I ordered this battery to replace the one in my Black and Decker cordless weed trimmer - and by the way, the original battery lasted 12 years and I have used the trimmer once or twice a week in growing season the whole time.  I got an "item shipped" email within an hour of placing the order and received the battery the next day, using the free shipping.  I let my trimmer charge and have used it twice with the new battery and I am able to trim around my entire yard and edge my sidewalks with no sign of the battery running out.  So far I am very pleased.
