Maybe the simplest option is just to get some decent
rechargeable batteries and just keep swapping them over say once a month.

Why not get a couple of cheap CB radios, one in the house with a tone
generator wired between the bell push and the audio input, and one in
the shed/whatever. Or the PMR446 walkie talkies might have enough range.

Or run a speaking tube from somewhere near the existing bell/sounder to
the shed?

Although common it frequently goes undiagnosed.
