New start – stop battery at V60 2011 original or alternative?

Hello together, I have my v60 for 2 years. He is now 7 years old and still has the first battery in it. However, she will soon give up her mind, have often display “low battery charge” and the Start Stop function works almost never, which however does not bother me. I asked the friendly because of battery and the original is at 257 Euro!! A little violent. I looked around and for example the silverhttps://www.idealo.de/…/…ilver-dynamic-agm-1 2v-95ah-g14-varta.html varta. What do you think about it? What do you have installed and what does it fit? My data : V60 2.4 D5 circuit In my battery compartment is even more space than for the battery that is now installed. I know that the height is important for it to fit in. Would be happy about your opinion and tips.
