🔋 Why the 12V Battery Is Crucial in Hybrids

Unlike petrol cars, Toyota hybrids don’t use the 12V battery to crank the engine. But that doesn’t mean it’s unimportant. The 12V battery powers all the vehicle’s ECUs, relays, and sensors that are necessary to boot up the hybrid system.

If it’s weak or flat, the entire car stays dead—even with a full hybrid battery.

🚨 Common Symptoms of 12V Battery Failure in Hybrids:

🚫 Car won’t turn on or “READY” light doesn’t appear
🔄 Repeated clicking or no response from the power button
⚠️ Multiple system warning lights
📉 Slow or intermittent infotainment system
🧊 Cold weather starts fail more often
