This product is very easy to install, but here's a trick I learned after installing it. Roomba worked fine after I put a new battery in it. But after the first start it started giving an error code, looked at it and gave a bad battery code. I googled it and it says you can get this with a new battery as long as it's not secured in the case. So I removed the cover and looked, the yellow tabs on the side of the battery had been torn off. This is what they looked like when I received them in the mail. So I folded them over the battery and sealed them with tape. This put a seal on top so the plastic cover pushed the battery down so the contacts would make contact if you turned the Roomba over. After that I followed the prompts and rebooted the battery by holding down the Spot and Dock buttons for 10 seconds until the lights went out and then pressing the Clean button once. If that doesn't work, you can continue to add padding above the tabs until the problem is resolved.
