AS OLD AS THE UNIVERSE. “For a GUT monopole, Mmon ∼ 1017Gev, we find that for Q > 106 the lifetime is larger than the age of the universe. We get a similar answer if we assume that the unit charge magnetic black hole has a mass near the weak gravity upper bound. Of course, if the unit charge monopoles are lighter, then one would need to make the charge larger, and the black holes bigger, to ensure long lifetimes.” (Don’t worry about the symbols, get the gist).
