Review on Hanaix 4800MAh Replacement Battery IRobot by Roxanne Medina

battery Excellent quality! This brought our Roomba back to life and added power to it. Roomba runs for 45 minutes to an hour with no issues and still has enough power to return to the charging station. Important NOTE! Make sure the metal charging contacts on the base and bottom of the robot are clean. It will indicate that it is charging but will not provide enough voltage if the contacts are dirty.
