I want to emphasize the need to condition this battery properly when you use it for the first few times. You must run the battery down until it is completely dead, fully charge it, and run it down again. Repeat one more time and each time you do this, you will see how the battery holds more and more of a charge.It arrives with a really good charge on it. I don't know if it was fully charged but it seems like it was. I used it to clean three large rooms before it ran out of juice. I made sure it was completely dead by starting it up a few times after it reported "Charge Roomba" until eventually, it would not move at all.I then gave it a full charge and ran it again. This time I did the same three rooms and then I did them again, and then again. I was starting to think that this battery would never run out. This battery is so much better than the original Roomba battery. Now, the battery is new and I don't know how long it will last but my initial experience has been excellent. I will update here again when the battery makes it through the one year warranty period.I should point out that the surfaces the Roomba 770 was dealing with were not easy ones so the performance is even more impressive given that. For example, there are a few small thick carpets on wood floors that the Roomba has to fight to climb up and over. There are also many raised obstacles when the unit passes through rooms that consume more power than a standard flat wood or vinyl floor.I did have one issue when I first installed the battery. It ran fine through the first run but when I plugged it in to charge, it would not recognize the battery. I got a "charge errro 1".I did a reset per Roomba web site but still nothing. I remove the battery, used a wire brush to brush off the contacts on the Roomba, put the battery back in, and all was well. At first I thought the battery was not thick enough and perhaps needed a small piece of foam on the top to press it against the terminals but in the end just the cleaning did the trick. If you do have this issue, try cleaning the terminals (your old battery might have leaked a little on them) and if no luck add a little bit of foam spacer between the top fo the battery and the battery cover.As others here have stated, if you do have an issue, post it here in the reviews to get attention. I wrote to the support address provided in the box with the battery but after four days they have not responded. As it turns out, I don't need any support at this point.

I was a bit hesitant to order this based on some of the reviews, but I am happy to report that our 600 series Roomba has been working great running it over 2 months. It has enough power to finish cleaning our main floor and find it's way back to the dock. I would recommend this replacement.

Works fine, easy to install and more working time. It's perfecto for Roomba 671.

Great price but doesn’t operate sweeper as long as original battery. Cycled charged to empty three times but only runs 80 minutes versus 140 minutes for original batteries. Not a game changer though. Happy with it!

I also purchased this battery earlier, and it still works well on my other Itobot. A good buy and price

Putting my Roomba back to work 🌞

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 changes March 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.

The product is good but when the delivery date (14th) tracking had it “out for deliveryâ€, it never arrived. Later that night the date was changed to two days away (16th). Then to my surprise it showed up 15th…

This was a very affordable option for my Roomba. It arrived quickly, was easy to install, and had my Roomba up and running in no time at all. It has given it a new lease of life which is awesome

After doing a little research, I found this on Amazon - which was 1/2 the price for the exact same battery - The Roomba is now back up and running fine. Its easy to install and only requires a screwdriver
