Charge your power drill battery using your battery charger.

DeWalt manufactures a wide range of cordless tools, including drills, powered by rechargeable battery packs. Most of the Dewalt batteries are lithium ion types which are lighter and last much longer than nickel-based batteries. However, every so often it's necessary to recharge your power tool battery pack, so you need to know how to operate the DeWalt drill battery charger.

Step 1

Insert the plug on the end of the wire from the DeWalt drill battery charger into an electrical socket. It needs to be an electrical socket that produces 110/120 volts, which is the standard voltage in most household outlets.

Step 2

Insert the battery into the Dewalt battery charger so it fits securely. It can only be inserted in one direction, so you can't get it wrong.

Step 3

Turn on the DeWalt battery charger. The red LED flashes to confirm the battery charger is charging your battery. Wait until the red LED stops flashing and glows continuously, which means the battery is fully charged and ready for use.


Step 4

Use the "Tune-up" button on your DeWalt battery charger to equalize the cells in the battery pack. Insert the battery into the charger as before and turn it on. Wait for the red LED to flash then press the "Tune-up" button. The LED stops flashing and then flashes quickly three times before it resumes flashing as before. Your battery is getting tuned.

Step 5

Wait until the LED glows continuously to indicate the tune-up is complete. The cycle can take eight hours to complete, so only do this when you don't need to use your drill.


Your DeWalt battery charger automatically senses the condition of your batteries and charges them appropriately. For example, if your battery is too cold or too hot, it adjusts the way it is charged and the LED light flashes either quickly or slowly. If your battery needs replacing, the LED light flashes very quickly. If there is something wrong with your power supply the LED flashes twice quickly then pauses and repeats the two quick flashes, and so on.
