Powerextra 5.0Ah 14.4V Replacement Battery Compatible with Roomba R3 500 600 700 800 900 Series 500 510 531 535 540 550 552 560 570 580 595 620 650 660 700 760 770 780 790 800 870 900

Fits as advertised. Quick delivery. Works well we will see how it lasts

Fit as promised, works like it should. Charges fast, Easy to replace and seems to be holding up well so far. My original battery was green and more rectangle shaped, so I was a little reluctant to purchase at first even though Amazon said it fit my Roomba. So if you're in the same boat, it was compatible and fit perfectly.

Works great

It works well but it took some time to get it charged.

This battery fit my older Roomba 650 perfectly and brought it back to life. With this new battery, it runs for at least 20 minutes before the light starts turning orange, indicating that the battery is getting weak. 20 minutes is a long time, and completely cleans the floor of our living room, dining room and kitchen.

Greta battery worked out the box, charged and no issues

The week of May 14, 2017 the battery has refused to charge twice. I ran the roomba and I put it on the charger and it blinks red. I leave it off the charger for a day or so put it on and it charged . Used it again put it on the charger and charge fine. Next time I used it I put it on the charger and refused to charge . Left it off the charger for a while put it back on the charger and it's charged and has a greenlight.So something is flaky I'm not really sure what I only use it about every two weeks using it twice in one week was because I had some construction in my house. I only use it in my bedroom because everywhere else it gets stuck or chews up a cord or something but it gets under my bed. And also get stuck on the dogs bed in the bedroom which I have to remove course that's not a problem with the battery it's a design of their unitSee update below !!Purchased November 15, 2016 failed March 10, 2017. Outside of the 30 day return window. I've use this less than once a week since I purchased the battery!!!Update woke up in the morning after the battery will not charge and it was fully charged with a green indicator.Have no idea what is going on with this battery. It has gone from one star to three. I will continue using it and update the review if anything changesMarch 18 Saturday the seller sent me a replacement battery and a complementary gift. Very good service I have had the battery a couple days and I'm not been able to put it in due to my health but right now it is charging without error and excellent service from the seller!!!March 30, 2017 the replacement battery shipped by the seller seems to be working fine !!! I appreciate their shipping a replacement battery.It is May 28 and replacement battery has been acting up since I got it. It will blink read and not charge but if you leave it in the dark it will eventually charge and go green. Then the next time you use it it might charge and go green with no problem or it might blink read for a while and then charge it's very sketchy. I've used it a couple times this week which is more than usual and both times it gave a charging error after trying to charge it. I put the original battery that came with it in there it charges fine and works. It's been about six months since I bought it I think was the original purchase so I doubt they're gonna be able to do anything.I went ahead and ordered another one since it is a deal of the day I figured it's worth $18 to try another one.I updated this review and it doesn't appear to have been saved. The battery sometimes chargers sometimes it gives a charging air and then you come back and it's fully charged so it's no logic to what's going on this is the second battery it was replaced at no charge once.

Battery works and is compatible. Cheaper option. I only got about a year out of it. Purchased before and same thing. So expect 12-18 month life span
