The current drain from the 12-volt battery is ~10 amperes when the vehicle is ON but not READY. No small flashlight battery can supply such current. As soon as the vehicle comes READY, the NiMH battery can start recharging the 12-V battery, but not before. The reason for the high current drain is that all the basic electronics (display, all the ECUs, etc.) are powered from the 12-V battery. See my measurements in the thread "Disconnecting the 12-v battery."
