Two weeks ago, I got myself a bolt 2019 with a brand new battery (2022). I still don't have my 220v charging station at home. So I'm using my 110v. I do 110km daily and mostly charge in 110v at work + home. Every 4 days i need to charge in 220 due to 110v not charging the battery enough.
Now since yesterday, my battery life says it caps at 114 miles, down from 242 miles (from 2 weeks ago).
Now I'm really getting pushy for an electrician to install my 220v charging station at home. But I'm wondering, did the battery permenently degraded from that? I saw in the recommendation to charge using 220v every week, which I did.
To give some context, I also live in a cold area of Canada where it's often around -5F.
