We are under Stay at home guidelines for my NC county (Mecklenburg) for at least 3 weeks. I am putting a battery tender (or trickle charger) on my Onyx every few days to keep the charge up. I keep one on my mower and a 2002 Audi TT Roadster that I don’t drive all the time and it makes a huge difference in battery life. There is always a drain on a newer cars battery and this will keep it charged if not being used for a while. I am just swapping the one from the TT but they are not expensive. Any other ideas?
