After I fully charged the battery, it only ran the iLife V8s vacume for 40 minutes before the battery had to be recharged. I was using it on slow speed and it should have ran a lot longer. I don't recommen it.When I placed the order the listing said it would be delivered Sunday. After I ordered it the delivery time change to the following Tuesday. That is bait and switch, pure and simple.Today, I ran the vacume the second time. The battery only lasted 11 minutes. the battery I received is junk.
