Yep, it tests a 12V battery and can help determine how much energy is being supplied by your alternator. The best part of this device is that no internal batteries are required. Nice. The instructions were not very good, which is why I deducted one star. One example of the poorly written instructions is the LED read-out on the front panel. If you have a good battery, all three LEDs illuminate, and can be confusing. I would expect a good battery to light the "Good" LED, not all three. It is still a good purchase for some basic car troubleshooting.
