Top 3 Customer Questions & Concerns 🙋‍♂️

⚡ Can this tester tell me if my alternator is bad? Yes. While its primary focus is battery health, the V311B can also analyze the starting system and the charging status, which helps identify if the alternator is providing the correct voltage back to the battery.

🛡️ Is it safe to use on a battery that is still connected to the car? Yes, the V311B is designed to test batteries both in and out of the vehicle. The reverse protection design ensures that even if you accidentally swap the red and black clips, the device will remain safe.

🔌 Does this device require its own internal battery? The V311B typically draws power directly from the 12V battery it is testing. As soon as you connect the clips to a battery with a minimum charge, the screen will power on automatically.
