Good replacement for roomba
Delivered fast. Seems to be an exact replacement. Came partially charged so I used it for a while before charging. We'll see how long it holds up.

Fits, works, mine lasted only 18 months BUT THEY REPLACED IT FOR FREE
This kind of battery ought to be good for hundreds of charges.Unfortunately, my particular one had a bad cell and lost capacity after around 100 uses.After I gave them a one-star, they reached out to me and replaced the battery.EXCEPTIONALLY GOOD customer service

Charging
The batteries seem OK. After a handful of cycles, unable to charge, charging error 1 on the Roomba. Moved the temperature sensor from the original battery into new and works OK so far.

Buyer beware. It won’t last.
I never write reviews although I thought it was important for anyone who is considering buying this replacement battery. At first, this battery was great. Our Roomba would run full cycles and make it back to the base. After the first few weeks it was not running its full cycle and would not make it back to the dock. Each week it would run a minute or two less than the previous week…..fast forward to now and it is only able to run for a few minutes. It is useless now. Do not buy this battery. You have been warned.
