May 21, 2012

Before Charging
  • Always wear your protective equipment
    • Indicatively goggles, face shield, rubber apron and boots
  • Charge the batteries only when they are in need of charging 
    • A point of 20% capacity is recommended
  • The battery should be at approximately room temperature 
    • Never charge a “frozen” or a “hot” battery
  • Before start charging the battery, inspect both the charger, the battery and their handling systems for cracks, worn cables, damaged connectors etc.
    • If you notice any problem fix it immediately – in any case do not proceed with charging
  • The battery charger must match the battery
    • The charger must output the same voltage as the battery
  • Avoid “opportunity charging”, meaning partial charging during breaktimes
During Charging
  • Prohibit anything that can ignite the gas, being generated during battery charging
    • E.g. sparks, open flames, smoking, etc.
  • Always allow the battery to complete its charging cycle
    • Check the charger
  • Keep the charging area clean and well equipped
    • Have well-ventilated designated charging areas, with proper battery handling equipment (e.g. overhead hoists, lifting beams, battery racks and cranes)
After Charging
  • Water your forklift batteries immediately after charging, only with distilled or de-ionized water
    • Top up each cell separately, but do not overfill
  • Batteries must be kept in a cool and dry place
  • Keep your batteries clean
    • A clean battery is a healthy battery
  • Update your charging and watering log file
