Great work every step forward is progress I might have an idea on how to trigger your circuit more efficiently I'll build the circuit and post it asap also small trigger transformers may also aid you in stepping up your charging
The change in voltage going up and down is called surge leveling. You are surging the batteries and they charge unevenly then level out based on the impedance of each battery. This causes the batteries to charge and appear to discharge this as you have seen is only temporary. One thing I have noticed is the surge and the response from the battery. I have seen this effect by connecting a small load to the battery then watch the response of the battery after disconnecting the load.
My thought on the shunt diode across the relay coil was to eliminate the back emf from a possible power source. It also protects the signal generator.
I would like to see you to place a diode across the relay coil in reverse polarity to shunt the back emf. Also is not the outer shell of the electrolytic cap normally connected to the negative side of the cap?
No need to reuse the BEMF of the coil because the coil is fed by an frequency generator (FG) which I am paying for it. That FG is outside and isolated from the 2 batteries. Only the switching is necessary.
The outer case (in my case at least) is not the same as either the positive or negative of the capacitor. I am connecting it to the negative manually.
no at this time. I have to purchase a data logger for my meter so that I can have more accurate measurement. For now, baby steps. Let's see if work than I will improve on it.

I agree, having light forever is very nice. With the light you can do so many things.

Are your voltage measurements at regular intervals?
2hr interval? ....?
Good follow-through, my friend.
