My car battery is deeply discharged and I need to convince my RING RSC808 smart charger to do the job because the battery cannot convince the charger to start charging at 0.0 volts. The dead battery is out of the car as there is nowhere to charge from in the underground car park. I am thinking I need a charged battery wired in parallel to convince the charger to work. I am going to see if my local garage have a charger that can work from 0.0 volts (plan B). But, am I on the right track? I don't have a spare 12v battery lying around. These smart chargers leave a lot to be desired.
