Damn it! I should have taken pictures of my battery holder project for the blog. I wasn't even thinking about poor old mondocool.net. Well I do plan on replacing the battery in my Legend of Zelda cart too. It still saves but I've lost a few saves while trying to get the game to work and killed the save in the process. It was the first NES game I bought back in 2000 when I bought my NES so I probably wasn't in the habit of cleaning every cart I get. Last night I did clean it and it was filthy. So since there's no save to worry about I'll take it apart and put in a new battery and give it a more thorough cleaning. So I'll make sure to document that.
