How to Charging the Battery for a Cordless Screwdriver

An electric screwdriver must eventually be recharged.

Electric screwdrivers are incredibly popular tools that make construction projects much easier. In the past these screwdrivers were attached to cords, requiring the use of clumsy extension cords. Today, however, electric screwdrivers are battery-operated allowing total freedom of movement. Eventually these batteries wear out and must be recharged. The charging process differs depending on if the battery is built-in or can be removed, but both are equally easy.

Things You'll Need

• Charger or A/C cord

Instructions

Removable Battery

1. 

   The orange clip on this screwdriver must be released to remove the battery.

   Remove the battery from the base of the screwdriver. This is accomplished by either releasing a clip holding the battery in place or by sliding a switch that unlocks the battery.

2. Insert the battery into the charger so that the metal terminals on the battery line up with those on the charger. A red light will activate when the connection is made.

3. Allow the battery to charge until the red light turns green.

4. Pull the battery out of the charger and re-insert it into the screwdriver. Press the battery until it clicks in place.

5. Replace the clip holding the battery if it does not snap in place automatically.

Built-In Battery

1. 

   An A/C adapter connects a screwdriver to a wall outlet.

   Plug the A/C adapter included with the screwdriver into the wall.

2. Plug the other end of the adapter into the A/C port on the screwdriver. Some models have a light similar to that in the previous section, others simply require a certain amount of time for charging.

3. Unplug the screwdriver when charging is complete, indicated either by a green light or after the required time has passed.
