Ease of getting them. O can get 9V
(PP3/006P/6F22/whatever they're called
this week) batteries almost anywhere. I don't know a UK supplier for
45V batteries (even the 22.5V ones [1] are getting hard to find). I
don't fancy gettign a couple of batteries shipped acorss the Pond every
time I need them.
Well, now you do!

I recall reading about a turn-of-the-century pipe organ that used wet
Leclanch? cells to power the key action (before being boosted by
pneumatic means). The zinc anodes were attached to a board that was
operated by a bellows. The anodes were lowered into the cells only
when there was sufficiient air to operate the instrument.
