Review on Maximize Your IRobot'S Efficiency With SPARKOLE'S 5300MAh Extended Life Lithium Ion Battery For Roomba 500-800 Series by Louis Abrams

Super easy to install. If you follow the instructions about how to charge the battery your Roomba will run longer.Charge it fully and then run down fully 4 times and then set it on your schedule. The battery will last longer over the 4 times you train the battery. My run time lasted 3+ hours the second time I charged it after 2+ hours run time the first time. I will revisit this later but in my experience it works out better than the original battery ever did.
