Bedini Solid State Oscillators

[blackchisel97]

Hi blackchisel, thanks for info. Yes I have tried to charge primary cells also and have charged a few, but some pop or simply start oozing fluid out. I wonder if there is a way to modify these to withstand gentle recharging to get more cycles from them, like some kind of reinforcement to prevent the bursting effect.

With SSG you can change the wave to charge or desulfate -
this is a charging mode. In desulfating mode, "h" roundish part of a wave will be straight diagonally to the right and down to the bottom. This can be adjusted by changing base resistance (lowering). In solid state version you can adjust discharge timing thus, lowering voltage on dumping cap. For example; if you want to desulfate battery, you set timing for the cap to discharge @ 19 -25V. For charging you can go with 2 - 3V above battery or even less. However, alkaline batteries were never meant to be recharged

Hi chisel, not sure if you meant this jokingly as if to say, so they say "However, alkaline batteries were never meant to be recharged", but from what i've read the only difference is because the shell is not strong enough to handle the pressure built up inside and that makes it cheaper to build. Maybe you already know this.

That' what I meant -

I have a sense of humor too!

Hi Tyson.

Of course I was joking. But seriously, if we use a gentle charge without building pressure inside, which cannot escape than we can extend their life while protecting our assets. I want to get small solar panel to power them. Even solid state can be easily run by 12W sp.

Hi chisel ,ok I thought you were joking . Makes me want to try and charge some non rechargeables again.

I guess pop happen because alkaline based bubble more than acid based just like Bedini video show. This bubble make the battery pop.


Voltage reading charging gel SLA 12V 7Ah:
start at 12.37V, using output current at about 0.25A. input current is 0.7A at 10.5V.
00.00 -> 16.88V
00.30 -> 18.05V
01.00 -> 17.71V
01.30 -> 17.42V
02.00 -> 17.30V
07.30 -> 16.49V
22.00 -> 14.80V
40.00 -> 13.54V
50.00 -> 13.47V
1.20.00 -> 13.46V
2.00.00 -> 13.49V
2.23.15 -> 13.50V
3.17.00 -> 13.50V
4.33.00 -> 13.56V
4.55.00 -> 13.60V
5.24.00 -> 13.66V
6.05.00 -> 13.79V
6.34.00 -> 14.55 -> stopped
12.98V after two minute rest.

6 hour 30 minutes of 0.25 should equal to 81 minutes of 1.2A load.

Voltage during 1.2A (9V) load is:
in the first minute -> 10V -> 9.5V -> 8.0V -> 7.5V -> 9.0V
05.00 -> 9.40V
08.00 -> 9.42V
09.45 -> 12.00V -> at 1.4A, sudden increase of voltage during load???
17.00 -> 11.94V
20.00 -> 11.82V
31.00 -> 11.53V stopped

change of mind discharging again
jump of voltage happen again after one minute of discharging???
00.00 -> 9.25V
01.00 -> 11.70V
03.30 -> 11.00V
08.40 -> 9.25V
17.30 -> 8.48V stopped.

charging again
00.00 -> 13.00V -> 12.94V
01.00 -> 13.01V
03.00 -> 13.10V
11.30 -> 13.18V
32.30 -> 13.22V
1.01.30 -> 13.58V
1.44.30 -> 13.53V stopped.

Sudden voltage increase during load is weird.
Good thing previous voltage only charge gone after 1 charge of direct radiant. It seems to also make the battery refuse the charge by climbing voltage at the first hour of charging before it start show normal charging voltage. Second charging has much smaller increase before actual charging.


On alkaline, just trying some charging. I discharge 2.9V alkaline (two) until voltage during load is 2.20V. After charging for 10 minutes it become 3.2V with voltage during load is 2.70V. I guess this time the alkaline do take the charge. Since 10 minutes store some 0.5V of usable charge, I guess I should never push it to hard since 1.6V is the maximum suggested cell voltage for alkaline.

Tuning getting closer

Hi folks.

My tuning of John Bedini Solid State is getting better. After numerous changes of pulsing capacitor, finally settled with 2.0MF 400VDC poly cap. Dumping fully adjusted from 0.8V - 190V+ above charging battery. I don't think I would want to approach upper value. I can visualize couple gallons of sulfuric acid allover my bedroom Output current 0.050A on very sulfated battery. Below couple scope shots from my circuit:

555 oscillator duty cycle



Oscillating transistor - base



Switching transistor - collector

Is it true that your capacitor charging frequency is capacitor dumping frequency too?

Scope across battery

Hi folks.

There is another "step" in the upper wave part. I need attenuating probe. Pulsing 30V over battery. Battery reading 13.2V. Spent another night tweeking

Hi folks, Hi sucahyo, I noticed your thread over at rcgroups when i was search engining anyone radiant charging primary alkaline cells. Definitely an up hill battle in that forum, notice most replies you received were almost religious and some there seem set on there belief in lack and limitation and you weren't even mentioning free energy or anything. At any rate, I'm radiant charging 3 alkaline C cells in series from my led flashlight and are taking a charge nicely, made a quick test putting them back in led light and is working nicely, brightly lighting the 3watt led. We'll see how these cells work over time.

Hi Tyson,

Just remember, be gentle with them

Hi Tyson, I use that forum as a test wether I should ever mention this to rc community here. I don't dare mentioning OU or COP. They think coil collapse current is no different than other trickle charger, while every trickle circuit I found dispose the coil collapse current with either 5 watt (get very hot it seems lol) resistor after diode or worse, just diode.

I found that pushing too much current (1A) do not make the charge stay on nicad or on alkaline. I just found out that charging 100mA would also take an hour too for nicad. It also make the charge stay at alkaline. I gues I have to reduce the output current until charging 1000mAh require more than an hour.

Hi V-tech, I wonder how fast your transistor CE voltage fall time is? is it in micro seconds, since I see your scope show in mili seconds.

Some time ago people believed that the Earth was flat. For some, still is

I found that pushing too much current (1A) do not make the charge stay on nicad or on alkaline Battery will take what she needs. If you force energy into it she will eventually die.

That would be correct.
I work continuously for the past 5 nights. Mainly on this circuit. It would never cross my mind (if I still have any left) that such simple circuit may involve so much thinkering

I know what you mean lol.

I just charge 12V 7Ah with maximum output of my circuit, 220mA at 30Volt. This also heat up the battery as well. I guess even an gel SLA can heat up too. I think the ideal charging is not related to output current, but also to output signal quality. For my circuit I think it is when the transformer sing the clearest. At max output the transformer sing with some crackling.

I think the ideal charging is not related to output current, I remember John Bedini saying - it's all in the right waveform. Don't get distracted by IN/OUT ratio. I'm trying to find this waveform somewhere to compare.. but also to output signal quality. For my circuit I think it is when the transformer sing the clearest. At max output the transformer sing with some crackling.
