I bought a used Dyson V8 Absolute a few weeks ago, and I realized that the battery that came with it was not holding a charge like it should. After testing it a bit, I went online and found a reasonably priced one to buy and test. Sure enough, this battery charges faster, holds longer, and feels like the motor even runs better. The install was extremely easy (just three screws) and it also came with some filters. If you need a replacement Dyson battery, look no further - pick this up.
