WORKED GREAT, GREAT PRICE, LASTED FOR A LONG, LONG TIME, FIT MY ROOMBA JUST PERFECTLY AND NO PROBLEM CHANGING IT, IT WAS EASY...

Perfect fit and works as expected

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.

Update: Dec 2017 -- RIP replacement battery. About a month ago I started noticing times when Roomba wouldn't run, but then I'd put it back on the base, let it charge, and it would go strong. The last week it's been pretty clear that it's all over for this battery. We got 18 months out of it. I lowered my rating to 4 stars. Original battery lasted for 5 years, replacement battery 18 months. Update: Jan 2017 -- Still going strong. Roomba ran for about 2.5 hours the other day. I don't know how much is luck with battery cells and how much is carefully following the conditioning instructions, but it's still working great. A month in and everything is working wonderfully. Our Roomba runs 5 days a week and run times are as long as necessary in our 2 cat, all hardwood household. I carefully conditioned the battery per the directions, fully charging (I let it sit 24 hours), then fulling discharging several days in a row up front. The instructions give very clear advice for conditioning that was good: Unplug your charging dock and tell the Roomba to go back to its dock. It will simply run until it runs out of juice. I did this each day for 3-4 days. I did have to empty the Roomba multiple of times the first day or two because it couldn't run that long without my doing that since Roomba had been dead for about a week when the new battery arrived. Now we are getting multihour runtimes where the old batteries had been lasting maybe an hour before they finally gave up the ghost. Product seemed well packaged, instructions were clear. No issues at all. I see other reviews complaining about short life. Right now I don't see it, but as you can see, there are 12 battery cells in this power pack. If you are unlucky and one fails you'll have problems. My guess is that in a quest to be cheap and pack the highest Ah rating possible into the pack that the cells may not be as robust as you would hope, so I plan to treat it nicely.
