Why do you want to put a resistor in this circuit?
Buy the cheap diode.
1N5404 3 amp barrel diode, Radio Shack part #276-1144
no not instead of the diode I mean instead of the light bulbs?

I really like that I can plug in however many lights I want for more power.
So far five old batteries are back working and I have done them all with three lights.
I have a couple small lawn tractor ones to do and I will try one bulb then try two if I need to.
I really LOVE this thing.
I see,
I have a dedicated space for mine so it is just a light left on in my engine shed.
I have a collection of antique flywheel engines in there.
I have brought back to life a HUGE diesel tractor battery that would make several of the batteries in my pickup.
That big battery was only showing 1 1/2 Volt. That is one very weak cell.
A week later it was right there at 13.4 Volts.
I let it set two weeks and it was still 13.4 Volts.
Then I put a little float level charger on it until I need it again.
Now I have a good size battery that will not even wiggle the needle with the meter set on 10 Volts.
That one is going to get the rejuvenator tomorrow.
I found this thread about a month ago and decided to try it on 2 batteries that were DOA
the 1st one 1 did I did up at the house using grid 120v ac
the 2nd one I did I used my solar panel set up at the barn (used my inverter)
I got the same results with both batteries showing about 85% as good as new batteries
So now it doesn't even cost me anything for the electric
this is great
