@lon92,

Did your third battery charge up?

Test with a 12 volt light bulb, if you get light for a long time then
your third battery is not "dead".

How warm did the battery get? Smoking hot or just warm to the touch?

@ lon92

It's hard to tell from the information you posted whether your experiment is a success or failure.  You would need to post information such as the voltages in the batteries at the start and stop of your experiment as well as the size of the batteries used and motor description.

Please read through the document mentioned in Reply #182 http://www.overunity.com/index.php?action=tpmod;dl=item183 , it should shed some light on the process involved to make this work, there seems to be several variables that will make this NOT work so try to stick to the original components used by David.

Hope that helps  :)

Regards,
Paul

Thanks Groundloop and Goat for your fast reply...  :D

@Groundloop
The battery is just warm to touch, not to hot...  ;)

I just tried put a headlight to the third battery, It light up brightly for a very long time...
My meter says it was 7.8 Volt...  :P

Not a dead battery...  ;D


@Goat
Thanks Goat!! I never knew about that file!!  ;D

I just read the document. I found that all of my procedure were correct...  ;D

Both of my batteries were fully charged...
After running test, my first battery was 9.9 V, second battery was 8.3V and third battery was 8.3V...

The weird effect is 2nd batt. and 3rd batt. were the same volt... Hmmm...  :o


@All
Well, it looks like Groundloop just proof me wrong...  ;D Thank Groundloop!!  ;)

Now I need to search for new dead battery...  ;D


Thanks again!!!

Hi all  ;D, im still in the process of 'killing' my 'bat3' - after i discharged it i went for another charge and drain cycle and went to charge it up but it blew the 30amp fuse in my charger  ???is this normal? am i supposed to let the battery 'settle' for a while before charging it? cause i had it shorted for a couple of hours after the bulb drainied it then i had a gap of 2 mins the hooked up the charger and full current showed on the meter for one second then pop and a dead fuse!
i dont want to keep replacing fuses like this and it seems pretty harsh thats why i was wondering if its normal lead acid characteristic?

thanks,

@Anothertruthfinder,

Yes, it is normal. Use a 100 Watt car head light in series with the plus wire going
from your charger to the plus on the battery. This will prevent a blown fuse.

@All,

Did a test today with my 42 Ah batteries. Here is what I logged:

"Test of David Bowling's Continuous Charging Device

All three batteries are FIAMM-GS 12V 42Ah.
Load are 12 Volt 25 Watt/h light bulb.
Motor is a MABUCHI RS-775SH and also a LESHI FRS-550PM 60023-12V.
The LEHSI motor is from a 12 Volt drill unit.

START VOLTAGE:

Battery 1 = 12.69 Volt Charged
Battery 2 = 12.71 Volt Charged
Battery 3 =  0,37 Volt Not charged.

Test start: Time=20:00 Motor does NOT run.

Motor starts to run Time=20:05
Battery 3 climbed to 14,29 Volt in 5 minutes.

Time=20:20 Disconnected motor.
Battery 1 = 12,47V Battery 2 = 12,48V
Battery 3 dropped to 7,5 Volt in 5 minutes.

Time=20:25 Connected motor again.
Motor is running, waiting for motor to stop.

Time=20:35 Motor will not stop. Disconnected motor
and connected a new motor. The new motor is
a LESHI FRS-550PM 60023-12V. Motor did run fast
and light bulb went down to dim.

Time=20:45 My "dead" battery has charged up to 10,40V.
Battery 1 down to 12,42V and Battery 1 down to 12,40V.
Motor running steady at high speed.

Time=21:00 Disconnected the motor. The "dead" battery
has gained voltage to 10,67V. Connected the light bulb
across battery 3. The light bulb did light. This proves
that my "dead" battery is NOT "dead" enough.

How to kill a battery? That is the question."

