Review on Dutyone 5000MAh Replacement Battery IRobot by Jill Smith

Fits perfectly but the battery doesn't last as long as it should compared to lower rated more expensive batteries. Roomba with the best battery: Keep going back to the charging station even though the light on Roomba is red. The cheaper, higher amp battery seems to shut down very quickly when the Roomba's light goes red and the Roomba never returns to the charge bay. The cheaper battery doesn't seem to have that last little nudge. Support contacted me about the battery. Told them the same thing and they asked for info on the old battery. When I reported that the old battery was being recycled, they didn't respond at all, leaving me in limbo. That pretty much speaks for itself.
