In this post we learn how to recharge and use bad, defective discarded lead acid batteries using an innovative battery charging process invented by John Bedini.
Lead acid batteries can sometimes be a problem to get rid of. They can also be high priced to upgrade. In case discarded in the wrong way, they have a tendency to finish up in the land fill up or even rotting of in your junkyard.
Contribution of John Bedini
John Bedini has presented a bequest to the world which can bring back and enrich the used, abandoned, sulfated lead acid batteries.
In case a lead acid battery is sulfated from typical utilization, it may commonly be recovered using this discovery.
Batteries which have material impairment or have warped plates are worthless. The Bedini SSG (Simplified School Girl) generator can separate the sulfation on the battery plates and energize the batteries. On many occasions, the battery will in fact acquire further voltage, workable power compared to the time it had been purchased.
By means of routine utilization, a lead acid battery would probably gradually drop its potential to hold electricity. This can be witnessed by the necessity to charge the battery far sooner every time. Typical battery chargers often give rise to this consequence due to heating effect of the battery.
Because the plates get hot by way of charging, these are steadily weakened. A battery may have less electrical power every time it is utilized.
With the Bedini charger, that is not the situation. I have reconditioned batteries which were found resting around in a trash.
A couple of such batteries that possessed a charge of below 2 volts each presently are running my electric boat generator.
These types of batteries were not consuming a charge with regular chargers. After a while and many rounds with the Bedini charger, the batteries have become superior to brand new.
How Bedini SSG Function
This electric motor would not self start. You need to provide it with a little bit force to pick it up going, however once it begins rotating it is going to turn up by itself and self adjust its very own acceleration and speed depending on the dimensions and charge condition of the batteries getting charged.
Since a magnet moves down the coil, a tiny electric current is stimulated into the main coil.
This activates the transistor to switch on, enabling electricity from the operated battery to stream by way of the supplementary coil.
The magnetic field generated in the secondary coil provides the cycle a tiny lift up on its path past the coil.
As the magnetic field sets off the coil, the transistor is turned back off. This leads to the magnetic field in the supplementary coil to drop (back emf).
During this period, the vibrant electric power makes its way into the process which is emptied via a diode into the batteries to be charged.
This method could be demonstrated to generate additional energy on the recharging aspect compared to the need to steer the motor. In the method presented, the input current amounts between 150-200 mA.

Hi Sir,
Do you happen to have a battery swapper circuit which can be implemented in this Bedini circuit diagram. I have seen your "Twin or Split Battery Charger Circuit ' (https://homemade-circuits.com/2014/05/twin-or-split-battery-charger-circuit.html). Can this be integrated with the Bedini circuit diagram . If YES, what modification should be done on this circuit .The aim is to let the motor run without having to physically stop and swap the battery , making it almost overunity unit.
Many thanks in advanced.

Hi Naser,
both the batteries are differently rated so cannot be swapped….the primary battery is any used, discarded, sulphated low AH battery while the other one is a good battery….I don't think swapping the batteries is recommended in the design.
Swagatam says
….moreover the primary battery never gets discharged according to the theory

My battery a SLA 200 ah was over charged and swollen. Now as soon as i apply an initial charge the voltage immediately rockets up to 15 witìn 1minute, a particular cell overheats while other 5 cells remain cool as long as possible. The battery drops as soon as say two amps is applied. Is the cell open circuted. If not can your recovery circuit bring it back to a better state ?
Swagatam says
a swollen battery means it's almost beyond recovery conditions.

Hi sir.i have few questions.
1)can it recover a dead sla battery?
2)can i use PWM desulfating circuit weather it can also recover a dead sla battery?
3) once the battery is recovered weather it can be used to normal battery charger?
Swagatam says
I am not sure….the article was submitted by somebody else.

I cannot find motor in the circuit and how many turns i have to use for trigger coil ?
Swagatam says
the wheel with the magnets placed near to the coils acts like a motor when given a push.
The initial push induces a small current in the primary coil which is amplified by the transistor and the secondary coil network.
This amplified voltage creates a relatively strong magnetic field around the iron core of the coil. This magnetic field interacts with the wheel magnets providing another extended push to it….the cycle provides enough momentum to the wheel mechanism to keep it moving almost permanently.
The back emf generated from the coils is used for charging up the battery.
both the coils are 850 turns.

Is motor (wheel wid mgnt) is connected to coils? Can i eliminate small bulb given in the circuit?
Swagatam says
No…the wheel magnets move very close by the coil core while rotating.

Is there any electronic component that i can use in place of neon bulb?
Swagatam says
try a diac DB-3
