Second winter, if seller was honest, to basic cheap battery 6 AH. Works fine with no need to charge, driving one hour two times a month during wintertime.
Was two week heavy winter, got warmed few days ago, between -7 to -21 c.
Moved scooter to warm +15 c garage for 24 hours to warm. Then starting in max. 10 second periods, and after five? times, when carburator got filled enough, easy nice start from button, kick is broken somehow.
I was quite sure that battery will die before fires up, but luckily no. They sell new ones from 25 to 90 €, so the prices are affordable when needed.
