While there are several market devices and OBD tools available to check battery voltage, most of them are expensive and may end up lying unused. The good news? You don’t need any extra hardware or apps to view your car’s battery voltage your Car Android Stereo already has this feature built-in. You just need to activate it.

Let’s walk you through the step-by-step process to enable battery voltage display on your Car Android Head Unit.

Before jumping into the steps, here’s why enabling this feature is useful:

• Real-time monitoring of your car battery.
• No need for an external voltmeter or OBD scanner.
• Helps you detect battery issues early (low voltage, alternator problems, etc.).
• Especially useful for older cars or long-term parked vehicles.
