What tool is used to check battery voltage?

• A. A voltmeter
• B. A battery tester
• C. A multimeter
• D. A clamp meter

Answer: (C)

Checking battery voltage is about reading the electrical potential difference across the battery terminals. A multimeter is the tool of choice because it has a built-in voltmeter function for DC voltage and also lets you verify other electrical properties if needed. In practice you set the multimeter to DC volts, connect the red probe to the positive terminal and the black probe to the negative terminal, and read the value on the display. This one instrument is versatile enough for quick voltage checks and for future tests, such as resistance or continuity, without needing separate devices. A voltmeter would also read voltage, but a multimeter combines that capability with additional functions, making it more convenient in a shop setting. A battery tester focuses on how well the battery delivers current under load rather than just the static voltage, and a clamp meter measures current using a magnetic field rather than directly reading the battery’s voltage.
