OverUnity Lead Acid Battery Circuit - Achieves Infinite COP & Self Battery Recharging


The Purpose of the Switching Circuit

01.) To allow energy from the vaccum to enter the circuit & power the load.
02.) To achieve a very high degree of overunity by opening & closing the circuit continuously.
03.) To encourage self battery recharging by carefully matching the load to the batteries amp capacity.
04.) To identify when the best time to charge the battery is & how it should be achieved.
05.) To switch the battery in & out of the circuit in a controlled way & at a specific frequency. (Less Than 15 Hz)
06.) To prevent the battery from being permanently connected to the load.
07.) To prevent the source dipole from being killed.
08.) To maximise the efficiency of all overunity motors & circuits.
09.) To create a super battery which lasts 10 times longer & doesn't discharge itself.
10.) To provide a better way to power circuits when using batteries.


Overunity can only be achieved if you carefully match the battery capacity to the load it will power

If you attempt to draw excessive amounts of current from a battery, you can forget about overunity.

If you place too big a load on a battery, you will begin to kill to source.

No amount of feedback pulses from a motor / generator will change the situation.

If you place too large a load on the battery, you will be preventing the battery from recharging itself.

It is better to draw a small current for a long time & allow the battery to recharge itself when it is taken off the load.


I encourage everyone to do your own experiments, to determine what loads can be powered by a specific battery capacity.

The only way to know how fast a particular battery can recharge itself is to put it under load, vary the switching frequencies, on / off times, & then plot the results.
If you start at 20% of the Batteries Amp Capacity for these experiments - you can either increase or decrease the load.

The bigger the load, the greater the chance of the battery discharging.
Ideally you will need to do several long term tests to determine where the peak of overunity occurs & when it starts to drop.

The rated capacity of a battery is only for a closed circuit. If you are using a circuit which allows energy from the vaccum to power your circuit,
you are likely achieve excessive amounts of overunity. The amount of overunity you achieve depends on the load you will be powering.

In general if you draw less than 20% as an average, you should have a lot of success with self battery recharging.
When you get down to 10% you may be able to achieve infinite COP.

Charging Your Batteries With a Large 100 Amp / Hour Battery

When you charge a battery it must be done using a pulse charger, similar to a bedini circuit.

Charging should be done after the battery has been allowed to self charge itself.

You should only need to give the battery a top up, not a lengthy charge.

You don't need to build a bedini motor to do this.

You can make one of these pulse chargers using a 555 astable circuit with an adjustable pulse width, a (n type) mosfet & an iron dust or ferrite toroid.

If using an iron dust toroid T50-2, the frequency should be 30Khz & the number of turns = 45, using 0.6mm enammelled copper wire.

If using a ferrite toroid, the frequency should be about 5Khz & the number of turns = 8, using 1mm enammelled copper wire.

A single schottky diode can direct the back EMF spike to charge your battery, or you can use a secondary coil & a bridge rectifier.

A circuit drawing 0.5 Amps at 12 Volts will charge a battery slowly, so increasing the power used to 2 amps or more is something you should be looking at if you want a fast charger.

You should get hold of another battery to do your charging. (100 Amp Capacity is Ideal) as this will only use 2% of the capacity.

When you have got your 100 amp battery, place the switching circuit before the pulse charger & begin extracting free energy from the vaccum & charge
your smaller batteries for free. The 100 amp battery will quite happily recharge itself after 1 hour of being taken off load, because you made sure
it was being used in overunity mode & you didn't keep the circuit closed, unlike every other circuit out there.

A battery is charged when its voltage reaches 15 volts.

Its normal voltage is between 12.7 & 13.5 Volts depending on the battery.

Now that you know the secret of obtaining free energy from Lead Acid Batteries, you can tell all of your mates.

Here is a quote from Tom Beadens Website

In this scheme, we drive an ordinary d.c. series motor by a two wire system from an ordinary battery.
The motor produces shaft horsepower, at -- say -- some 30 or 40 percent efficiency, compared to the power drained from the battery.
This much of the circuit is perfectly ordinary.

The trick here is to get the battery to recharge itself, without furnishing normal power to it, or expending work from the external circuit
in the process. To do this, recall that a charged particle in a "hooking" del-phi river moves itself.  This is true for an ion, as well as for an
electron. We need only make the del-phi in correct fashion and synchronize it;  specifically, we must not release the hose nozzles we utilize to
produce our del-phi river or waves. The inventors who have discovered this have used numberous variations, but here we show a common one.

