Update March 8, 2021: I had to update due to the impressive 90 minute run time I experienced with this battery today. Started my Roomba 571 at 2:09pm and Roomba returned to charging station at 3:40pm. It can't be better! I am very happy! Previous post: I used this spare battery in my 10 year old Roomba (571) about 5 times in my small living/dining room and it lasts about 50 minutes on one charge. and automatically returns to the dock, which is acceptable to me as my previous original Roomba battery only lasted 20 minutes and didn't automatically return to the dock when the battery was low. a week as this will ruin the battery. Always keep it docked and use Roomba frequently to extend battery life.
