How to Recharge a Black & Decker Rechargeable Weed Eater

Using a rechargeable Black & Decker weed eater represents a far greener approach to going after weeds that sprout in your flower beds, sidewalk and driveway than its gas-powered cousin. You generally can expect to work for about 20 minutes on a single battery charge before you will need to recharge your Black & Decker trimmer. Because the weed eater's 18-volt lithium battery can take up to an hour to charge, it's a good idea to have a back-up battery on hand to allow you to finish your yard work uninterrupted.

Instructions

- 1
  Insert the plug of the charger that came with your Black & Decker trimmer into an electrical wall outlet. Remove the spent battery from the trimmer by depressing the release button near the handle and freeing the battery from its compartment.

  Check to see that the air temperature is between 65 and 75 degrees Farenheit, which is the optimal charging temperature. Place the spent battery in the charger and snap it into place. Observe that the LED light on the charger is flashing to confirm the battery pack is charging.

  Wait between 45 minutes and an hour until the LED charge light quits flashing. Remove the battery from the charger and reinsert it into the trimmer's battery compartment and resume your yard work. Unplug the charger from the wall outlet once the battery has been recharged.