Thank you for your information.
I was planning to do a similar circuit in the next few weeks.  Now the task will be much easier.
God Bless.

OverUnity Lead Acid Battery Circuit - Achieves Infinite COP & Self Battery Recharging

This is the drive circuit for testing either a P-Type Mosfet or a Normally Open Relay.

The start button / switch is used to charge the super capacitor via a low value resistor & provide power to the 555 circuit.
The 555 needs at least 3 volts before it will begin to self oscillate. Once the 555 circuit starts to oscillate, the power switching will take over & will continue to charge
the supercap until it is fully charged. The relay placed across the low value resistor is used as a current regulator or short circuit protection circuit. Its cheap & effective.
You may also want to add a low value resistor to the output of the supercap since they can be quite dangerous if accidently shorted out.

The relay is a bit noisy, so the P-Type Mosfet really is essentially.
There is a pulse width adjustment using the two diodes in the 555 astable circuit & a variable resistor.
You can play around with the timing here.
The capacitor is approx 10 micro farads, this is what determines the basic frequency, the other two resistor set the on / off time or pulse width.

The circuit will operate up to 48 volts provided the 555 has a regulated 12 volt supply, so this could power a 48 volt mains inverter.
The N - Type mosfet part of the circuit is used to drive a big relay if you want to use one.
You can test the performance of various loads with a relay if you don't have a P-Type Mosfet at hand.

The switching part of the circuit can be constructed using a N-Type Mosfet but it makes life much harder, so just get the right parts if you are going to try this. Also I could not find a direct pinout for the P-Type mosfet IRF5305. The data sheets forgot to tell us what the pins were.

There is a missing wire on the pulse charger diagram, pin 8 on the 555 is +12 Volts, its not a mistake, I just haven't put it in.

If you intend to build these circuits, make sure that you use the exact component values that are shown.

There is a lot of oscillation with the pulse generator when you look at it on the oscilloscope. It does not affect the driving mosfet, but tends
to affect the mains powersupply. Use a 12 volt battery to power this circuit, ideally with the overunity switcher placed before it.
You can also use a secondary coil on the pulse generator to isolate the two batteries.
A 1 to 1 ratio is good & then feed it into a full wave schottky rectifier to charge the battery.
A few drops of superglue on the coil keep it from coming apart.

The iron dust toroid T50-2 works well at that frequency 33khz,  I can't recommend ferrite for this circuit.
Again use the exact component not one twice the size.

- -

I use schottky diodes for the flyback circuits, signal diodes for the 555 timer circuit.

The N-Type Mosfet is a HUF75337G3 - -
The P-Type Mosfet is a IRF5305 - -

At the present time I have tested the above circuits for functionality, I still need to design & make a small PCB so I can really test it out.
If the circuit provides a good deal of overunity, it should be possible to charge very large batteries using a small one, thats the goal.

Thank you for the circuit

I have a question about the capacitor. What is the voltage required for the capacitor?

I have some capacitor of about 10V at 100000 UF, this is to big? can I put 2 in serie to make a 20V?

Thank you!

8th March 2012

Here are two improved circuits which have been proven to function correctly off 12 volts.

The previous two diagrams I uploaded should be ignored since there are special requirements to switch the P-Type mosfet correctly.

The circuit performs well running a motor, or powering a resistive load, with or without a super capacitor on the output.

I tested a load of 18 ohms at 12 volts with a 6 farad car audio capacitor to keep the ripple to a minimum.
The current being drawn was 0.6 Amps.

The ripple itself was very small on the scope, the pulse width was 50% & the switching frequency was between 1 to 5 Hz.
The capacitor size does make a big difference.

The switching mosfet remained cold throughout & did not get hot at all, so this means it is being swiched on & off correctly.

As far as overunity is concerned this is a tricky subject. I do believe the switching circuit has improved the batteries ablilty to supply power
for longer, however, I have also concluded that some method of recharging the battery is needed. Usually you will just see the battery voltage fall
when you connect a load to it, but this switching circuit prevented that from happening for the most part.

The battery voltage did eventually begin to fall when a 0.6 Amp load was connected for more than an hour, across the super capacitor.

I have noticed that a battery can recharge itself to some extend, particularly when it is fully charged.
This usually occurs when you are applying brief loads & not using the battery for long experiements.

The circuit does its best to prevent the battery from being continuously connected to the circuit.
If there are any overunity gains to be had in the discharge cycle then you are going to get them.

