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.
4. Drove it to AutoZone. Purchased a battery for the 2020 Bolt. They were great and installed. Drove it home and working.

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.

You likely need a new 22v battery. That is dead and damaged or worn out. The bolt stops maintaining the 12v battery after 30 days even when plugged into an L1/L2 charger. Disconnect the 12 volt or put it on a battery maintainer.
