Error after "Reset-nvram" "reset-all" in open firmware

Hi, I my iBook Blueberry was having trouble correctly reading the battery I replaced my old one with. I found a site that said to boot into open firmware using Cmd-Opt-O-f, and it said to type "reset-nvram" and then "reset-all". After rebooting, I am presented with a sceen with a crossed-out circle.

I read that this helped many other people and figured i'd try it too. I would have to say my mac experience is limited as this is my first newer mac...

This is the site I followed... http://www.macintouch.com/laptopbatt.html
