These batteries worked well but after 11 months they are down to 20 minutes of vacuum time. 2 batteries in 2 different Rumbas. Not good enough Note: the company read my review and contacted me. They sent me out 2 new batteries to replace the ones I bought. Changing to 5 stars. This is a quality company that actually cares about their customers. Great job!!

It's a drop in direct replacement for OEM part. No compatability issue at all. Has been charging and working just like the original. The long term test will be how many charge discharge cycles it lasts but thus far no surprises!

The battery fits perfectly and provides a significant boost in runtime compared to the original. My Roomba can now clean my entire home without needing a recharge halfway through. The installation was straightforward, and it charged quickly. I appreciate the added power, which allows my Roomba to pick up more dirt and debris. The only reason I’m giving it four stars instead of five is that I noticed it takes a bit longer to charge than I expected

Bought this battery as a replacement to the stock battery that came with our Roomba. The stock battery is about 4yrs old and run time started to decline. After 25-30mins, our Roomba would stop in its tracks in the middle of a job. I found this replacement and installed it right away. Installation was a breeze. Now, our Roomba can complete jobs with out suddenly stopping. I believe the full charge lasts about hour or so. Which is perfect in our case and what we need it for.

Battery does install easily and works with the Roomba, but battery life is trash. I’ve given it a few years hoping that more regular use would allow the Roomba to adjust to the new capacity or that a smaller living space would accommodate the poor charge, but no such luck. I get 40 minutes of cleaning before it dies, and the Roomba doesn’t recognize the decreased charge, so the feature where it returns to the base to charge itself essentially no longer exists. I’ve never once successfully completed a job larger than 1 room since purchasing this battery. Stick with OEM batteries.

I bought one of these four years ago and it’s time to replace it. I’d say it was a very good investment for my $22! Yes, I would recommend this battery. I’m buying another one today and keeping my old Roomba alive :)

Went in perfectly,charged and we are working well!
