I write directly from the wheels! Bought yesterday 02/16/21. After the frost, the battery failed (7 years in operation). The car sat for 3 days. I tried to spin - not the slightest sign of life, the battery was discharged to zero. Today 17.022022, air temperature -10°C, car Nissan X-trail T31 2 liters. Wound up with half a poke. I recommend!
I added some photos to give others a better understanding of my experience.
