About Truck Battery Life
Lift gate motors consume a lot of battery power. Truck operators should keep the vehicle running whiile using the lift gate on the rear of the truck, as much as possible to prevent a dead battery. If the battery warning light appears on your dashboard or your truck fails to start after running the lift gate, contact your local branch for assistance.
Running the vehicle periodically during lift gate operation is an easy way to prevent issues which can result in expensive delays to your schedule. Driving and general idling will help to keep the batteries charged.
