Battery Charging
Charging
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 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. Use an external 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.
Charger Connected to Engine or Chassis Ground - Preferred Method
- 2.
Connect the negative (black) charger clamp to the negative battery ground cable bolt or the engine.
Charger Connected to Battery Posts
NOTE:
Vehicles equipped with 1.6L EcoBoost engine have a battery monitor sensor. The battery monitoring sensor relearns the battery's state of charge within 4-6 hours after the sensor is removed from the battery. For additional battery monitoring sensor information, refer to Charging System - General Information
.
