Fantastic I hooked up a halogen headlight bulb to the positive of my 12 v battery charger and it charged an old 6v tractor battery up no problem.
Thanks.

I Need to charge a 6 volt tractor battery with a 12 volt alternator. (Off Grid system). Do I just need to place a 12 volt bulb or 12 v appliance in the same circuit to do this? Thanks

Was it a step down circuit used if yes for how much output voltage ?

Basically you made a resistor divider circuit with the light bulb acting as a resistor.

So to charge a 7.5v battery... you used a 12v charger and a 12v halogen light bulb? I need to charge three 6v batteries. I just want to make sure I heard you correctly in the video.
