Interesting question, I never though about if there is any way to test a black holes charge.

Calculate the black hole's mass. Put a charged particle somewhere in the vicinity of the black hole. Measure acceleration. Do math.

That much is obvious given an assumption that charged fields work proberly through a blackhole, which was not obvious particularily given aljandro's statement. After confirming that the charge of a blackhole can interact with being impeded by the singularity, there are a lot of obvious ways to check the charge

Will that work? Or to put it particle-ish-ly, how is the information about a charge inside an event horizon able to escape?
