I have had very bad luck with batteries from Radio Shack. If you look in the review section on the batteries, (Radio Shack site), other people have been unhappy with them as well.

Try here: www.cheapbatterypacks.com Click on "Loose Cells" and then "Nimh".

I've gotten glow batteries from him, batteries for my starter setup, etc. Good prices, good service, good products from my experience.
