Unless the battery has been abused somehow, emptying the cells
contents make no sense. The sulfur comes out of solution in the
battery during discharge so you really should try to allign the ratio of
electrolyte to water concentration with the level of charge the battery
was at, at the time you emptied the contents.  of conservation
of matter says you would only ever need to replace water which
evaporates or gets electrolysed out of the cells. Adding commericial
battery additives is the exception. I've heard of  the battery,
off with, but not putting  into a a/l battery.

:S:MarkSCoffman

Apologies for the mis-communication.  I didn't mean adding baking soda to the battery, it was for neutrilizing the solution that was poured out so that when you throw it away it doesn't harm the surrounding environment.  Also, for safety reasons.  If you got some strong acid on yourself I was told that throwing on the baking soda and washing would be helpful

Hi niofox, thanks for the reply. I did try the circuit you posted and could not get it to oscillate, are you briefly connecting from collector to base to get it started or something similar, because i dont see what is biasing the transistor on. If you flip the switch as shown no current will flow through the primary because no base current is flowing. Would sure like to know how your getting it to oscillate, thanks.
peace love light

Hi Niofox yes about that schematic I had printed it in the past from someone else. Does that mean that one has to put all coils on to one?. Or one bifilar and the secondaries as single coils?
Today I tried a bigger awg coil but could not oscillate with my setup  :-\
Ok thanks anyway.

Hmmm, it may be possible that my project board has something shorted that is making it work.  After I get done moving this weekend I will try to construct it without the project board to see if it works.

The coil I am using is a bifilar #23 + #26, 1/2lb total weight, 12"x6" oval (no spool).  Not sure about length or # of turns.  I put some tape on to keep it tightly together

I am using a switchable adapter as my input.  Its set at 15v but outputs 19v under load.  Rated at 2amps max
I have not tried using 2 batteries in series yet, but I don't think it would oscillate at 12v.  It seems like the initial switch on kicks it into oscillation

I am sorry I cannot test things now.  By Monday or so I should be settled in at my new place and will start on this then

That circuit is good for a certain lenght of coil I think. This new coil that I did was not oscillating but when I shortened it a little there's a hissing sound. So now I would do a lesser resistor than 10k and I think it would oscillate. Cross fingers.

Ok, I have tried with 12v source and it works.  But it charges faster with higher voltage (I use ~19v adapter)
I removed everything else from the project board I'm working with and check various points for shorts.  It all seems to be wired as shown in the attached diagram.

I tried using a 200v 440uf Cap in place of the charging battery to get an idea of how large the spikes are.  I had to add a 2nd one in series to get the total ~250v.  The size of the resistor I use determines the time it takes to charge the caps.  ~440 ohms was what I found to be a sweet spot. 
The input was measured at ~410ma x 19.1v = 7.831watts
Time to charge the caps to 250v was ~10seconds
1 to 2 seconds after charging begins the neon lights up due to resistance of the caps as they fill I'm guessing.  Unfortunately I cannot hook up the battery at the same time as the whole spike goes to that instead of the caps
I may try adding it in with a resistor but I think the neon will just take it as before instead :/

Hi Niofox interesting about that circuit. Now I am using Groungloop's circuit. It consumes more amps but charges faster.
Thanks

@niofox;

I think he means the one with link starting here:

http://www.overunity.com/index.php?topic=9157.50

If you want to boost the charge voltage, what I would
do is extend the sense winding with more turns
leaving the base connection where it's at then
rectify.

---

You can't use wall adapters above their listing
current. Plus battery charging is somewhat unstable.
Batteries shouldn't heat up while outgassing
extensively, so I would not go to ever higher
charge power without limiting the voltage.

Hi someone had post this battery swapper in the past but this I think needs a third battery no?
Anyone knows of a good battery swapper with least components?
The box down is a 555timer.
Thanks

Hi Guruji,

The circuit is another switching circuit using the radiant back emf from the inductor to charge the battery. The 555 operates the relay with the opening and closing contact action performing the inductive switching. I have been experimenting with various radiant and cap charger circuits.

Hi Guruji,

The circuit is another switching circuit using the radiant back A from the inductor to charge the battery. The 555 operates the relay with the opening and closing contact action performing the inductive switching. I have been experimenting with various radiant and cap charger circuits.

Hi Crowclaw yes it uses a relay but there has to be another battery for source yes?
Did you try this circuit?
Thanks
