I'm using my GT A6 charger to cycle the 7 cell, 1000 mAh, NiMH flight pack from my NitroPlanes PBY Catalina. I'm monitoring the process on my computer using the provided "Charger" software. All seems normal and predictable except for one characteristic that I don't understand.

While charging, the charge current drops briefly to zero every two minutes (variable) or so, then switches back to my selected charge current of 0.5 Amps.

Anyone know what's going on? Is it checking for something? It charged the pack to 10.41 V before switching to the discharge part of the cycle.

Just curious, thanks,

Frank
