Checks and evidence, step by step

Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. 1

    Confirm where the battery came from

    No special tools

    Procedure

    Who:
    you.
    How:
    find the purchase record of the robot and of any replacement battery and check whether it is an authentic iRobot Lithium-Ion battery.
    Result that matters:
    whether the fitted battery is iRobot authentic.
    If it is aftermarket:
    that matches the code; ask iRobot or an authorized retailer about an authentic battery and have it fitted by service.
    If it is authentic:
    reboot the robot.
    Evidence to keep:
    the receipt or a photo of the battery packaging.

What it means

In iRobot's i Series chart, Error 23 is a battery authentication failure; iRobot's article says Error 23, like Charging Error 17, means the battery may not be iRobot authentic. The robot checks the battery pack's identity before using it, so an aftermarket battery is the usual trigger, and iRobot says this and other charging errors can occur with them. The code does not prove the battery is dangerous or that the robot is broken: if the battery is authentic and a reboot does not clear it, iRobot reviews the case.

Warnings and stop conditions
