Why does the LED not light when my Schumacher Battery Charger is properly connected?
If the LED doesn't light when the charger is properly connected, it could be due to: * A dead AC outlet. Check the fuse or circuit breaker supplying the AC outlet. * A poor electrical connection. Inspect the power cord and any extension cords for loose plugs. * A defective battery. Have the battery checked.
What to do if the and LEDs are lit on my Schumacher Battery Charger?
If both the and LEDs are lit, it indicates that the battery is sulfated and the charger is in desulfation mode. Allow the charging process to continue for several hours. If the issue persists, have the battery checked.
What to do if the LED is lit on my Schumacher SC1339 Battery Charger?
If the LED is lit, it could indicate several issues: * The battery voltage is still below 10V after 2 hours of charging, which may mean the battery is defective. Ensure there are no loads on the battery; if present, remove them. If not, have the battery checked or replaced. * In maintain mode, the output current is more than 1.5A for 12 hours because desulfation was unsuccessful, which may mean the battery is defective. Have the battery checked or replaced. * Lack of progress is detected and battery voltage is below 14.2V, which may mean the battery is overheated. If so, allow the battery to cool. * The battery’s initial voltage is below 12.2V and the total input is less than 1.5 Ah. Have the battery checked or replaced. * The battery voltage drops to below 12.2V in Maintain Mod...
