Worked great and was well made

Works great!! Extended the life of my 6 year old Roomba.

Unit non-responsive in 1 month. Battery life was worse than old original iRobot vacuum from 2015 when first charged. I thought it needed a couple charge cycles but it never got better and died right after the return window closed.

The battery fit perfectly and now my robot vacuum is back to work.

This battery appears to be the same as the OEM battery and works just as well. I am very satisfied with the purchase.

Just replacement battery is awesome. More than three times the power of the original battery in the I Roomba makes our old Roomba run like new longer vacuuming time highly recommend five stars all the way. Will definitely re-buy as needed and very easy to install.

Fits perfect in my J7. It runs now like it did when I first got the Roomba. Ran for over an hour and still showed about a 50% charge and docked, which it hadn't been doing.

Easy to install accurate description
