Both Charging Error Seventeen (17) and Error Twenty-Three (23) mean that the battery may not be iRobot authentic.
Note: Confirm that you are using an authentic iRobot® Lithium-Ion battery. This charging error and others can occur with aftermarket purchased batteries.
If the message persists, perform a robot reboot.
If the message persists after the reboot, and your battery is iRobot authentic, please contact iRobot Customer Care.
For expedited service, please have the following ready:
• Your robot charged and with you.
• Your robot's Serial Number.
• For warranty claims: Proof of purchase (receipt or invoice for purchase from an authorized retailer).
