How many deep-charging cycles will your batteries handle before needing replacement? Where do the used batteries go for disposal? What is the cost of battery replacement? Are they portable? Could they work in an automobile?

I'm not asking antagonizing questions, believe it or not. I have an interest in the potential for electric substitution in the transport sector, and energy storage and portability are one major issue, along with range and environmental controls (heating in winter and A/C in summer). I see those as the major challenges right now for EVs. I really believe that costs can be brought down, but performance compared to gasoline-fueled vehicles is a tougher nut to crack.

The batteries are good for at least 15 years. For disposal, I may not have to worry about that, but there are failed mines in the area that have plenty of room. They are not portable, unless you have 2 men and a boy to carry each one. The entire assembly is on a skid and can be lifted with a fork lift. They will NOT work in an auto, either gas or electric.

Didn't see any antagonism in your questions. They were all legitimate engineering questions.

Remember that as a geek, I also use low cost, low energy consumption tech on the consumption side. The smaller the average power requirement, the smaller the PV system.
