This could be the only charger you need to recharge all of your DEWALT power tools – unless you have one with Univolt batteries. It charges Ni-Cad, NiMH and Li-Ion DEWALT batteries in 1 hour or less thus minimizing downtime. The LED indicates various stages of charging such as charged, charging, power line problem, replace pack, and battery too hot or too cold. The 3 –stage system extends the life of the battery and provides maximum run time. Imported.
