Now sure how much we can rely on this, it was an AI generated explanation. I don't know where it found its data.
Green:
Indicates a healthy battery and a sufficient state of charge, or that the battery is actively charging or discharging.
Orange:
Suggests that the battery is not charging, there might be a charging system issue, or the battery is low. It's also been reported that the orange indicator can appear when the 12V battery is being topped up by the DC-DC converter.
Red:
Indicates a serious problem with the battery or the charging system, such as a critically low battery level or a fault.
