Not in my experience, I would be seriously pissed off if I had to replace the batteries in my cars every two years.
Perhaps extremes of weather (Finland) might affect your battery… ???
Just wondering… as I would have said 2 years was rather short…
Jaguar XFR-S, tuned 590bhp supercharged 5.0 V8 and maybe not very economical
It has a nice sound to it

Stella its most probably both extremes the raw cold in Finland and the extreme heat in the Med, especially the last two years.
Aircon, engine heater, short runs takes it’s toll on any battery .
