Schumacher SC1309 2/6/40/200A 6V/12V DOE Battery Charger and Maintainer

Q: Will this charge a completely dead battery?

Yes, the SC1309 will charge a completely dead battery, unless the battery is bad. If you are using the engine start feature, we recommend first using the boost mode to quickly add energy to the battery.

Q: Does this unit have internal batteries or is it powered by AC?

The SC1309 does not have an internal battery. It must be plugged into any AC outlet before charging will start.

Q: Will the SC1309 desulfate a battery?

Yes, the SC1309 has an automatic desulfation mode. If the battery requires desulfation, the unit will automatically switch to desulfation during charging. Desulfation can take up to 10 hours.

Q: Why did my charger turn off and then back on?

The charger detected that the battery may be getting too hot, known as thermal runaway. Allow the battery to cool. If it continues, have your battery checked. It may need to be replaced.

Q: Can this unit be used with an extension cord?

The use of an extension cord is not recommended. If you must use an extension cord, the pins on the extension cord plug should match the pins on the SC1309’s plug and the wire gauge must be large enough for the AC ampere rating of the charger.
