One of the neat things about GL's charger is the nature of its output. By substituting in a potentiometer for one of the resistors (can't remember now - not much time to look on my lunch), I was able to increase the output spike amplitude through at least 2 levels of harmonics that I could observe on my scope.

By hooking the leads up to a transformer, I was able to adjust the resistance until the transformer would hit resonance.

I believe GL's charger is harnessing radiant energy through the inductive kickback produced by its sharp transient voltage spikes.  Another interesting thing occured with small DC motors. When hooked up to the output of the charger, they would spin in either cw or ccw direction, depending, I suppose on how the brushes and commutator segments were aligned.  However, I took the shaft of the motor and spun it one way while hooked up the the GL charger, it would run that way, and conversely, if spun in the opposite direction, it would start to run that way as well.

In my view, this is more than just a charger. While not necessarily an OU device, it produces some interesting effects.

Sorry about my english.
I have made desulfator according to your post from January 09,2012, with some modifications and it is not working. Instead MJE15003 I used 2N3055 and instead LT7250 four UF5408 connected in parallel.
When I connect battery and power supply desulfator buzz, transistors are warm but battery voltage is anchanged. There is no output current. When I connect battery to a standard charger voltage rise.
Any suggestions?

Hi zeljkoc,

I do not recommend using the 2N3055 transistor in this circuit. The transistor is slow and does not tolerate
high voltage spikes from the coils. See if you can find any NPN power transistor that can take a higher voltage.
Also always use a heat sink on the transistor. I recommend using one NTE2354 on a heat sink.

Do you have a o-scope? Put a 12 Volt bulb (5-12 Watt) at the output as a load and o-scope to see if the oscillator
is actually running. Try swapping the L1 coil around to get a running oscillator.

Never run this circuit without a load. Always connect load first and then the input power. Have you checked that
your 2N3055 transistors are OK? One can be faulty stopping the oscillator. (If you are using two in parallel.)

The UF5408 diodes you are using is OK to use in this circuit. The UF5408 is rated 3 Ampere so it should be
enough to use one of them at the output.

What is the size (Ampere/Hour) of the battery you are trying to charge?

GL.

This happened to me the first time: L1 was connected the wrong way, oscillation did not start and the transistor got quite hot...

Hi
I put a heat sink on the transistors.
Can not find NTE2354, but I find that some of BU transistors are alike and I can buy them.
(2508A, 2508AF, 2520D, 2520DF, 2525A what do you think abot them)
I dont have osciloscope.
What does it mean "swapping"?
Transistors 2N3055 are OK. They are not from same manufacturer so they might not be the same quality.
Battery is 12V/6Ah.What is the limit for this carger?