I will be doing some more tests using (one battery to power the pulse charger circuit & charge a slightly discharged battery.)
There will be a number of different tests to determine whether using high current pulses can speed up charging.

I never saw anyone stack up a load of batteries & charge them all in series.
Do you get more charging from doing this or not.
If the pulse is going through a number of batteries, are they all being charged?
Overunity must come from the recharging cycle rather than the discharge cycle.

If John Bedini managed to get his motors to run continously without external power sources, there must be a trick to doing this.
I don't believe the magnets had anything to do with the charging of the battery, but I could be wrong.


Focus on the charging aspect to achieve overunity as this seems to be more productive.

There are a number of circuits to try out, switched capacitor charging & the tesla switch.

Two capacitors are charged with 12 volts, then placed in series & a load is powered while the battery is charged.
Two batteries charge one battery & power the load. The 3 battery are cycled around in one direction.

There are a number of ways of powering a load while charging a battery, but the charging is done using current, not a voltage spike.
All these circuits need to be tested completely so large supercaps are needed for these experiments. 6 Farads for 0.5 Amp Load.


Any Volt Micro - This is a mini switching regulator which steps up 4 volts to 15 volts.

This is what I am powering the 555 timer & the mosfet gate switching with a 12 volt battery.

The N-Type Mosfet is a HUF75337G3 - -
The P-Type Mosfet is a IRF5305 - -

The NPN Transistor is BC546 for 48 Volt Operation -

Improved circuit with gate drive protection & seperate any volt switching regulator to provide +3 volts above the source voltage. The circuit can be used up to 48 volts dc if the capacitors are changed & a seperate regulator can supply the 555 with 15 volts.

I am using a 6 farad car audio capacitor across the load, which has its own LED volt meter.

Question:  I have heard that these circuits quickly wear out lead acid batteries.  I think this happened to Bill Boyce's SA friend (Wyty... something).
I do know that powerful pulses can knock off chunks of lead sulphate.  Any ideas about this?

Hi All,

Please re-define the title correctly To Lead-ACID battery DESULFATOR .It's misleading.Please don't be offended.

I have already build a battery desulator base on PIC12F629 using 8 pin micro-processor could recover even 0.9v maintenance free Lead-acid battery(2Ah) to 12volts in 2days.

Even some of circuit people build tend to use a "lead-acid battery" when they noticed a rise in battery voltage ,the creator of circuit thought they have have created OU device.

They didn't know they have merely created a good battery desulfator device.

A real OU device should be running on ultra-caps or nimh battery where the internal self-discharge rate is higher.If there is voltage increase in cap or nimh then it could be the real deal without using any input batteries.

The switching cycle is 55us on with 1s off in infinte loop for programming the PIC12F629.This is just a replica of 555 base found in instructables site.I did micro-processor version merely to lower component count.

Please look at this link where i posted full finding around 2 years ago and even mentioned the 2 ways to check a 12volt battery(If the internal resistance is being lowered) while it's being desulfated or after desulfated.

HI, magpwr i have see your circuits and some explanation about your circuits you have built and tested as so far in the low current and the standard voltage , i have some question on it about this ,and i need your advice on this questions.

1. the circuits you build is low current and the L1 ,value of inductor its 1mH ,and the L2 ,220uH ,if this two component is i change to any other value for charging the battery of 60aH/24VDC battery bank means ,how to i design this coil for reach that current to have charge in the 6.or 8 hours duration charging time ,can you give some advice on this,please.

2. my system battery bank is 24v/60ah and my planing is to drive the lamp,dvd,computer,and etc, atleast for the 4 hrs time, and i want to connect with 1000watt inverter system for drive this load after the full charge the battery bank of i mentioned.

please advice for my design and for testing in my home projects  .

thank you

Hi Segar,

I have not tested on 24volt battery but i believe the only component you need to amend from my circuit is

R1=1K OR 1.2Kohms

IRFZ44V needs to be changed(Currently 60v but spike is around 44v for 12volts on bad batteries).
You merely need to get mosfet which could support at least 120v or 150v.
If you purely using it for maintenance of existing good batteries then mosfet could be 100v.

Please leave fuse at 500mA.

I have used car battery with ups(not using internal ups battery) on my pc\monitor.It works.
I'm unable to advise further.sorry.

The overunity quacks like bedini and bearden have done more harm to the name of Tesla than anyone else.
