You want a fire in your house ? you never ever charge Nicd/Nimh directly connection to the power source. There is always a current limiting Resistor in series. Either use a published circuit from new or buy a new charger. These Chinese ones cost less then Rs 100.

thanks uj , just tried for few minutes

so i cant use nokia chargers in series

Plz m. No share
