Fusionchip's Bedini Feedback to Source!!!

Hi Fausto,
                 
                Another thing who can play alot, is to know what type of charge the battery take when you run your setup.I made some experiment long time ago with the full bedini cap setup. What ive found interesting is when i used realy low capacitor , like 0.1uF, the voltage of the charging batterie was climbing realy realy fast , after 3 hour of charging i let the batterie the time to stabilize. 24 Hour later the voltage was 13.4. i found interresting to see a voltage like that because i had drain the battery to 11.5v before recharging it. Ive put a load on that battery to discharge it under the c20 rules and found it droped instantly to 12.3 volt, it ran for about 40 minute untile it reach 11.5v.

This experiment is easly replicable , there nothing special in the setup but it show clearly that a battery can show a voltage who is realy not representative of what is inside the battery, that can be realy misleading. Its like a static charge.

This is an interesting effect also seen with direct HV charging from an energiser with a considerable power level. The battery is highly pressured because there is little rest period between pulses which I think has the effect of highly charging the electrolyte which can result in a high terminal voltage. When this pressure is released there is a marked drop back in voltage and this continues under load until what is termed the 'surface charge' sometimes termed 'fluffy charge' is drawn off to leave 'plate charge' or 'deep charge'. Bedini advocates using any surface charge as soon as possible before it naturally dissipates over a period of time as it effectively represents capacity gain if it can be effectively transferred to a load.

By using larger caps the capacitor more effectively buffers the battery from the pulsed high potential pressure resulting in the charge being more efficiently absorbed by the plates as the capacitor transfers a higher current level at a lower voltage. Bedini advocates just a few volts above terminal voltage for best efficiency cap pulsing. The high voltage, high pressure pulsing is I think good for fast conditioning - desulfating but not for efficient charging. The Bedini 1 ohm test is a means to ensure that the coil discharge power level is not too excessive in energy level to cause inneficient charging. A slow and steady increase in voltage with little drop back is the preferred charging method to ensure best conditioning and battery life.

I have a question for my honorable friends:

If I use three 7.2v NiMh in series to run this circuit consuming about 7 to 9ma, how long do you guys expect this to run to be considered above COP of 1 ?

I need three batteries because my circuit is tunned for around 20 volts and I dont want to change it now.

Is it ok with three batteries like that in series or is it too much too?

The batteries are in the picture.

Please, let me know.

Hi Fausto,

               i think its realy good, in a perfect world your setup should run for about 17 hour (with 3 7.2v in series) so let say you are able to make that even better ,if it run for 24 hour without loosing anything that will be realy great, but dont forget one thing and i think its the most important, put a load on it at the end to discharge the battery to know exaclty how many usuable mA you are able to extract after your 24h run test. if it run the fan for 24 hour and 12 hour on a bleeding resistor for the last discharge that will be a fullproof.

@ Fausto

From what I remember written or mentioned somewhere, the NiMh batteries were NOT recommended in the bedini circuits.

I personally have tried them in a shielded cage and they didn't blow up, but then I didn't get OU with the circuit I was playing with at the time 

That's my 2 cents.

I have had no problems charging Nicad's or NiMh batteries with Bedini energisers but as to whether they fully benefit from Bedini charging in terms of capacity gain through the conversion of negative energy, I have no idea. To establish the absence of the charging effect using other types of battery would IMO be as important as observing it because it narrows down the search for the cause of the effect.
