      Philip MooreJul 26, 2025
      If your Schumacher Battery Charger isn't turning on, there are several potential causes: * **AC outlet issue:** Check the fuse or circuit breaker supplying the AC outlet. * **Poor electrical connection:** Inspect the power cord and any extension cords for loose plugs. * **Reversed connections:** Unplug the charger and reverse the clips. * **Low battery voltage:** The charger has an automatic start feature. If the battery voltage is under 0.2 volts, the charger will not detect it and will not start the charging process. * **Defective Battery:** Have the battery checked or replaced.

    Why is my Schumacher SP1 making a clicking sound?
    • M
      Melissa ClarkNov 18, 2025
      An audible clicking sound from your Schumacher Battery Charger can indicate a few issues: * **Defective Battery:** The battery may not accept a charge, especially if deeply discharged. Have the battery checked. Allow charging to continue, giving the battery time to recover. If clicking persists for over 20 minutes, discontinue charging and have the battery inspected. * **Severely discharged battery:** Have the battery checked. The battery may not want to accept a charge due to a run-down state. Allow charging to continue until battery has a chance to recover sufficiently to take a charge. If more than 20 minutes, stop charging and have the battery checked. * **Reverse Connections:** The connections at the battery may be reversed. Turn off the charger and correct the lead connections...
