🔋 Why the 12V Battery Is Crucial in Hybrids
Unlike petrol cars, hybrids rely on the 12V battery to power up the vehicle’s computers, relays, and high-voltage contactors. If the 12V battery fails, your hybrid can act completely dead, even with a full hybrid battery.
Your hybrid needs a healthy 12V battery to:
-
✅ Boot up the hybrid control system
-
✅ Engage the high-voltage relays
-
✅ Power ECUs, sensors, and BMS systems
-
✅ Run accessories, safety features, and lighting
