What to do if the BAD BATTERY LED is lit on my Schumacher SC1279 Battery Charger?
- RRyan AndersonJul 29, 2025
If the BAD BATTERY LED is lit, it could mean several things. The battery voltage may still be below 10V after 2 hours of charging, or in maintain mode, the output current is more than 1.5A for 12 hours, desulfation was unsuccessful, lack of progress is detected and battery voltage is below 14.2V, the battery’s initial voltage is below 12.2V and the total input is less than 1.5 Ah, or the battery voltage drops to below 12.2V in Maintain Mode. Ensure there are no loads on the battery; if there are, remove them. If not, have the battery checked or replaced. Also, the battery may be overheated, too large, have a short circuit, have too low capacity, be too old, or won’t hold a charge. In such cases, allow the battery to cool or have it checked or replaced.
