Common questions
Yes. BLACK+DECKER lists cordless 20V and 40V string trimmers in its US range. Choose a battery platform and verify whether your preferred kit includes the pack and charger.
Compatibility depends on the voltage platform and product generation. Match the battery to the exact tool manual rather than assuming every BLACK+DECKER pack fits.
Use the model number on the tool to locate the official parts diagram and service information. Spools, guards and batteries can differ between models.
Search the official support site using the precise model code, such as LST522 or LST201. The manual covers assembly, line replacement and safe battery use.
