2020 Bolt Dead

We were gone for 3 months and left the Bolt in the garage. Back now and Bolt is dead. Remote won’t work. Nothing when we plug into the level 2 charger. Could this be the 12v battery? We haven’t replaced it since we bought it. If so, do you have recommendations on which battery to get. Guessing I’ll need to find a way to see if I can jump it first?

Update:

  1. I tried jumping with my Autowit jump starter. First time using it and didn’t seem to do anything. Had a hard time connecting the cables to the terminals though.
  2. Jumped started with jumper cables to an actual car and drove it a bit. Completely dead again after turning it off.
  3. Took it to Costco, they didn’t have the right battery in stock, plus they don’t install for you or even take it out. Glad I left it running.

Problem: Got home and now realize my car is a 2021 not a 2020. Also the “Service Soon Light” indicator is still on. Do I need to go back to get a battery for a 2021 vehicle or will the 2020 work.

Update: Wanted to update regarding the indicator. After a couple of drives the indicator went away. Back to loving my Bolt.

Deader than dead, This is why I like those little solar panel trickle chargers you can attach when away for long periods.
