hello everyone
it's been months i have been busy designing a battery based system, and for the sake of simplicity i had chosen to use an old version of 3310 NOKIA batteries along with it's charger, when i was almost done with the rest of the circuit, i thought to look at the output of the NOKIA battery charger, and i almost had a stroke!
because instead of the nice and smooth DC output i was expecting to see, all i could see on the scope was a half wave sine!
1) now! can anyone tell me what i should do with this sine wave to make it charge the battery?i am looking for some accurate design that would work.
2)i have another problem: the battery has 4 leads, i know from which pins it should be connected to the circuit to supply the 3.3V VCC of the circuit, but i don't know to which leads of the battery and how i should connect the charger!
these batteries so sensitive, they might be easily damaged or even expolde!
