Going strong
Our old roomba can now complete a cycle without dying somewhere midway through vacuuming an hour into the job. The run cycle is now just as good if not better than it was when it was new. Definitely worth the price of replacing if it saves me from buying a new vacuum

The Melasta 5000mAh Lithium-Ion Battery is an excellent replacement for my iRobot Roomba. It’s compatible with multiple series (500, 600, 700, 800, 880), I have a 595 Pet from Costco making it a versatile and reliable option.With its 5000mAh capacity, this battery provides significantly longer runtime compared to the original. My Roomba now cleans more efficiently, covering more area in a single charge. Installation was straightforward, and it fit perfectly without any issues.If you’re looking to extend the life and performance of your Roomba, this replacement battery is a great choice. Highly recommended for its quality, compatibility, and extended runtime!

This battery lasted a year.
This is my 2nd time buying these batteries. My 1st on lasted a year, which doesn’t seem very long when you pay $50. I’m going to give them a second try and unplug my roomba dock when it’s done charging. I think it may be because it was kept charging all the time.

It works great!
I have a first generation Roomba that one day simply stopped working. I made the assumption that the battery must have finally died, and ordered this to replace it, making sure that it would fit the model of my specific Roomba. Immediately upon replacing it (very simple to install), my Roomba began working like new! It is still quite powerful after several months, is clearly durable, as yet shows no signs of aging. It still recharges quickly, too! Excellent value!

Works twice as good as original battery
We have an iroomba vacuum cleaner that is several years old and the battery was slowly decreasing the cleaning time and vacuum suction. My husband decided to replace the battery and found the new battery powered the vacuum for two hours. The original battery only powered the vacuum cleaner for 1 hour and it was down to less than 1/2 hour when we replaced it. There is also significantly more dust and dirt in the dust bin after 1 hour of running than there had been with the original battery.

Works great with our Roomba
Didn't know how I was going to like it at first. But it charges just like any other battery. The power lasts much longer than the old battery did. It's super easy to uninstall and reinstall. There are no jumps or any issues of functionality. And it was a good price.
