Put on your safety glasses and gloves when working with lead-acid batteries as they generate harmful gases. Avoid contact with battery acid. It is also best to remove your rings, bracelets, watches, and necklaces while doing this.
This charger can be used for standard, AGM, deep-cycle, and lithium-ion battery types. Check if it is compatible with your car battery.
You can remove the battery from your car or it can stay in the engine compartment if you have a covered garage. Make sure your engine is off.
First, make sure all switches are in the Off position, then connect the Schumacher battery maintainer to the battery using the clamps. Connect the red clamp to the positive battery post and the black clamp to a free cable end.
Plug the car battery charger and maintainer into a power source. The outlet should be properly installed and wired. There should be enough space between the battery and the charger.
On the control panel, choose the particular battery type and size that you're using. The light on the control panel will turn green when the battery is fully charged.
Once the battery is fully charged, the charger will now go into maintaining mode or float mode so that it won't lose charge while in storage.
When it is time to disconnect the Schumacher car battery charger and maintainer, unplug it from the power outlet. Remove the black/negative clamp first before the red/positive clamp.
