More About the Schumacher SC1309

Specifications: The Schumacher SC1309 is a fully automatic battery charger that works with both 6V and 12V batteries. It has a strong 200 amp engine start to get your vehicle going fast, a 40 amp boost to wake up weak batteries, and a 6/2A charge/maintain setting for keeping batteries healthy. It weighs 30.1 pounds and measures 11.25″D x 9.75″W x 33.38″H. The input voltage is 120 volts, and the output is 12 volts (DC). It’s made tough with a machined exterior and comes from Mexico.

Benefits: This charger is super easy to use and keeps your battery in top shape. The built-in tester checks your battery and alternator, so you know if something’s wrong before it’s too late. It’s portable with wheels and a handle, so you can move it around without a hassle. Plus, it’s energy-efficient and safe, meeting high standards like Schu Eco Energy and DOE compliance.

Usage Instructions: Plug the charger into a 120-volt outlet. Connect the clamps to your battery—red to positive (+), black to negative (-). Pick your mode (engine start, boost, or charge) using the buttons and watch the digital display. It’ll adjust itself to keep things safe and simple. When done, unplug it and store it neatly with the retractable handle.

Care Guidelines: Keep the charger dry and away from water. Wipe it with a soft cloth if it gets dirty—don’t use harsh chemicals. Store it in a cool, dry place when not in use, and don’t drop it, since it’s built tough but not invincible. Check the clamps and cords regularly to make sure they’re in good shape for next time.
