After much testing of the battery, both load testing and specific gravity cell testing and I convinced myself this 6-7 month old battery is perfectly fine. Therefore,mthe likely culprit of the periodic click must be the relay. For $40 and a modest amt of effort, I was able to replace the relay and have tested the starter enough to know it is now fixed.
