OK! 552 Roomba with my old 3000 Ni-MH batteries which should only have lasted 45 minutes! I have a large wooden floor. Roomba can go under all my furniture without getting stuck! I paid attention to that during the repair! I hate looking for them and pulling them out from under anything! I bought these batteries thinking they would extend the life of my Roomba and yes I took the chargers with me so they couldn't go back to the charging station! 2 hours! Very happy! It's been 1 month now and I was just timing because they didn't seem to last that long! 1 lasted 1 1/4 hours and the other 1 1/2 hours. So if you think you won't get extra hours. Spend your money and get the best. From the start, I've been hiring these things twice a day! With my other batteries they would last 3 or 4 hours so I'll go back to the Roomba store and pay Piper if that means I don't have to argue with the stupid little robots I love so much! (Mom's little helpers deserve better anyway!)