Groundloop.

thanks @groundloop - just shows my lack of knowledge in this area lol but ill be careful and follow your advice - i will have a dead battery one day! hehe

i was looking at original photos of davids setup and i believe he said it was a golf cart motor, i found something similar on ebay with gearbox - http://cgi.ebay.co.uk/180w-12-Volt-DC-motor-gearbox-unit-for-golf-trolleys_W0QQitemZ170230452097QQihZ007QQcategoryZ40155QQtcZphotoQQcmdZViewItemQQ_trksidZp1742.m153.l1262

this is 180 watt now assuming its similar wattage etc. this baby draws approx 15 amps, david had 18ahr batteries - similar ratings, just wondering if thats maybe a prinicple of it to have a motor thats just below one of the battery's ahr rating in the circuit that would then make for easier scalability and replication.

thanks again,
eel

@Anothertruthfinder,

You maybe right. I do not have to same motor or batteries.
Also, it is very hard to "kill" a lead acid battery, it seems.

I did see the motor "did not run at first" when the "dead" battery was close to zero ( 0,37V) volt.
But after a while the "dead" battery gained charge and the motor just speeded up.

 @ groundloop - time will tell i guess also when i finally get my dead bat3 i think i'll be at the very raw basics with just the 3 batts and a motor and see if i can replicate the initial signs david had with just those components
@ all - keep up the good fight folks!

Try hooking up the battery to a lawyer or a politician...that should drain the life out of it. :)

@ Cap-Z-ro  ;D

Hi All & DBowling

I've been going through David's posts in http://www.overunity.com/index.php?action=tpmod;dl=get183 and at Reply #146 I found the answer to the dead battery issue:

" First flipped the switch, NOTHING happened. The motor did not run. I sat around for 15 or 20 minutes talking to a friend, and suddenly the motor started. It ran until all three batteries were fully charged, and then it SHUT ITSELF OFF. Battery 3 slowly drained and then it started back up again ALL BY ITSELF. It repeated this cycle over and over and over for several DAYS. I just let it run. If you flip the switch and yours starts up, you know that you do NOT have a dead battery in the #3 position, so go find a DEAD one."

I think that pretty well sums it up as far as dead batteries goes  ;D ;D

Problem still lies in the details though and I'm afraid I'm a little ADD (Attention Deficit Disorder) when it comes to details, I often take things too literally which is often embarrassing  :P  So I'm slowly picking at it....

Regards,
Paul

@Goat,

I measured my "dead" battery today. The battery was disconnected for 7 hours.
It was down to 2,3 Volt. This means that I DO indeed have a "dead" battery.

>>"It ran until all three batteries were fully charged"

I have a problem with this statement.

My batteries do not charge when the motor runs, they drain.
Also, I did not get the "stop motor" when the "dead" battery gained voltage.
Maybe I need a bigger motor?

So, what are we doing wrong?

Groundloop.

@Groundloop

As far as your experiments goes I cannot help you or anyone else unfortunately, this seems like an experiment that only the right conditions will work according to the inventor (David Bowling). 

That is why I would like to get as much information on how to replicate this anomaly, I still have a few things to clear up.

I ordered the motor you mentioned earlier (thanks  ;)) and still have a few questions on the different setups but that's for later :P

At one point there is the mention in Reply #146 where the circuit ran for a few days where the motor would turn itself on and off as battery # 3 would charge and discharge so I think the dead battery along with the right motor and batteries plays a big part in this.
 
I would like to start at that point of the experiment, using David's original components and start replicating his findings one step at a time :P then I would like to progress to the inverter running a light load like David mentioned.

Unless I can duplicate his original experiment I'm afraid I can't help anyone.

Hope that helps.

Regards,
Paul

@ Dbowling

Groundloop & Myself are at an impasse at this point from what I'm seeing.

Is there any way for you to list all the components that you used in the original experiment that made the setup run for 3 days, I know the dead battery is tricky at describing and hopefully the document of your posts makes it clear to everyone that the dead battery seems to be the KEY to making this work, other than that thanks for your posts and continued support.  And please correct me if I'm wrong.

Regards,
Paul
