[RE-wrenches] Help me do the math: amortized cost per amp-hour

I agree with that for floating flooded, wet cell lead antimony batteries... but flooded lead calcium cells are a more appropriate choice for floating banks on grid ties with backup. No cycling is necessary.

We all learned that whenwe continuously floated battery banks with the old SW inverters. Banks that arealways floated only seem to deliver about 70% of the expected life. Moderatecycling is good for a battery.
