A Dewalt charger has LED indicators, and each of these lights has its own meaning. When a Dewalt charger shows a blinking red light, it means that it is in charging mode; you are not to unplug the charger until it reaches its maximum battery capacity or until the blinking red light turns to green.
If the charging indicator on the battery charger is showing solid or flashing red, this means it is properly charging the battery and the battery is accepting the charge. The older the battery, the longer it may take to recharge but batteries will generally recharge near fully.
One may also ask, what does it mean when my portable charger is blinking? Some chargers blink slow, about once per second, to indicate a good charging current, and blink faster, about twice per second, to indicate a battery problem. When the charger is fast-blinking, it will not charge the battery, so as to not overheat and cause a fire.
