Dear Allan,

Thank you very much for the reply to my querry regarding the charging of 3.6V Battery. But I am not clear regarding the use of schottky diode in parallel with the resistance:
a) if the diode is reverse biased with respect to the VCC
then, when the instrument is switched off, the battery will get discharged through the diode
b) if the diode is forward biased with respect to the VCC
then the charging current will flow through the diode rather than the resistance and thus will not be a limited current.

Kindly clarify.

What I had suggested was using the diode in series with the resistance rather than in parallel But I am not sure about its working. Kindly help me out.

Regards,

Mohit
