Roomba i2 Charging Error 5 — Contacts / counterfeit battery

FM-11

Symptom: Most common charging fault: robot reports charging error 5; charging is intermittent or won't start; base light may flicker. Likely root causes: Dirty / oxidized charging contacts on the robot or the Home Base (most common); Counterfeit or incompatible battery; Robot not seated squarely on the base; Base not powered (its own light off) Next steps if owner-level checks fail: Error 5 continues with clean contacts, a powered base and a genuine battery — charge circuit may need service; contact iRobot Customer Care 1-877-855-8593
