What Are the Common Routine Maintenance of Lead-acid Batteries?

Common routine maintenance tasks for lead-acid batteries include:

  1. Checking and Topping Up Electrolyte Level: As mentioned earlier, the electrolyte level should be checked regularly, and if necessary, topped up with distilled water to maintain the proper acid concentration. This is particularly important in warmer climates where water can evaporate more quickly.
  2. Cleaning Battery Terminals and Connections: Over time, corrosion can build up on the battery terminals and connections, which can impede the flow of electricity and reduce the battery’s performance. The terminals and connections should be cleaned regularly using a mixture of baking soda and water, and a wire brush if necessary.
  3. Inspecting Battery Case and Cables: The battery case and cables should be inspected regularly for signs of damage or wear, such as cracks, leaks, or frayed cables. Any damage should be repaired or replaced as needed.
  4. Checking Battery Voltage and Specific Gravity: The battery voltage and specific gravity of the electrolyte can be checked using a multimeter and a hydrometer, respectively. This can help to identify any potential issues with the battery’s performance.
  5. Charging the Battery: Lead-acid batteries should be charged regularly to maintain their charge and prevent sulfation, which can occur when the battery is left in a discharged state for an extended period of time.
  6. Avoiding Overcharging: Overcharging can damage the battery and reduce its lifespan. It is important to use a charger that is appropriate for the battery’s size and type, and to avoid leaving the battery on charge for longer than necessary.

By performing these routine maintenance tasks, you can help to ensure that your lead-acid battery remains in good condition and provides reliable performance over its lifespan.
