I cannot actually review this item because it was a replacement battery for the Roomba of a relative. As far as I know, it worked and so did the filters.

This is the first replacement I had to purchase for my Roomba Discovery. I have had the Roomba since Christmas 2006 which was a good two years of running the Roomba 5-6 days a week. I recently acquired (2) Dogs, Rott & Lab so the Roomba has been working over time picking up the hair before the battery life started to wane. I did try re setting and that gave me some shelf life, but alas it was time for a new battery- well worth the money!

After the original battery could not be recharged I ordered a new one from Amazon. It lasted less then three months and I can not recharge it. I have gone through all of the discharging / recharging steps recommended by IRobot without success. Further inspection indicates the pack was remanufactured and probably has a bad cell. Stick with new from IRobot.

My battery was out of warranty and not holding a charge. Swapping them is pretty trivial... and it's a battery, it does what batteries do :>

After having my roomba for about 2 years, the battery got to the point where it only lasted about 10 minutes per charge. After trying the method by another reviewer to extend its life (a method which, for me, didn't do anything), I decided to fork out the money to buy a new one.

I couldn't be happier with my decision. Since replacing the battery, it's like I have a brand new roomba again. Rather than 10 minutes, it can go a few hours at a time before it gives up and goes to its dock for a recharge.
