Its a Diode bridge that you use to charge the battery

OK
You mean the diamond thing? I bought some 4007's to make a new bridge, but didn't do it yet.

REALLY? sometimes I get 60 to 100 volts on that thing. Won't it overcharge the battery?

thank you I did not suspect that it was ok to do that,

What is empty voltage ?

It  looks to me like your friend is very well educated .
It looks to me like your  friend   learned  all he knows  without questioning it much.
To me  it is clear that the  curriculum  of even our  best  collages  has been  tweaked by people  that  have a vested interest in  keeping people   hooked  on  their  power .
The  "quirks " that we could  use to get OU  are   simply not   discussed in  any detail .....they are not studied .
How to get around these quirks is  taught in great detail

It is  good to trust  your friend ...........but just because he has a good education   does not mean he has the real facts .

Trust what is on your workbench .
If you can power  something  with   a battery you recharge  with  your system  ........who cares if the  voltage is " empty "   

Keep  up  the good work

what the friend is saying about "empty voltage" is the same reason why i do not practice using a bedini motor.  when you send a high voltage to a low voltage battery you "artificially inflate" the voltage on the battery. basically the battery stores a higher voltage but does not have any amps to back it. the amps is required also to do work. 

if you want to know if you have "empty voltage" in the battery measure the voltage of the battery when its fully charged from a regular charger. then discharge it and recharge with a bedini or JT to the same voltage and discharge again. time the discharge on both occasions and you will see what the true work is. if they are relatively the same then you have a full charge if they are different then you have empty voltage.

... if they are relatively the same then you have a full charge if they are different then you have empty voltage.

Of course all of our leds use empty voltage anyway, so why not?

@all

Why not take amp reading on the battery , be careful if you do !

But if it only gives out voltage and the amp constantly go down , we will still manage any jt circuit from 30 mili .

Now if that is so , how long would that take and also how many time can you charge a rechargeable.
