Car appreciation... the aesthetics, the engineering, etc

Yeah I did all this last time. I'll check the battery coz it now seems fucked.

I can't remember what the drain was but it's probably in this thread. The last time I was worried it was high drain but that was just the security system arming and stabilising. Measuring it after 10s the drain numbers didn't seem too high. But how long in this cold-ass country can batteries sit with even a little bit of drain? My old car had zero tech in it so probably had very little drain and it was in a country that stays in the postitives re: degC.
