iRobot® Lithium Ion Battery (ABL-D1)
The J7 utilizes a specific 14.4V Lithium-Ion battery. If the unit does not charge after cleaning contacts, the internal Battery Management System (BMS) has likely entered a permanent failure mode or the cells have dropped below a critical voltage threshold that the dock cannot recover. This is the most common granular component replaced to solve charging failures.

Clean Base® / Home Base Charging Station
The spring-loaded charging contacts on the base can lose tension or develop high-resistance carbon buildup. If the base fails to output the required 'wake-up' pulse to the robot, the charging cycle will never initiate, regardless of the robot's battery health.

Robot Bottom Cover with Charging Contacts
The metal charging plates on the underside of the J7 are subject to galvanic corrosion and physical erosion. If the plates are pitted or severely worn (as noted in the iFixit source), they cannot maintain a low-resistance connection, causing the charging logic to abort for safety.
