be easier.

Are there any out there?

I have a good old "ding-ding" chime, with illuminated push button and CU
mounted transformer, don't know if there's an easy way to piggy-back
additional sounders off it though.

it's worth pointing out that the bell push batteries
last pretty much the battery shelf life in normal use as they're only
drained when the button is pushed.

How does that explain every battery powered one I ever try to use being
flat?

Doorbells used to use massive batteries decades ago. Those lasted many years, basically shelf life. Now that they use tiny AAs or similar of course they don't last well.

My computer is spying on me. I just got this recommendation in Ebay, I guess you could make a doorbell out of it:
