What to do if Schumacher SE-1-12S Battery Charger is connected but not charging?
- C
  Colin MartinAug 14, 2025
  If your Schumacher Battery Charger is on but not charging, first, check for poor connections to the battery and frame, ensuring the connection points are clean. If that's not the cause, unplug the charger and reverse the battery connections. The issue might be a defective battery that won't accept a charge, so have it checked. Also, the battery must measure at least 1 volt to start charging. If it's under 1 volt, use a separate charger to bring it up to at least 1 volt before using this charger.

Why is my Schumacher SE-1-12S clicking?
- J
  janebaldwinAug 27, 2025
  An audible clicking sound from your Schumacher Battery Charger usually indicates a defective battery, shorted battery cables or ring terminals, a severely discharged battery, or reverse connections at the battery. To resolve this, have the battery checked. If the current draw is too high, the circuit breaker cycles. Inspect for shorted cables or ring terminals and replace them if necessary. If the battery is severely discharged, allow charging to continue until it recovers sufficiently. If it doesn't recover after 20 minutes, stop charging and have the battery checked. Also, ensure the lead connections are correct by shutting off the charger and correcting them.

Why is my Schumacher SE-1-12S making a clicking sound?
- A
  Aaron DavenportAug 31, 2025
  An audible clicking sound from your Schumacher Battery Charger can indicate several issues: a defective battery, shorted battery cables or ring terminals, a severely discharged but otherwise good battery, or reversed connections. Have the battery checked. The circuit breaker cycles when the current draw is too high. Check for shorted cables or ring terminals and replace them if necessary. If the battery is severely discharged, allow charging to continue until the battery recovers sufficiently. If charging continues for more than 20 minutes without improvement, discontinue and have the battery checked. Correct any reversed lead connections.

Why does my Schumacher SE-1-12S make a loud buzzing or humming noise?
- E
  Eric Short DVMSep 3, 2025
  A loud buzz or hum from your Schumacher Battery Charger is usually normal. The buzz is caused by transformer laminations vibrating. The hum may indicate a shorted Diode Assembly or Output Rectifier Assembly. If you suspect a shorted assembly, have the charger checked by a qualified technician.
