I have my doubts whether this circuit is working with an almost exhausted battery. Even without analysing it, I see a zener that requires 10mA to do what it has to do. At the 4.7V it means a 47mW, a lot of power from an almost exhausted battery. Did you really build this circuit? I like to see the results. petrus bitbyter

Mind you, my main PC monitor stopped working so what you are seeing in the middle is its power board where I'm about to replace four electrolytic capacitors that have inflated up until their death. Turns out the manufacturer used 16V parts for the 15V rail, except for the only one that survived which, unsuprisingly is rated 25V...
