High-voltage battery care
12V support battery, state-of-charge habits, and HV safety notes.
Manual reference: Owner manual — EV / hybrid high-voltage section
The 12V auxiliary battery supports locks, ECUs, and contactors — test it separately from the traction pack. Never open HV enclosures; follow Chevrolet guidance on long-term storage charge level.
