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

This battery has my Roomba running like brand new. I used to marvel when it ran for hours and did a Grest job vacuuming. I purchased a replacement on here a while ago. It constantly died away from the dock and did not run very long. This Battery is the real deal! Highly recommend! Also got a refresh brush and filter kit. My 9 year old Roomba is running like New!
