@Dopasetic The orange light means it needs to be charged....while charging the light will change to blue and then will stay blue till fully charged. Then the blue light will go out when it's fully charged.
Make sure you clean the charger and battery connections regularly. Some corrosion buildup is normal, and you need to remove it to keep a good connection. I am assuming this is a CF model?
Charger model ?
When you remove from charger, is the light then on (colour ?) or off ?
