The LEDs on my Dewalt charger do indeed change as per the diagram on the 
charger but I have employees who leave the battery on overnight or longer 
and the pack will be HOT to the touch no matter how long it's on.  That is

what makes me assume the charger continues to charge.
I did notice they sell a car charger. Is anyone using LiPos on the tools 
themselves?  I know we use them in planes. :)
I may have to invest in new batts.
