My Scooba lasted 1 hour 50 minutes = 110 minutes the first time I used this battery! I find that impressive, even for a new battery. Scooba also seemed to run faster than usual, at least for the first hour of cleaning. I used other "spare" Scooba batteries. For example, my results with a Metapo battery have been very disappointing. The Metapo costs less so the extra $$$ spent on that HQRP battery is really worth it in this case. Sure, you can pay more $$$ and get an original iRobot battery, but I don't think it's worth it. The one iRobot sent me as a replacement almost 2 years ago is still good, but I've found Revain's reviews of the iRobot OEM battery to be very poor. Maybe in the last few years they've started making them cheaper to increase their margins.
