How do you replace an iRobot 900 Series Li-ion battery?
Answer
Confirm your robot is a 900 Series model, then buy a genuine iRobot Li-ion battery listed for the 900 Series—not a generic “compatible” pack—and install it after powering the robot down and removing the battery cover.
Before you start: stop right away if…
- Do not puncture, crush, or incinerate a Li-ion pack. Recycle the old battery at an approved battery drop-off if possible.
Follow these steps
Confirm the model and old part number
Check the model number on the bottom of the robot or in the iRobot app, then remove or view the battery label and write down the full part text (for example PA-1 style markings and numbers near the barcode).
You should see: You know which 900 Series model you have and what the outgoing battery is labeled.
Order a genuine 900 Series battery
Order from iRobot or a listing that specifically says authentic/OEM iRobot Li-ion battery for the 900 Series (or the series range your manual lists). Avoid listings that only say “compatible.”
You should see: The package you receive is clearly branded for iRobot and matches your series.
Power down and open the battery compartment
Turn the robot off, flip it over on a soft surface, and open the battery door using the method in your model’s manual.
You should see: You can see and lift out the old battery without forcing plastic tabs.
Install the new battery and charge
Insert the new battery in the same orientation as the old one, close the cover, place the robot on its Home Base or charger, and charge fully before the first cleaning job.
You should see: The robot powers on, accepts a charge, and no longer shows the end-of-life battery message after a full charge cycle.

Extra tips
What to look for: The part number and barcode text on the old battery, the robot model number on the bottom or in the app, and product listings that say genuine/OEM iRobot Li-ion for the 900 Series rather than only “compatible.”
Before you change anything: Write down the model number from the robot and the full text on the old battery label. Power the robot off and place it on a non-metal surface before opening the battery door. Buy from iRobot or a seller that clearly states OEM/authentic, not only “compatible.” Keep the old battery until the new one is installed and tested.
