I recently purchased this battery for my aging 600 series Roomba and so far it has worked like a dream. Many of the negative reviews complained about the install and how the battery life didn't last. I've only been using it for about a week so I have to reserve judgement on the longevity but the install was super easy and there are no rattles. Best part is that the battery came charged and I sent the robot around the living room for almost an hour and the only reason it stopped is because it announced that it had completed the job. I'm going to make sure to use it more often and to unplug it when not in regular use to save battery life. However, for the price I do recommend using this item in order to save on not purchasing an official replacement battery or a new Roomba itself. Update for this product: I purchased this last year and at the end of the summer of 2020 my vacuum started having issues with not holding a charge. It would run for 15 to 20 minutes and then quit. I contacted the company via email and explained the situation. They were very kind and said that it was out of warranty but would provide a 10% off coupon for my next order. Considering how cheap this battery is compared to the official iRobot product I figured is still better than buying another cleaner. During the time that of my correspondence I was asked to take a picture of the battery to send to them. My wife had cleaned the vacuum and tried other tricks to try and get it to work but she hadn't opened up the battery compartment. I removed the battery and discovered debris had built up to the point that it was blocking the battery terminals. I cleaned the area and placed it back on the base to charge. While I waited for a response from the manufacture, I continued to use the cleaner and it went past the 20 minute mark. Actually it went for an hour and returned to the dock on its own energy. It has been working fine since I cleaned it and I think it is the crud that I cleaned out of it that allowed the battery to get a good charge. For those that have the same problem please try cleaning it out and if it still doesn't work then contact the manufacture and see if they can help.

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.

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.

Revived our roomba

Very good product

Update: after buying a battery directly from Roomba, and that battery showing error three again, I called Mbah customer service, and they told me that error three means my machine has a charging problem. My old Roomba cannot be fixed. This battery is the same battery as the one that Rumba sent me. There is nothing wrong with the battery and I would encourage anyone who needs a new Roomba battery to buy it because the price is very good. Thank you to all who tried to tell me about the wheel height. I followed the Roomba companies, technical instructions and cleaned all my wheel wells, etc. Disregard the rest that follows… bought this a few years ago and I'm sorry to say that I forgot to post my review. I didn't put it into the vacuum right away and once I did, I got an error message from Rumba and the vacuum didn't work. I just let it sit around, because it was one more thing to deal with. Buyer beware… Or at least try it right away and return it if it doesn't work. One more thing. I just bought a Roomba 694, and I decided to try the battery that came with it in my old Roomba. Guess what...my old Roomba works! The problem was the battery, for sure, for sure, for sure
