Hi, I have setup the circuit here: http://www.next.gr/circuits/nicd-battery-charger-l36249.html [Broken] in LTspice, and am trying to understand it. If I actually build it, its purpose will be to charge 19.2 V NiCd batteries. My question is if the regulated voltage coming from the LM317 output needs to be close to 19.2 V, or if only the regulated current (which should be around 150 mA) actually matters. The reason I would guess affirmative is if I say regulated at 9 V, then when the battery was above that voltage (like if I tried to charge a battery that wasn't completely depleted) a greater current would flow through the voltage divider than what is coming out of the regulator and so none of the charging current would reach my battery. Is that correct?
