  If your Matco Tools Portable Generator jump starter isn't jump-starting your car, several factors could be at play. First, ensure the clamps have a solid connection to both the battery and the frame, and that these connection points are clean. Next, verify the jump starter's battery charge by pressing the Display button. The display will show the percentage of charge. Finally, the vehicle's battery itself might be defective, so consider having it checked.

What does it mean if the red BAD BATTERY LED is lit on Matco Tools Portable Generator?
- R

  If the red BAD BATTERY LED is lit on your Matco Tools Portable Generator, it could indicate several issues. The battery might be sulfated, in which case the charger is in desulfation mode, so continue charging for several hours. If there's a lack of progress and the battery voltage is below 14.2V, or if the initial voltage is below 12.2V with low total input, have the battery checked. Also, ensure the battery cools if the voltage drops below 12.2V during Maintain Mode. The battery might be too large, have a short circuit, be too old, or have a low capacity, so have it checked or replaced. Finally, ensure there are no loads on the battery; if not, have it checked or replaced.

Also, in maintain mode, if the output current exceeds 1.5A for 12 hours, or if desulfation was unsuccessful, ensure there are no loads on the battery. If issues persist, have the battery checked or replaced.

  Denise EwingAug 31, 2025
  If the green POWER LED on your Matco Tools Portable Generator does not light when the charger is properly connected, the AC outlet may be dead. Check for an open fuse or circuit breaker supplying the AC outlet. Alternatively, there might be a poor electrical connection; inspect the power cord and any extension cords for a loose-fitting plug.
