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

  • No labels
