I replaced the battery in a 500 series Roomba, and it seems to be doing wellThe old one would not hold a charge. The new battery is doing well. No issue with the replacement. One out and the other one in!

I was hesitant to purchase this battery, due to some negative reviews. I took a chance. I wish I hadn't. The battery, for all it's supposed extra MAH above standard Roomba battery, barely added 30 minutes to Roomba's cleaning cycle,. After a week, the battery seems to have already developed issues, as reported by other negative reviews. The battery no longer charges or holds a charge properly. The battery no longer communicates it's status properly to the Roomba app. Battery status is inconsistent and flips between "charged" and "too weak to run." The battery is just totally unreliable and useless. I will be seeking a refund.

Arrived brand new in sealed package. Easy to install. Works like a charm. Life saver it is.

Works

UPDATED Review: At first, we were getting nice, long runs - well over her previous best of 75 minutes with the factory battery, which was long enough to complete a cleaning run on a single charge.However, in only 8 months, with two runs per week and one full charge and a partial charge per run, the battery now can't power our Roomba for even 60 minutes between charges and the charges are taking longer than before. A Lithium ion battery should not degrade that much after only about 60 charge cycles.I can't recommend this battery and downgraded my rating to 2 stars.

Running my roomba now no problems

Well worth the cost to upgrade the functionality of my Roomba. Charged up quickly and was easy to insert

Like-The battery has 4400mAh or ~4 times the amperage of the battery which originally came in the I robot 650 series vacuum. The I robot seems to work longer and clean better than with the original battery.
