Yes Tom in this case where the battery is really dead the indicator worked just fine but normally the battery starts out with a full charge (hopefully) and drains as you fly the plane. Nicads have an abrupt decay an the end of their useful charge. Without a healthy load (300-500ma) these on board indicators may give you the ok signal to fly and then the battery dies shortly after take off. I don't trust any indicator unless I know what the load is when the reading is taken. You also need to learn each battery pack. Each pack will decay differently even though they have the same capacity. If you use an indicator relics you will see what I mean.
