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

After leaving my roomba unplugged during construction on my house I found his battery (which is many years old, honestly) was not charging any longer. I found this and took the chance and I’m glad I did. My roomba is back to fighting carpets and unplugging my fish tank like the old days.
