Heavy truck battery and boost service

Common situations

• Starter clicks but the engine won’t turn over
• Batteries drained by an inverter, a heater or lights left on
• Hard starting in deep cold
• Corroded or loose terminals
• Truck parked for several days in a yard

What the technician does

The technician boosts the truck with equipment suited to heavy vehicles, checks terminals, cables and state of charge, and tells you whether a battery no longer holds a charge.

If a battery needs replacing, dispatch will tell you whether that can be done on site for your truck.

While you wait

Turn off accessories running on the batteries (inverter, auxiliary heater, cab lights) so they do not drain further, but keep the hazard lights on if the truck is stopped by a road.

What needs a shop

A failed starter or alternator is usually repaired in a shop. A boost may get you there; the technician will tell you what is safe.

To speed things up

• What happens when you turn the key: nothing, a click, slow cranking
• How long the truck has been parked
• The make and model of the tractor or truck
• Access to the battery box if it is locked
