Q: What does the battery voltage and charging test feature do?

A: The battery voltage and charging test function allows you to check your vehicle's 12V battery health and verify that your alternator is charging the battery correctly while the engine is running. This helps you identify potential battery or charging system issues before they leave you stranded.
