Foxwell NT301 Plus

Customer Problem: I already follow the user manual to use NT301 Plus to test my car battery. I have to clarify that this battery is a completely new one which was replaced by the vehicle repair shop a week ago. Since at that time, I didn't have an OBD2 scan tool. Otherwise, I would diagnose the problem and replace by myself. It cost me huge money. The battery's actual rating is 850 CCA, but this unit just kept giving me the wrong digital readout of "385 CCA". I couldn't figure out why this strange problem would happen to me. Hope to solve it as soon as possible.

Connect the red clamp to the positive (+) terminal and the black clamp to the negative (-) terminal.
