Do Lead-acid Batteries Need Daily Cleaning? (2)

While daily cleaning is not necessary, if you notice any dirt or corrosion, clean the battery as follows:

  1. Gather Supplies:
    • Safety glasses and gloves
    • Baking soda
    • Water
    • A brush (non-metallic) or cloth
    • Petroleum jelly or battery terminal protector spray
  2. Safety First:
    • Wear safety glasses and gloves to protect yourself from electrolyte spills or splashes.
    • Ensure the battery is disconnected before cleaning.
  3. Clean the Terminals:
    • Mix a solution of baking soda and water (1 tablespoon of baking soda to 1 cup of water).
    • Use the brush or cloth to apply the baking soda solution to the terminals and any corroded areas. This neutralizes the acid.
    • Scrub gently to remove corrosion.
    • Rinse with clean water and dry with a clean cloth.
  4. Protect the Terminals:
    • After cleaning and drying, apply a thin layer of petroleum jelly or use a battery terminal protector spray to the terminals. This helps prevent future corrosion.
  5. Inspect and Reconnect:
    • Inspect the battery for any damage or leaks.
    • Reconnect the battery terminals securely.

Additional Tips

  • Keep the Battery Area Clean and Dry: Ensure the area around the battery is free of debris and moisture.
  • Monitor Charge Levels: Regularly check the charge level of the battery and recharge as necessary.
  • Ventilation: Ensure proper ventilation if the battery is installed in an enclosed space to prevent the buildup of hydrogen gas.

Special Considerations

  • Sealed Lead-Acid (SLA) Batteries: SLA batteries (such as AGM and Gel batteries) require less maintenance since they are sealed and do not require electrolyte checks or topping up. However, they still benefit from periodic inspection and cleaning of terminals.

By following these guidelines, you can maintain your lead-acid battery in good condition without the need for daily cleaning. Regular inspection and periodic maintenance will help ensure reliable performance and extend the battery’s lifespan.
