I have a Milwaukee 4Ah battery. After charging it, the charger light is green. Removing and reinserting it, the light immediately shows green again. However, when I press the fuel gague button, only 3 of 4 lights come on.
The battery reads 19.75 volts, so I would have expected all 4 lights to come on (my understanding is that the gague is a measurement of voltage, not Ah capacity). Could this just be a burned out LED, or is there another possible explanation?
