I expected the battery to have a much longer life than it did. There has been no change between original battery life to this battery.

The first day of fully charge. The battery worked perfect. After day two. The battery only lasted for a short period of time and my vacuum only cleaned one spot.

Unfortunately it seems that the Roomba 980 is not compatible with this third party battery. Roomba does not start or charge and tells to "check that the battery is installed correctly"

Roomba 960 finishes quicker with this battery. Will update when i have a read on longevity, but for now this is a great product that I recommend.

I just bought this battery this week and replaced my OEM battery that came with my Roomba 980. There is literally NO difference in battery life of this one over the stock battery. So if you think you’re going to get more runtime, you won’t.

So my roomba never goes back to the base now. Also, I have done the "reprogram” multiple times and still get an error message. Unfortunately I don’t know about the error message until roomba misses a cleaning and then I check the app to see what happened. This is frustrating. I had hopes it would work but it only works with me resetting it after every use.Update 10/4: this battery was a complete waste of money! At this point Roomba will not start at all even though we he battery shows as fully…

I had a OEM battery go bad in less than a year. The Roomba was also not able to do a full vacuuming on one charge even at the start. This battery dropped right in with very minimal effort. After charging fully, the battery provides ample power for a full vacuuming without a pause in the middle to recharge. The extra power of this battery makes a critical difference for me.

First tried the Powerextra battery and it would not work, had to return it. Bought this one and the Roomba 985 recognized it, charge up and and has been running great. Used it one week. Runs strong.

After installing and charging for the first time all seemed well. That was until the Roomba docked to recharge. Every time it causes a charging error 8, which means the battery has stopped charging. You physically have to remove the roomba from the charger and put it back on to clear this error. Very inconvenient when you aren't home and want it to vacuum on a schedule. I would have returned it but the return window closed before I installed it and found this problem.

Battery installed simple as could be. After a few recharges it has an hour plus run time. Nothing to complain about. The battery may be more expensive than other third-party options.
