Charge Battery From Capasitor.

[Groundloop]

@zerotensor,

It depends on the voltage and current from the pulse motor. If the current is higher than the discharge rate
of the SCR into the battery then the current will never stop flowing and the circuit will not work. This problem
can be solved with a resistor (of some few Ohms) in series with the plus rail on the input of the circuit.

There are other solutions also. One can use a 555 timer to trigger a MOSFET transistor and dump the capacitor
into the battery.

Groundloop.

@slayer007,
Normally one solder a high Ohm
resistor over the capacitor leads to discharge the capacitor when not in use. In this case we do not!
The reason is that this waste energy and I guess that you are aiming for free energy.

A megaohm resistor connected across the terminals would not draw very much current, and any significant "free energy" being generated by the device should be able to overcome the the energy lost in the resistor.  Strictly following your logic, one shouldn't use any resistors (or wires, even), at all in the circuit!  But I hear you, Groundloop, and I can understand the impulse to get rid of this "unnecessary heater" in the circuit.  Whatever, as long as slayer007 understands the dangers... (You hearing me, slayer?)

Be safe.

Something else to consider, the pulse motor which charges the capacitor might need to be isolated from the battery charging circuit during the battery-charging part of the cycle.  If it is not, current might flutter in a secondary coil of the pulse motor as the capacitor rapidly discharges.  I like the idea of using MOSFETs and a 555.
