The reason why the batteries Gold/Silver/Crystal games die is because of the clock function. To maintain the time in the games, the battery constantly has to run.
So to answer your question about whether your Blue and Yellow batteries dying... the answer is no they won't die, at least not for a long time, since they do not have internal clocks
On a side note, I have a Crystal cartridge which needs a new battery so I will use that opportunity to have pictures exclusive to this site. I am also considering creating a video tutorial which I am sure will help some people.
