It might be cheaper to ship them from China than from the UK.
Apparently there's some kind of agreement in place that makes shipping
stuff from China (or Hong Kong) cheap --- but I don't know if it
applies to UPS batteries.

Maybe, maybe not.  I couldn't get replacement batteries for the UPS
from HP not only because HP was so ridiculous as to tell me that I
could pay for a support ticket to get a price for the batteries, but
also because the replacement batteries I could get had smaller
contacts.  Since I didn't want to take the risk of burning down the
place because the smaller contacts might have melted under load, I
decided to get a new UPS.

It wasn't too bad because I had only payed 65 for the UPS, and the
batteries lasted about 3 years.  I hate having to trash a perfectly
good UPS just because the batteries aren't available, and shame on HP
for being so environmentally friendly as to make and sell one-way
UPSs.  That kind of thing should be illegal.

But it was a lesson about battery availability.

Well, I need the UPSs monitored so the computer(s) can shutdown
properly.

Did they put the power lines into the ground water or something like

At least you have some cooling.  Basically nobody here has that,
though it's probably becoming more widespread because it gets warmer
all the time, and it's unbearable in the summer.  Electricity is
insanely expensive here and keeps getting more expensive all the time.

Hm, if the OEM batteries actually lasted 5 years and if what you say
is true, they must have been some awesome batteries.  That UPS takes
two batteries which are tightly packed, and they can get very warm.
