Review on Dutyone 5000MAh Replacement Battery IRobot by Gloria Blue

This battery has not yet been rated. The first few times I started Roomba, the battery lasted over an hour. However, it begins to expire after about 45 minutes of the cleaning cycle. Then the battery will be discharged very quickly; Roomba went out of battery a few times. Considering it has a higher amp hour rating than the OEM I would expect the battery to last significantly longer.
