All the batteries must be visually inspected before use

Inspection

• Visual Inspection
  • Terminals: Inspect both terminals (positive and negative) for signs of corrosion, discoloration, or loose grasshopper nuts. Ensure the terminals are not bent or damaged. Clean any corrosion using a clean cloth or a terminal cleaning tool if necessary.
  • Case Integrity: Inspect the battery casing for cracks, dents, bulges, or any deformation. Concentrate around the terminals, seams, and corners.
  • Labels and Markings: Ensure that all labels are intact and legible, including name and serial number
  • Leaking Fluids: Look for signs of leakage, such as dried residue or liquid near the terminals or seams.
• Cleanliness
  • Use a clean, dry cloth to remove dirt or residue from the battery's surface and terminals.
  • Do not use water or cleaning agents

Test and Check-in

1. Documentation
   • AT LEAST 30 MINUTES OFF THE CHARGER 
   • Give the battery a number (ex: 2501-B-9)
   • Take pre-voltage
   • Discharger: select custom, 18 amps, 9.7 V
   • After full discharge, collect post-voltage, capacity and charged internal resistance
   • Put the battery on the charger
   • Keep going until all of the batteries went through at least 2 rounds of testing

If you see any major issues, report them to mentor/put a warning sticker on
