  • Charging slows down as the battery fills up.
  • GM recommends charging the high voltage battery to 80% or less unless the drive requires a full charge, and avoiding letting it fall below 20%.
  • At a DC charge station the station's cable must be less than 10 m (33 ft) long to meet functionality and regulatory requirements.
