The voltage rating of capacitor should be least double operating . A. It might be worth putting a bigger heatsink on the transistor just safe. Stefan Vorkoetter May Chris first there are some points to keep mind circuit basically has two states charging not . Insert the thermistor through holes and then put pair of AA cells holder

F V capacitor Q TIPC PNP transistor case Z LM dual voltage comparator IC DIP LED Red green yellow mA Other cell AA battery holderUSB cableSmall heatsink Note that Radio Shack thermistor has been discontinued. As the cells reach about charge rate of increase will speed up again. Installing the battery holder is next step. It has lower current rating than TIP instead of but will only be conducting about
