The Battery widget will display your vehicle’s current battery voltage. This is a great tool for monitoring the health of your vehicle’s battery. If your battery’s voltage drops below 11.7v, a “Low Battery” badge will appear.
Note: receiving a “Low Battery” alert doesn’t necessarily mean you have to immediately replace your battery. Instead, try driving for at least 15-20 minutes at freeway speeds to recharge your battery. If you continue to see the “Low Battery” alert, consult with an automotive specialist to test the health of your vehicle’s battery.
