    Hi folks.

    Thanks for sharing good news Tyson Yesterday I got a brilliant idea - actually I'm making fun of myself- to do tuning, using decent battery instead of a dead one. Quite a difference! I used two 2MF 400V DC caps in parallel. I can hear them singing or chirping depending of frequency. I checked the wave over the cap. "Cleaner" sound means nicer wave and better charging. I tried with 25 - 22.5 -20 -17.6 - 15V on the cap. Best charging rate I've got was near 17V with clean wave, single pulses without a "ghosts". Battery is the same hd 1000CCA as the sulfated one which I've been testing previously. I put back diode parallel with duty cycle pot. I found tuning being easier this way. I also added 100uF cap between 4&8 and ground of 555. I think that stabilizing 10nF cap from 5 to ground will prevent from false triggering. Leg 5 of 555 is a comparator input. It's easier to tune with 100k pot being 10 turn rheostat. Base resistance has to be adjustable (for tuning) and no less than 2k.

    Congratulation for charging success Tyson . I think the key is just what Vtech mention, the right waveform .

    After reading two people on different forum mention that their radiant capacitor has become an electret (self charging) I decide to try it with battery since my capacitor also become an electret too although at much lower voltage (10V). If the requirement of capacitor to become an electret is by utilizing them in capacitor dumping circuit then I should try battery act as capacitor.

    Currently charging the battery in best cooling mode and 0.5 second discharging on every 30 seconds by switching the negative to 24V motorcycle rear lamp. The charging is faster now, I may change it to be equal where charging time make the same voltage differencial as discharging time.

    Hi folks, just want to let you folks know how well the charging tests of these primary cells are doing, duracell copper tops alkaline C cells. They remain stone cold when charging and using my led flashlight to discharge them I'm getting the same capacity one would expect from freshly store bought ones. My flashlight discharges at C/10 rate and flashlight lasted 8 hours with about 7 hours at near to full brightness. I remember in Joseph Newman's manual how he described these non rechargeable cells to be more ideal for this type of charging. Maybe that's why they put such fear in us of recharging them.

    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, 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.

    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

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. 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.

    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.

    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 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.

    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

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

    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.

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