• Inter-cell connectors.
  
• Cables.
  
• Hardware cell elements.
  
• Cell covers.
  
• Containers.
  
• Post seals.
  
• Gravity tubes.
  
• Safety vents.
  
• Flash arrestors.
  
• Battery racks.

Measure, check, record, and adjust if necessary:

• Total battery float voltage.
  
• Total battery ripple voltage.
  
• Positive to ground voltage.
  
• Negative to ground voltage.
  
• Total battery ripple current.
  
• Float voltage on each cell.
  
• Specific gravity and electrolyte temperature each cell.
  
• Each cell to cell terminal, and cable connections using a micro-ohm meter to verify that the connection resistances are within 20% of the average contact resistance.

Clean and neutralize all cell surfaces, and add distilled water to cells to maintain the required electrolyte levels if needed.

Check and record room ambient temperature, verify proper operation of ventilation equipment, and room cleanliness.

Documentation of inspection with recommendations for any corrective action deemed necessary will be provided.
