Based on the forum, I’ve started a different practice wherein we all are posting questions and answering. This we are doing it MS-Excel as we do not have a Web based application. The response is pretty good. However, there are two specific questions that are classical and yet have never occurred to many of us. They are

1. How and when did the term “Battery Limit” come into practice?

2. Normally plants are designed for 20 years or 7000 cycles. But where did the magic figure 7000 come from?

Before posting here, I’d googled for both but the answers were not typical Piper types. I want to hear it from Pipers. Pipers, the more I see the more I believe, are a breed apart just like sailors.
