Lead-acid batteries require regular maintenance to ensure optimal performance and longevity. Here are some key signs that your lead-acid battery may need maintenance:
External Signs of Wear
- Leaks, Cracks, or Swelling: Visible leaks, cracks, or swelling on the battery casing are indicators of potential internal damage or electrolyte leakage.
- Corrosion: Corrosion on the terminals can impede electrical flow, reducing battery efficiency.
- Bulging Sides: Bulging sides can indicate internal pressure issues.
- Rotten Egg Smell: A sour or rotten egg smell suggests electrolyte leakage or internal problems.
Performance Issues
- Decreased Capacity: If the battery discharges quickly or fails to hold a charge, it may indicate sulfation or internal degradation.
- Voltage Fluctuations: Significant deviations from the expected voltage (about 12.6 volts for a fully charged battery) can signal problems like sulfation.
Internal Signs
- Low Electrolyte Levels: If the water level is below the recommended marks, adding distilled water is necessary.
- Sulfation: Presence of lead sulfate crystals on plates, indicating undercharging or improper charging.
- Discoloration: Discoloration of posts or the case can indicate overheating, seal failure, or corrosion.
Maintenance Practices
- Regular Cleaning: Clean terminals with a baking soda solution and apply dielectric grease to prevent corrosion.
- Regular Charging and Storage: Ensure proper charging habits and store in a cool, dry environment to prevent degradation.
