Update: 10/09/2019 After I wrote a review they sent me a new battery to test. I already bought a real Roomba battery but tried it anyway for comparison. First of all I would like to say that the new original battery works perfectly and my Roomba is back as I bought it many years ago. Since this company sent me a new battery to test, I tested it for 2 weeks for comparison. I started the rumba the way I always started the rumba and it was at the scheduled time. Out of 10 days of battery room use, 8 out of 10 days were clean. That alone was a big improvement as almost every day the last battery just died in the middle of the room. The only problem is that this battery seems to take forever to charge. A real battery only takes 4 hours to clean my house, this battery takes 9 hours. I still haven't bought this battery, it's not a good replacement. I have a Roomba 980. The battery fits really well but it just doesn't work. It didn't impress from day one and I just gritted my teeth and bought a real battery.
