it is caused by the good design of the server's power supply unit.

APC tells you to use theirs. But you can take the battery out and ask a
battery dealer if there is a replavement available.

This sounds like a perfect deal if the price is well below USD 200.

It will be possible in a private environment to use the battery of the
same type which is a bit smaller in size. The connectors seem to be
standard connectors.

Your URL shows the two battery types the UPS works with. Ask a search
engine if there are compatible batteries available. This is the case
for many APS models I know.
