Quality replacement

This is the 2nd one I have bought, just to have a backup. Work the treat and can't beat the price.

These batteries are great for Roomba vacuum.They are long lasting.

battery fit and works perfectly

Fits like a glove and a true 1:1 drop in replacement.At almost 1/3 the price of the OEM it’s a great deal and hard to pass up.To replace is super easy, flip it over, loosen the 2 silver screws and open the cover, pull old battery out and insert new, close cover and tighten screws, you’re done. Simple as that.Functions very well and holds the charge; battery charging and Roomba app or the Roomba itself has had no issues with it.If your Roomba vacuums for less than 45 minutes and dies, time to replace the battery.Having 2 of them it makes it a no brainer to swap 2 batteries and still buy brushes and filters for the price of one retail battery.

For the price, this is the battery to beat. 6500mAh is the largest I think I've seen available for IRobot- and other batteries of this high capacity have given me charging errors in the past. This one though, worked perfectly. I was able to get a whopping 3 hours out of one of my roombas through running multiple cleaning runs in a row. Ideal for 980 series since they have carpet boost and drain batteries way faster than other batteries.

Its a much better deal to get this one with the 6500 ah instead of the 3300 you can definitely tell the difference it will run and run and run o this extran power battery its worth the extra money thats for sure I have to stop it because its a older model and it dosent have automatic dumping sonic have to dump it out and its always full thats a good thing showing even the older ones are still worth getting a new battery for there is still use for these old ones they work as good as new with new batteries and new brushes if you want to make it like new you can get all that stuff right here on amazon and it comes fast and easy instalation
