I just purchased 3 and have purchased 5 or more over the past few years. Theses batteries are awsome, especially perfect for fdl3, fdl basic, and many other blasters I own. The size is quite perfect and performance is excellent as well. There's plenty of power and the battery last a long time as well(charge wise). Also ineven have the batteries I bought years ago still work, great quality. Take care of this battery and it will take care of you.
