The cause of abnormal battery discharge, overcharging or early battery failure must be diagnosed and corrected before a battery is replaced and before a vehicle is returned to service.

It is important that the battery, starting, and charging systems be thoroughly tested and inspected any time a battery needs to be charged or replaced. In order for the engine to start and the battery to maintain its charge properly, all of the components that are used in these systems must perform within specifications. The battery, starting, and charging systems in the vehicle operate with one another and must be tested as a complete system. 2011 ELECTRICAL Battery System - Service Information - Compass & Patriotīattery System - Service Information - Compass & PatriotDiagnosis and TestingDIAGNOSIS AND TESTING - BATTERY SYSTEM
