Don't get upset when I say this. I think you need to stop making threads. You are going to get someone killed.
Brown bears and black bears are nothing to play around with. They have very thick hides and very thick skulls. They can be very aggressive and they
will kill you if threatened. A baton will have no effect whatsoever.
You would be better off taking a spear or long knife with you. At least then you will have a slim chance of killing that sucker.
