You have to use constant current circuit anyway.
 

Re: battery charging

Why don't you start asking giving all possible details:

I have an 1.2V Ni-Mh cell 2200mAh. I want to charge it from a 3.3V using constant current generator...bla-bla

How do you want an answer if you don't know how to ask?

A Li-I battery can't be charged directly from a 3.3v for example...
