What voltage should my battery show?
Here is how to read your 12V battery voltage on the Creader G700 at a glance:
🚗 Engine OFF (Resting Voltage)
12.6V – 12.8V: Fully Charged (Healthy);
12.2V – 12.5V: Partially Discharged (Needs charging soon);
Below 12.0V: Dead/Failing (Replace immediately).
⚡ Engine ON (Alternator Charging)
13.5V – 14.7V: Normal Charging (Alternator is healthy);
Outside this range: Under/Overcharging (Get your alternator checked);
💡 Quick Tip: For the most accurate resting voltage, test the car at least 30 minutes after driving. If the screen shows a normal voltage but your car still struggles to crank, it's time for a professional load test.
How do I check alternator health?
You can test your alternator’s charging system in real time using the LAUNCH G700. Follow this quick 3-step test:
Step 1: Get Connected Plug the scanner in, start your engine, and navigate to "Live Data." Look for the Battery/Control Module Voltage parameter.
Step 2: Check Idle Voltage Let the engine idle with all accessories off. A healthy alternator should read between 13.5V and 14.7V.
Step 3: Run a Load Test Turn on your headlights, A/C, and radio, then rev the engine to 2,000 RPM. A strong alternator will hold steady at 13.5V+.
⚠️ Failing Signs: If your voltage dips below 13.4V under load, stays flat, or spikes above 14.8V, your alternator is under/overcharging and needs immediate inspection to prevent ruining your battery.
