Why is my Schumacher Electric SC-600A Battery Charger making a clicking sound?
- A
  Ashley RamirezJul 30, 2025
  If your Schumacher Electric Battery Charger makes an audible clicking sound, this could be due to several reasons. The circuit breaker might be cycling because the settings are wrong, so check them. The battery may be defective, so have it checked. There might be shorted battery cables or clamps, which you should inspect and replace if necessary. A severely discharged battery may also cause this, so allow charging to continue until it recovers, but stop after 20 minutes if it persists and have the battery checked. Finally, reverse connections at the battery can cause this, so shut off the charger and correct the lead connections.

  If the CONNECTED (red) or CHECK (red) light is not on, it could be due to a few reasons: the battery is not connected correctly, the connection to the battery is reversed, or the battery voltage is less than one volt. Check for poor connection to the battery and frame, ensuring the connection points are clean. Rock the clips back and forth for a better connection. Correct the connection if it's reversed. If the voltage is too low, replace the battery or try using a manual charger to bring it above one volt.

  If your Schumacher Electric Battery Charger will not turn on when properly connected, the AC outlet may be dead, or there may be a poor electrical connection. Check for an open fuse or circuit breaker supplying the AC outlet. Also, check the power cord and extension cord for a loose-fitting plug.

Why is the connected red light blinking on my Schumacher Electric SC-600A?

  If the CONNECTED (red) light on your Schumacher Electric Battery Charger is blinking, the charger may be in abort mode, or the battery may be faulty. This can happen if the battery doesn't reach full charge within 48 hours, possibly due to a very large battery or a bank of batteries requiring more power than the charger can deliver in that time. To resolve this, reset the charger by unplugging it. Then, select the desired CHARGE RATE and battery type again, if necessary.

What to do if charged green light turns on too fast on Schumacher Electric Battery Charger?
- Z

  If the CHARGED (green) light turns on too quickly after connecting the battery to your Schumacher Electric Battery Charger, the battery may already be fully charged or recently charged. Alternatively, the battery may be faulty (sulfated). If the battery is in a vehicle, turn the headlights on for a few minutes to reduce the battery voltage and try charging again. Also, try a lower CHARGE RATE selection. A sulfated battery will eventually accept a charge if you continue charging for a few hours. The CHARGING (yellow) LED will blink. If not, have the battery checked or call customer service.
