Charging
WARNING:
Before beginning any service procedure in this article, refer to Safety Warnings in General Information. Failure to follow this instruction may result in serious personal injury.
NOTE:
Use only a lithium-ion battery maintainer to charge battery or component damage may occur.
NOTE:
Batteries will discharge due to normal parasitic key off-loads when the vehicle is on a dealer lot or parked by the customer for an extended period of time. Vehicles 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. Use a lithium-ion battery maintainer charger to charge discharged batteries.
NOTE:
Cold batteries will not readily accept a charge. Allow batteries to warm to approximately 5°C (41°F) before charging. This may require 4 to 8 hours at room temperature.
- Connect a lithium-ion battery maintainer positive (red) charger clamp to the underhood BJB service terminal.
- Connect the lithium-ion battery maintainer negative (black) charger clamp to the negative battery ground cable stud.
- Charge the battery following the battery charger manufacturer's instructions.
