Steps to Replace the Roomba 980 Battery

Troubleshooting Guide

-
Roomba Doesn’t Turn On After Battery Replacement:
- Solution: Ensure the battery is correctly seated and the black tabs are properly connected. Try removing and reinstalling the battery to ensure a firm connection.
-
New Battery Not Charging:
-
Solution: Clean the charging contacts on both the Roomba and the Home Base with a clean, lightly dampened melamine foam (like a Magic Eraser). Also, make sure the Home Base is stable and firmly placed.
-
Roomba Still Has Short Run Time After Battery Replacement:

Solution: Ensure the battery is sitting flush inside the compartment. Check for any obstructions or debris that might be preventing the cover from closing correctly.
