Here are some more videos:

And the new Sanyo rechargeable battery:

Have a look at this.

Normal Alkaline batteries can be recharged,
if you don?t put too much current through it
and don?t leave it longer than 1 hour in the charger.

Regards, Stefan.

Yes i do this over years.
some companies sells also 1,5volt rechargarble batteries.
(Germany  Comrad  abaiut 2000/2002.

Ray o Vac i think from US.

The only problem is, its need an special recharger.
Bateries will leackage or explod if load with normal cahrgers.

If you reconstrucht your charger (zener-diodes  or 3x 1n4007) that the voltage can not come over 2,0 to 2,1 volts in the battery, than you can charging this "batteries" without trouble.

Give attention that the batteries will not think under 0,6 volts, SO this way, tey can be charged up to 25 times.

Be happy , with this knowledges.
Pese

P.S.
The batterie industry KNOW this possibility, BUT they are
NOT INTERESTED , that this knowledges will be officially
comes to the consumers.

This is an knowledge that disturbe the buisinesses.

Can you post a schematic for an alkaline battery recharger?


I have a whole box full of dead AA batteries.

use the normal -?pw cost- charger that aur to use for 1,2volts NiCad / or Metalloxyd batteries.
But they are not stabilised to overcharging volts Voltages.

The BiCad rechargable batteries stop to charge at approx 1,45 volts. And will not destroy the battery
with some hours overcharge.


BUT the charger will spend 4 to 5 volts in maximum (without loading batteries  connected !
So this is cause that alcalien bateries and also RAY-O-VAC specieal Alkaline rechargable batteries will destroy in this cahrgers BECAUSE they are  sensetive to OVERLOAD (in voltages).
They charge from 1,5 volts beginning even up to 2,2  2,5 and higher voltages, BUT they go hot will explode or leacking.

With 3 time 1N4007 (each have 0,7volt Vf)
sot the Voltage can stabilised at aprox 2volts (without batterie in Charger
If connected (between positive and negative pol )(att.: to polarity).

Attention all chargeable batteries  (any type) will be loaded with maximum 20% over the normal voltages !
1,2volt wit 1,44 volts
12 volts with 14,4  (example als lead acid  , enz)
1,5 volts at 1,8volts   enz.

so the alcaline are charged it the voltage arrived 1,8 volts.
to "shild them with 2volt diodes" is an protection for the battery,
if you have not the time to "observe" the charge.
Without this protection , alcalin batteries will die within 1 - 2 hours overloading with more than 2 volts
 
Have fun with this.
Recharge alltime before batteries are fully empty !!

Okay, so no schematic...

I think you are telling me to apply a reverse bias voltage at less than 2V ?     Is it better if the voltage is continuous or pulsed?  If pulsed, is there a proper frequency.  Thank you for the information, I am sure this will be very useful.  I save all my dead batteries, because I figured there would come a day when we could figure out how to recharge them all.

Is this site of any help?:

Hello,
your circuit is an CURRENT - Source (Limiter)
you must limit the Voltage.

youur cahrging alkaline must in the way from emiter to ground.

the diodes D1- x must chousen so that no nore than
1,8 to 2 volts can be cahrges to the alcaline cell.
The load current , can be limeted with an resistor (or Pot) tgat come between Collector and + suppli.
(in the wy , kow your cicuit shown the batterie now.

If need i will do an circuit by main , and scan this for this thead ,
i think its understanding now.

Hi guys

The Batboostor is (claimed to be) specially designed to recharge Alkaline and Saline  batteries (and also rechargeable batteries). ..

Gentleman;

Between 1990 - 95 (I think, getting old....LOL) I used to record late night movies on VHS and watch them later.....one day I happened about a late night infomercial about a battery charger on one of the tapes

The device was invented by a professor at McGill university in Montreal (I think, again!)  that had a round device with slots that accepted all kinds of normal batteries (transistor/AA/C/D etc.) and would monitor and recharge them and shut them down while continuing to charge the others    BTW...I found out in 2000 or so while taking to one of my closest friends about it and he seen one of the devices in a local store (Canadian Tire) and it wasn't there for long..... Typical !!!

I never bought the device back then (Kicking myself now....LOL) but anyways here's the kicker...

The inventor showed a scope shot of the charging secret...and guess what?

Short sharp shots...RING A BELL!!!!.....  As seen in many projects in this forum and all around the world for the last 100 years or so

Telsa said it in many of his patents....Short sharp shots of high voltage and high frequency   Does wonderful things... Dangerous as it maybe but it's all up to the inventor to take precautions...right?

To make a long story short, you can recharge normal batteries, I've done it with the bedini system while experimenting a few months ago as stated in:

http://www.overunity.com/index.php?action=post;topic=3793.msg67900;quote=67900;sesc=0a290752afbd769aef659e56a5c9af50

I was trying to experiment with the charging side impedance using an 8 x 1.5 V AA batteries @ 12 V setup and was able to use 2 of the freshly charged batteries in the camera until last week!!!  Yes it took energy from my source battery to recharge them so no OU there but it did save them from the landfill   

A while back I did a search for such a device on the web and it's still possible to get one (although not the same model I had seen) but check this one at http://www.theweb2u.com/

It would be interesting to hook up that model to a scope and see what output comes out and what it looks like   I would bet it's the old Short sharp shots of high voltage and high frequency

NOW YOU CAN:
? Save money by recharging batteries and safely extending their useful life
? Keep batteries fresh and ready to provide power
? Lower the amount of batteries entering landfills and their impact on our environment  (Not sure about this one if you're using the grid )

Later guys....keep pickin' at it...someday we'll get it

With respect,
Goat
