| A Dewalt charger has LED indicators and each of these lights has its own meaning. When a Dewalt charger shows a flashing red light, it means it is in charging mode. Do not disconnect the charger until it has reached the maximum battery capacity or until the flashing red light turns green.
The red LED indicates that the charger is switched on (lower LED). The yellow LED (middle LED) indicates that the charger is charging the battery if it is switched on continuously.

DeWalt batteries charge quickly and last a long time and contain an electronic chip that shuts down the battery if it overheats. When the battery runs out, it needs to be restored. The reset process clears the chip’s memory and allows the chip to charge normally.
The battery must be fully discharged for this to work. Then, when it reaches zero percent, turn it back on until it doesn’t even have enough power to boot. Now plug the power cord (into an outlet) and let the battery charge for at least 48 hours.
