The Bolt EV has a AGM battery not lead acid.It's becoming apparent from posts on this forum and others that the 12V battery is somewhat of an Achilles heel for the Bolt. I know that lead-acid batteries have a finite life, and it seems that when they give up the ghost on Bolts they can create a variety of problems.
My question: What's the best way to monitor the battery status besides waiting for a problem to occur (which of course, will be at an inconvenient time). A routine check with a multimeter? I know that the Bolt system tries to keep the battery charged, so a good reading may be inaccurate on a weak battery. I could "load test" the battery, but would probably have to disconnect it to do that. Your informed opinion would be appreciated.
