Austine,

Yes, of course a battery’s energy can be used to charge another battery thru an isolated or non-isolated charging circuit. But some of what I’m reading below is bordering on being a perpetual motion machine and that violates scientific principles. It simply will not work.  Your system described below with the ac motor, car alternator, & car battery will work initially assuming the battery is initially charged. But the losses in the inverter, from the IR drops in the motor and alternator, & from friction will cause the battery to eventually discharge and go dead. You would then have to re-charge the battery from another energy source (like the 120 VAC utility power line or another battery). Once re-charged, you could then re-start the system again until the battery went dead from the losses.

So what’s the point? There is no free energy here. If you have the parts, you can build this relatively inexpensively and see for yourself. Many others have had the same basic idea, but always with the same results. There is no such thing as perpetual motion. A better way to get almost limitless, renewable energy is to use the sun, wind, waves, geothermal, and other similar energy sources that are all around us and can easily be converted into useful electricity.

What about if the other power source is a third battery on the same circuit?

Actually, with the two batteries that you described with a common point (one pos, one neg), that is a common point and a single, higher voltage charger can charge both batteries at the same time since they are in series. The open circuit charge voltage needs to be higher than the two battery voltages added together in this case. There's no need to use complex relay switching.

It doesn't matter if the other power source is a 3rd battery on the same circuit. This kind of cross charging can be done and it will work. What it won't do, however, is to make a perpetual motion or free energy or over unity situation. There are few situations that will even theoretically work that way. One is LENR (low energy nuclear reaction) and another is energy harvesting from existing mechanical, electrical, or thermal energy sources. Like using ocean wave energy to generate electricity or using geothermal energy or wind energy to turn a generator and make electricity. Another example is capturing electromagnetic energy (RF) in wireless form to generate electrical power and this is easily done, but not very practical unless one is near a high-power radio station or HV power line. This is not perpetual motion and it does not violate the laws of physics. It's simply a conversion of one form of energy to another, usually using some excess or easily available energy source. Unless the laws of physics change, nobody will ever take a separate motor and generator, and use the motor to turn the generator to charge the battery that powers the motor to get free, over unity energy. The best one can do in that situation, is to extend the time the motor will run till the battery goes dead for a given apparatus.  

Is there any way a battery can charge other battery through isolated Charging circuit powered by a battery?

yes its possible, with the right technique.

we don,t create energy we just convert it from one form to the other.

energy is all around us, we a literally swimming in it.

example, lets say you light a candle, as it burns, it gives off heat and light, this two forms of energy gets re absorbed into the environment, into the sea of energy that surrounds us. now why is it not possible to draw out any form of energy  we desire, in our own case, electricity.

Tesla demonstrated this with his infamous Tesla coil. so yea its possible.

however energy is not free, because you have to do some work to get it, you don't just sit down and it magically appears, that will be sorcery. but how efficient is your technique, most of our commercial energy converters or power generators are largely below 50% or less, whether by design or foolishness.... i will leave that debate for another forum.

Anyway getting back to the main subject, what your trying to achieve involves a technique that involves efficiency of over 300%. my own personal design,i call it power kinetics, Its an improved version of a Tesla switch.

the concept is simple just as water flows through a channel or turbine, spins it and gives off mechanical energy. the same applies to forcing electric current to do work while flowing to a load point, irrespective of DC or AC.

i will be back later with more info

Take 2 Glasses and fill them with water (these are your charged batteries)

Drink some of the water from one glass (this is your load)

Fill that glass with the water from the full glass (this is your first recharge cycle)

Drink some water from that second glass.

How far can you get before you run out of water? Exactly two glasses of water = two full battery charges.

Hello my name is Conroy and i am from Jamaica.. What if a inverter is being connected to a battery source to give out a AC energy of 120volts and you use back that 120AC energy to power a battery charger to charge back that same battery that needs to keep charge to keep the inverter going. Is that possible?

It's perfectly possible, but quite useless.

All the energy from the battery will be lost warming up the inverter and the battery. When you charge a battery you always need to put more energy in than you took out to get it back to the original state. ALL inverters are less than 100% efficient.

There is no way to get energy for 'free' no matter how cleverly you connect up batteries or magnets.

Think about this:

To charge a 12V battery at 10A you need 120W.  If your inverter was 100% efficient, and all your wires had no resistance, you would need 120W back from the battery (10A).

If your inverter is only 95% efficient, you would need 126W (10.5A).  So You are drawing 10.5A from the battery and only charging with 10A, your battery will soon be dead.

It gets more complicated when you take battery resistance into account.  You can't just charge the battery at 12V, you need 14V or 15V to get current flowing into the battery.

At 15V @ 10A, you are using 150W, so it would draw 12.5A from the battery charger at 12V, your battery is dying even faster.  Inside the inverter there are losses in the transformer, losses in the diodes and transistor junctions, and all the connecting wires have resistance, causing energy loss as heat.
