Review on 🔋 TATTU 4500mAh XLife Extended Life Replacement Battery for iRobot Roomba R3 Series Models - Compatible with 500, 600, 700, 800, and 900 Series Models (530, 531, 532, 535, 536, 540, 550, 552, 560, 562, 570, 580, 595, 620, 630, 650, 660, 760, 770, 780, 790, 870, 880, and 980) by Guled Probz

Purchased and installed December 2018 Lasted until the end of April 2020 Now needs to dock in 20 minutes. I use my Roomba almost every day. So I give it a solid 3 stars or 3.5 for durability. The original battery lasted about 2.5 years. I only paid a third of the price for this battery. It worked well. If you count, it's a little better than buying an OEM. However, OEM will last two or three times longer. Buy based on your budget and the expected lifespan of your Roomba. My Rumba will soon be 6 years old. I have a rumba running that is over 10 years old. There were others who didn't work for 5 years. Everything required a battery change and some maintenance to get it working again. I love the Roomba product and when it dies I will upgrade to the latest model. However, I will not replace a perfectly working device, and in general, the rumba will last a long time. Again, some maintenance is required here from time to time. This is a good battery and it works. Expect around 1-1.5 years if you use Roomba every day. I do. All my Roomba vacuums start working at 7am every morning. i love rumba
