Batterie replacement on Disco II

Hi,
i am the proud owner of a Disco II 2.5 TDI, build 2000, and now my
batterie needs to be replaced. The original Delphi is very expensive in
Austria, and as a alternative replacement i am looking for the Varta #
610 048 068 3100, which seems to be right replacement ( regarding to the
Varta website - 12V 110 Ah ). But after some measurements i am still not
sure if this one will fit right into my Disco.

Is it worth to replace the Delphi with the varta ? Any experiences with
this Batterie ?

Thank you in advance for any help or hints.

Kind Regards
Reinhard

PS : Excuse my english, but i am from Austria and so my mother language
is german

Any battery will do as long as it has the same CCA rating as your old one.
