  If the CHARGING light is blinking on your Schumacher Electric Battery Charger, it means the charger is in abort mode, possibly due to a faulty battery or because the battery didn't reach full charge within 48 hours. This can happen with very large batteries or battery banks that need more power than the charger can provide in that time. To fix this, unplug the charger to reset it, then select the CHARGE RATE and BATTERY TYPE again, if needed.

  If your Schumacher Electric Battery Charger won't turn on when properly connected, the AC outlet might be dead, or there could be a poor electrical connection. Check the fuse or circuit breaker for the AC outlet. Also, inspect the power cord and any extension cords for loose plugs.

Why Schumacher Electric Battery Charger can't reach full charged voltage?
- L
  Luis WrightSep 4, 2025
  If your Schumacher Electric Battery Charger fails to reach the 'full charged' voltage, it could be due to charging a large battery or battery bank on too low of a current setting, or the battery may have a shorted cell. Try again with a higher current setting or have the battery checked or replaced.

Why is the battery voltage still low after charging with my Schumacher Electric XC10?
- D
  David BlackSep 7, 2025
  If the battery voltage remains under 10V (for a 12V battery) or 5V (for a 6V battery) after 2 hours of charging with your Schumacher Electric Battery Charger, it may be caused by attempting to charge a 6 volt battery on the 12 volt setting, or the battery could be faulty. In this case, have it checked or replaced.
