Not a bad idea tagging by first letter, although I'm not sure how useful that would be. If I visit the site and want to browse for batteries, I may not know all the brand names. Might be a good first start though. Regarding blank pages: those pages are blank for two reasons. First, I just launched an updated version of the site. I haven't added any redirects from old to new yet. The second is that I accidentally let Google index those pages in the first place. As you mentioned, Google doesn't like thin content. I received good long-tail traffic until Google (rightly) booted my pages down to the third or fourth page. I now have a robots.txt in place to stop it, and don't particularly want Google to index my product pages at the moment. Moving forward, my plans to make product pages better involve various parametrics (which I'm working on). Being able to play with interactive graphs of various parametrics, such as mAH/weight or discharge/cost ratio. Then generic sorting based on price, availability, etc I'll selectively unblock certain product pages and allow Google to crawl them when they are more useful to the user. Basically, Octopart is my role model. Backlinking strategy right now is contacting bloggers and podcasters to get my site into the hands of a few hobbyists, so I can start to generate feedback. I also got a mention on Hackaday a few days ago which is helping. I have a few features planned which will incorporate more sharing.
