Battery works fine but it was hard to fit in my Roomba. Not too happy about the fact that the brushes don't spin.

We have an older Roomba, approximately 10 years old or more, and these replacement parts fit perfectly . I also purchased the replacement battery, but still have not needed it. I hope the battery life  is as good as the old one.

My roomba has sat in the corner for a year with a dead battery. I saw this extended life battery listed for a fair price and ordered it. It shipped promptly and fit right in. After an initial charge my roomba went back to work and runs quite a bit longer than it did with a standard battery.

My little Roomba was saved from the dumpster by this battery. It works like new again. I didn't think I'd be able to find anything for such an older model. Thanks Amazon and Tenergy.

The battery holds a charge however I wish it was clear the design is different from what we were replacing. It is huge!  It is built to tilt the laptop up with a bottom ledge. This makes the computer almost a full inch bulkier so placing it in your laptop bag is challenging if you do not have a lot of space. Dimensions are listed however an image would have helped better describe the replacements size & design.

The original battery ran the Roomba for less than an hour.  We timed this replacement battery and the Roomba ran for more than two hours.

It was just a matter of taking the old battery and plugging in the new one. Now my roomba can clean my whole house in one run without running out of battery again.

The battery has breathed life back into my roomba.  It was a drop in replacement.  I don't know how long it will last, but if it last 2/3's the original, I got a good deal.

My old Roomba started working as if it was new. I actually like my old Roomba better than the new I just bought the only thing was that the battery was bad. I definitely would recommend this battery.

Bought it for my new Roomba and it worked ok for a couple of days and then died. Wouldn't take a charge. Should have got the real battery from the Roomba website.

This worked great in my Roomba 560 and installed in a few minutes with just a #2 phillips screwdriver.  My old battery wouldn't hold a charge and was causing the Roomba to act goofy.

The battery from Powerextra seems in good quality -- it supported my Roomba 4210 for half an hour.  However, the Roomba has a problem of correctly detecting the battery's charging status.  After charging the battery for a short time, the Roomba would show the battery was fully charged, but in fact the battery had no power.  Powerextra responded my emails quickly, and accepted my return.  I really appreciate Powerextra's great customer services!

Just received the battery and it does work. The fitment is not good though. It was so tight that I had to slam it on the ground to get it off my drill to charge it. Havent gone through a full cycle yet, so not sure about how long they are lasting.

I noted one bad review "26650 didn't fit". It is true they are a VERY tight fit. A bit nerve racking in fact, but that worked well for my application. Be patient and line the battery up perfectly before pushing it in.

Batteries are kinda puffed up, as though their plastic cover was inflated.  As a result, they're a tighter fit than the stock battery.  I bit of extra plastic from the seams as well, but that can be trimmed with scissors.

The battery does what it was meant to do, which was to give you a couple of rounds per charge. However, the reason I gave it 4 stars was that my Roomba started to give me problems with this battery, battery errors. I simply kept charging it and eventually the problems went away. I have to attribute those problems to the battery since they appeared after I switched batteries.

I'm still very happy with the battery and It's definitely much better then the original that came with the Roomba.

Replacement for the original battery. Gives me ~1.5hr run time. Only quirky thing I've noticed since install is my Roomba only makes it back to the base half the time now. Don't know if the two are related.
