New Roomba Battery is not Charging

To replace your old battery, you will need to unscrew the main screws underneath the Roomba and remove the plate that holds the battery down. Remove the old battery and insert the new one. Then reattach the plate the same way it was removed. See the first image below for an example.

To verify if your Roomba is docked and charging check the color of the LED light around the “CLEAN” button. It should flash orange when charging properly.

If it is not charging, the most common reason is dirt build-up on the contacts underneath your Roomba. Make sure these are cleaned regularly to prevent slow charging or failure to charge.

Another problem area is the contacts on your dock. These too can have dirt build-up. Also, the dirt can get underneath and clog the springs that help connect the dock to the contacts on the Roomba. If cleaning does not fix a poor connection, you can use something to lift the rear of the Roomba (opposite the dock) to help the Roomba push down against the contacts and improve connectivity.

Note: We use a Roomba in our office, and can test batteries sent back to us as “defective.” So far, 100% of the batteries returned to us because they would not work with the user’s Roomba have functioned properly in ours. Please utilize information above to ensure proper function with your new Roomba battery. If you are still having issues with your new Roomba battery please contact us.
