I have around 106 cycles and 99% health on my 540wh from 2022 with 7000km. Will health quickly go down from now or what do you think is to be expected? I never over charge and battery/bike is stored in a warm place. I just ask because my engine starts to sound worn out but I can maybe get at new one for a good price. But I wonder if it is worth it If the battery will fail in the near future
