Selfrunning cold electricity circuit from Dr.Stiffler

[PaulLowrance]

Here is a short video using two rechargeable 9v batteries to run the exiter's to charge a big 12v battery.

The negative side of the run battery is going to the positive side of the cap.
Then the negative side of the cap is going to the negative on the exiter's.

Both exiter's the L3 coil is replaced with an AV plug that is also going to the cap.

Then the power from the cap is going through a diode to the charge battery.

After around an hour of running the charge battery went from 12.0v to 12.54v.

Looks interesting. If you can take the big battery voltage measurements after it has been resting unused for at  least several hours and still show an increase in voltage, then that's amazing. Let me know if that's possible, then I'd love to replicate it.

IOW, let big battery sit unconnected for at least several hours, measure it's voltage, then connect your circuit and charge the big battery, then disconnect big battery & let it sit unconnected for at least several hours, then measure it's voltage.

Also temperature makes a difference in battery voltage. If you can, write down the temperature. The adjustment is -0.022V/°C. So if the temperature changes, then use that equation to get the adjusted voltage so you can compare it to your 1st voltage measurement.

http://en.wikipedia.org/wiki/Car_battery
The open circuit voltage, is measured when the engine is off and no loads are connected. It can be approximately related to the charge of the battery by:
Open Circuit Voltage (12 V)     Open Circuit Voltage (6 V)     Approximate charge     Relative acid density
12.65 V     6.3 V     100%     1.265 g/cm3
12.45 V     6.2 V     75%     1.225 g/cm3
12.24 V     6.1 V     50%     1.190 g/cm3
12.06 V     6.0 V     25%     1.155 g/cm3
11.89 V     6.0 V     0%     1.120 g/cm3

Open circuit voltage is also affected by temperature, and the specific gravity of the electrolyte at full charge.

The following is common for a six-cell automotive lead-acid battery at room temperature:

    * Quiescent (open-circuit) voltage at full charge: 12.6 V
    * Unloading-end: 11.8 V
    * Charge with 13.2â€"14.4 V
    * Gassing voltage: 14.4 V
    * Continuous-preservation charge with max. 13.2 V
    * After full charge the terminal voltage will drop quickly to 13.2 V and then slowly to 12.6 V
    * Wait at least 12 hours after charging to measure open circuit voltage, the resting time allows surface charge to dissipate and enables a more accurate reading.
    * All voltages are at 20 °C, and must be adjusted -0.022V/°C for temperature changes.

Hello Paul.

I did let it sit all night and checked the voltage in the morning.

The voltage did drop a little in the charge battery.

It dropped from 12.55 to 12.32 after sitting all night.

I then drained the battery and recharged it.
This time I used a 12v in series with a 9v for the run batteries.

It charged so fast the charge battery went up 12.80 in no time.
The run battery was a 12v @ 12.24 the 9v was @ 9.01v

The 12v run battery went down to 12.20v then after sitting recovered all it's power back to 12.24v

The charge battery went down from 12.80 to 12.61 after sitting two hours.
But is now holding at 12.61

That's amazing. I mean, even 12.32V because it started at 12.0V, right? If someone was to replicate one of these circuits, can you point out the most efficient one, perhaps yours or one of Dr.Stiffler?

Thanks Paul.

The circuit I'm using is the Sec 15.It can be found on this page.

But I have two Sec's on the same board I'm using.
Here is a video of the two sec's I'm using.

For the charger circuit I removed the L3 coils and put an AV plug in it's place.
