Battery Charging Overview
WARNING:
Before beginning any service procedure in this service information, refer to SAFETY WARNINGS
NOTE:
Batteries discharge while the vehicle is on the dealer lot or parked by the customer for an extended period of time due to normal parasitic key-off loads. Also, vehicles still in dealer inventory or in long-term storage may be driven short distances with heavy electrical loads. Over a period of time (30 days or more), this could result in vehicles having shallow or deeply discharged batteries.
NOTE:
The vehicle charging system is designed to supply the electrical power needed to maintain the battery near full charge during normal vehicle use. The charging system is not capable of bringing a deeply discharged battery back to near full charge in a short amount of time such as allowing the vehicle to idle for 15 minutes to "recharge the battery." Discharged batteries should be charged using an external charger.
- 1.
Cold batteries will not readily accept a charge. Therefore, allow batteries to warm to approximately 5°C (41°F) before charging. This may require 4 to 8 hours at room temperature.
Charger Connected to Engine or Chassis Ground - Preferred Method
NOTE:
Use the combination battery charger and battery tester/analyzer GR 1 190 V3.0 Intelligent Diagnostic Charger or equivalent to charge the battery.
- 2.
Connect the negative (black) charger clamp to the negative battery ground cable stud bolt or the engine.
Charger Connected to Battery Posts
NOTE:
Use the combination battery charger and battery tester/analyzer GR 1 190 V3.0 Intelligent Diagnostic Charger or equivalent to charge the battery.
NOTE:
The Battery Monitoring Sensor (BMS) relearns the battery's state of charge within 4-6 hours after the sensor is removed from the battery. For additional BMS information, REFER to Charging System
