A battery-powered weed eater that is made by Black + Decker can be recharged using a lithium battery pack and a special base unit. The base unit has a cord that can be plugged into a wall socket and a light that indicates when the battery is fully charged and ready to be used.

When to Charge the Battery

Most cordless yard and garden tools, including Black + Decker batteries, have built-in battery testers that can show if the battery is fully charged or almost empty. To test the battery life, press the domed button on the battery pack. If all three LED lights illuminate, the battery is fully charged. Two lights indicate that there is still a fair amount of battery life left. If only one light illuminates, the battery will not last much longer without a charge. If no lights illuminate, the battery needs to be charged in order for the weed eater to work.

If the weed eater starts to slow down or struggle when cutting through thick weeds, the battery may be almost empty. To check, try using the weed eater on an easy area, such as a few blades of tall grass. If it works well, it can be used a little longer. However, if it slows down again, it is time to charge the battery.

Recharging the Battery

To recharge the lithium battery, remove it from the weed eater by pressing the battery-release button on the top of the battery pack. Slide the pack out of the weed eater. Place the battery into the battery charger base, making sure it fits in correctly. Plug the charger base into a wall socket and wait for the lights to illuminate. A flashing green LED light indicates that the battery is charging. If there are no lights, remove the battery and insert it again, ensuring it is fully pressed down. When the battery is fully charged, the green LED light will stay solid. At this point, the battery can be removed or left on the charging base. It is recommended to unplug the charger to save electricity.

Black + Decker also produces other yard tools, such as hedge trimmers and leaf blowers, that use the same lithium battery and charging base. If you have purchased these items separately, make sure the batteries and chargers are compatible, as there are different battery packs for different yard equipment. Buying a spare battery pack that is compatible with your weed eater is a good option if you have a large property and need enough power to finish the job without waiting for the battery to recharge. Some weed eater models can also be used as an edger, making it convenient to take care of multiple yard projects without switching tools.
