Where are the real arguments? If someone actually knows that Charles' circuit is dangerous, so please explain in detail,
1) thank you for doing so
2) again an assumption (NiCd) is made, Aymah has yet to tell us.

To me it seems that Ayman is less experienced.
my impression too, that is exactly why I have hammered against the patent solutions offered without even knowing if he believed he could recharge an alkaline (there were at a time alkaline rechargers available, they are no more because of exploding batteries)

Many people have lost their eyes and to tell that nothing wrong can happen when overcharging is just criminal. Especially for a professional...
Exactly

So, Ayman, who needs help would have to be told, that this circuit can only work, when supply current is much less than 10mA.
again you are assuming NiCd after warning against assuming.
