What to do if my Schumacher Electric BE01251 has a short start cycle?
- A
  Amber PetersonJul 25, 2025
  If you experience a short or no start cycle when cranking the engine with your Schumacher Electric Battery Charger, several factors could be the cause. You might be drawing more current than the Engine Start Rate, in which case the crank time may be less than 3 seconds. Ensure you wait 3 minutes between cranks to allow the battery and charger to cool down. Check for poor connections at the battery and frame, and ensure the power cord and any extension cords are securely plugged in. Also, verify that the AC outlet has power and that the charger vents are not blocked. For a severely discharged battery, use the Boost setting for a few minutes before cranking.

Why is the Bad Battery LED on my Schumacher Electric BE01251 Battery Charger lit?
- H
  hbauerJul 31, 2025
  The Bad Battery LED on your Schumacher Electric Battery Charger may be lit because the battery voltage is still below 10V after 2 hours of charging, or, in maintain mode, the output current is more than 1.5A for 12 hours, or desulfation was unsuccessful or the battery voltage drops to below 12.2V in Maintain Mode. To resolve this, first, make sure there are no loads on the battery. If there are none, have the battery checked or replaced, as it may be defective.

What to do if the Bad Battery and % LEDs are lit on my Schumacher Electric BE01251 Battery Charger?

  Elizabeth HernandezAug 6, 2025
  If both the Bad Battery and % LEDs are lit on your Schumacher Electric Battery Charger, it means the charger is in desulfation mode because the battery is sulfated. Continue charging for several hours to allow the desulfation process to complete. If this is not successful, have the battery checked by a professional.
