packs a good charge all day long. We'll see tonight. Interestingly, the ECU packs for the turbine which would not be connected to a regulator are both in tip top shape. That would seem to support your statement.

That being said, the battery that was blinking on the charger was not connected to anything (it was in a drawer) and I know it was charged when I put it there.

If setting these batteries aside for a few months can cause this problem, I might go back to Nicads as these batteries are too expensive to have them go bad by simply setting an airplane aside for a couple of months.

Hmmmmmmmmmmmm.
