Inspection of the Batteries

Inspection of the Batteries - Gen 5 DD15 - Ops - #7628

Batteries should be inspected periodically. A good practice is to include the battery inspection as part of the pre-start inspection.

Inspect the batteries as follows:

  1. Inspect the overall condition of the batteries. Check for cracks in the battery cases.
  2. Inspect the cables, clamps and hold-down brackets regularly. If necessary, clean and reapply a light coating of petroleum jelly. Damaged or corroded parts should be replaced.
  3. Check battery connections for corrosion and tightness. If necessary, remove connections, wire brush any corrosion from terminals and cable ends and reapply a light coating of petroleum jelly.
    4. Note: If any of the above conditions exist it may be necessary to take the vehicle to an authorized Detroit™ service outlet.
  4. If the engine is to be out of service for more than 30 days, remove the batteries and store in a cool, dry place. Keep batteries fully charged. Have any batteries that fail to hold a charge replaced.
