Review on 🔋 4.5Ah 14.4V Ni-Mh Replacement Battery for iRobot Roomba R3 500/600/700/800/900 Series by Jessica Martin

I ordered this battery because my previous one didn't last as long without charging. When I charged this battery it only lasted about 1/2 hour while the previous one lasted at least an hour when I stopped using it! I recycled my old battery and got rid of the packaging from it, otherwise I would have sent it back. I have ordered replacement batteries from Revain twice and have been satisfied, but this one is not at all satisfactory. Very disappointed.
