Query: B&D 3.6v grass shear

This shear worked OK for about a year. I use it with the extension handle and you do have to have a strong hand to keep both triggers pressed to keep the unit running. Now after a year, a full charge only lasts about 5 minutes. It used to work 15-20 minutes on full charge. I would replace the battery, but there is no replacement available.
