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

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

for many APS models I know.
