Cost about $2 per cell on line from China, but you are getting a hell of a lot better battery. Just have to be able to solder.

Where are these studies that show these cheap chinese batteries are better than once I get from Radio Shack and install?

The study is probably his initial cost assessment, which stuff straight from china usually starts great, but I don't even see any links to anything specific. For all we know they are selling potatoes...

Just personal use. I have not looked into it but I bet they are all Chinese batteries. Bought mine off of Ebay. The highest powered ones.

I'm going to kindly ask you that you please refrain from making any kind of product recommendation unless you have information about it. And posting on other peoples profiles hinting at things I won't tolerate either.
