i bought the Black & Decker "Grasshog" cordless weed trimmer last summer (08). It comes with 2 rechargeable batteries. It worked great all last summer and fall. Then this spring when I used it, both batteries would not hold a charge. I could not even finish my small yard without both going dead. When I went to the hardware store to buy a new one, the bin was empty, so I assumed everyone else has this same problem. For the $100 investment, I'll buy a small gas operated one next. Disapppointed!
